Congress of Industrial Organizations

The Congress of Industrial Organizations (CIO) was a federation of unions that organized workers in industrial unions in the United States and Canada from 1935 to 1955. Created in 1935 by John L. Lewis, who was a part of the United Mine Workers (UMW), it was originally called the Committee for Industrial Organization but changed its name in 1938 when it broke away from the American Federation of Labor.[1] It also changed names because it was not successful with organizing unskilled workers with the AFL.[2]

The CIO supported Franklin D. Roosevelt and the New Deal Coalition, and was open to African Americans. Both the CIO and its rival the AFL grew rapidly during the Great Depression. The rivalry for dominance was bitter and sometimes violent. The CIO (Congress for Industrial Organization) was founded on November 9, 1936, by eight international unions belonging to the American Federation of Labor.

In its statement of purpose, the CIO said it had formed to encourage the AFL to organize workers in mass production industries along industrial union lines. The CIO failed to change AFL policy from within. On September 10, 1936, the AFL suspended all 10 CIO unions (two more had joined in the previous year). In 1938, these unions formed the Congress of Industrial Organizations as a rival labor federation. The Taft-Hartley Act of 1947 required union leaders to swear that they were not Communists. Many CIO leaders refused to obey that requirement, later found unconstitutional. In 1955, the CIO rejoined the AFL, forming the new entity known as the American Federation of Labor-Congress of Industrial Organizations (AFL-CIO).

The CIO was born out of a fundamental dispute within the United States labor movement over whether and how to organize industrial workers. The eight union chiefs who founded the CIO were not happy with how the AFL was unwilling to work with America's manufacturing combines.[4] Those who favored craft unionism believed that the most effective way to represent workers was to defend the advantages that they had secured through their skills. They focused on the hiring of skilled workers, such as carpenters, lithographers, and railroad engineers in an attempt to maintain as much control as possible over the work their members did by enforcement of work rules, zealous defense of their jurisdiction to certain types of work, control over apprenticeship programs, and exclusion of less-skilled workers from membership.

Craft unionists were opposed to organizing workers on an industrial basis, into unions that represented all of the production workers in a particular enterprise, rather than in separate units divided along craft lines.

The proponents of industrial unionism, on the other hand, generally believed that craft distinctions may have been appropriate in those industries in which craft unions had flourished, such as construction or printing, but they were unworkable in industries such as steel or auto production. In their view, dividing workers in a single plant into a number of different crafts represented by separate organizations, each with its own agenda, would weaken the workers' bargaining power and leave the majority, who had few traditional craft skills, completely unrepresented.

While the AFL had always included a number of industrial unions, such as the United Mine Workers and the Brewery Workers, the most dogmatic craft unionists had a strong hold on power within the federation by the 1930s. They used that power to quash any drive toward industrial organizing.[1]

Industrial unionism became even more fierce in the 1930s, when the Great Depression in the United States caused large membership drops in some unions, such as the United Mine Workers and the International Ladies' Garment Workers' Union. A number of labor leaders, particularly John L. Lewis of the United Mine Workers, came to the conclusion that their own unions would not survive while the great majority of workers in basic industry remained nonunion. They started to press the AFL to change its policies in this area.

The AFL, in fact, responded and added even more new members than the CIO. The AFL had long permitted the formation of "federal" unions, which were affiliated directly with the AFL; in 1933, it proposed to use them to organize workers on an industrial basis. The AFL did not, however, promise to allow the unions to maintain a separate identity indefinitely. That meant the unions might be broken up later to distribute their members among the craft unions that claimed jurisdiction over their work. The AFL, in fact, dissolved hundreds of federal unions in late 1934 and early 1935.

While the bureaucratic leadership of the AFL was unable to win strikes, three victorious strikes suddenly exploded onto the scene in 1934. These were the Minneapolis Teamsters Strike of 1934, the leadership of which included some members of the Trotskyist Communist League of America; the 1934 West Coast Longshore Strike, the leadership of which included some members of the Communist Party USA; and the 1934 Toledo Auto-Lite strike, which was led by the American Workers Party. Victorious industrial unions with militant leaderships were the catalyst that brought about the rise of the CIO.

The AFL authorized organizing drives in the automobile, rubber, and steel industries at its convention in 1934 but gave little financial support or effective leadership to those unions. The AFL's timidity succeeded only in making it less credible among the workers that it was supposedly trying to organize. That was especially significant in those industries, such as auto and rubber, in which workers had already achieved some organizing success, at great personal risk.

The dispute came to a head at the AFL's convention in Atlantic City in 1935, when William Hutcheson, the President of the United Carpenters, made a slighting comment about a rubber worker who was delivering an organizing report. Lewis responded that Hutcheson's comment was "small potatoes," and Hutcheson replied, "I was raised on small potatoes, that is why I am so small." After some more words, Lewis punched Hutcheson, knocking him to the ground. Lewis then relit his cigar and returned to the rostrum. The incident, which was also "small potatoes" but very memorable, helped cement Lewis's image in the public eye as someone willing to fight for workers' right to organize.


Shortly afterward, Lewis called together Charles Howard, President of the International Typographical Union; Sidney Hillman, head of the Amalgamated Clothing Workers of America; David Dubinsky, President of the ILGWU, Thomas McMahon, head of the United Textile Workers; John Sheridan of the Mine, Mill and Smelter Workers Union; Harvey Fremming, of the Oil Workers Union; and Max Zaritsky, of the Hatters, Cap and Millinery Workers. They discussed the formation of a new group within the AFL to carry on the fight for industrial organizing. The creation of the CIO was announced on November 9, 1935.[5]

Whether Lewis then intended to split the AFL over this issue is debatable; at the outset, the CIO presented itself as only a group of unions within the AFL gathered to support industrial unionism, rather than a group opposed to the AFL itself.

The AFL leadership, however, treated the CIO as an enemy from the outset by refusing to deal with it and demanding that it dissolve. The AFL's opposition to the CIO, however, only increased the stature of the CIO and Lewis in the eyes of the industrial workers who were keen on organizing and were disillusioned with the AFL's ineffective performance. Lewis continued to denounce the AFL's policies, and the CIO offered organizing support to workers in the rubber industry who went on strike and formed the Steel Workers Organizing Committee (SWOC) in defiance of all of the craft divisions that the AFL had required in past organizing efforts. In 1936, Lee Pressman, affiliated with the far left, became the union's general counsel until 1948.

The first major industrial union to be chartered by the CIO, on November 16, 1938, was the United Electrical, Radio and Machine Workers of America (UE).

The subsequent explosive growth of the UE was instrumental for the survival in the early days of the CIO. By the end of 1936, the UE had organized the General Electric plant at Schenectady, New York, and the UE went on to organize 358 more local unions with contracts covering over 600,000 workers, at 1375 plants.

Initial triumphs

The CIO met with dramatic initial successes in 1937, with the UAW winning union recognition at General Motors Corporation after a tumultuous forty-four-day sit-down strike, while the Steel Workers Organizing Committee (SWOC) signed a collective bargaining agreement with U.S. Steel. Those two victories, however, came about very differently.

The CIO's initial strategy was to focus its efforts in the steel industry and then build from there. The UAW, however, did not wait for the CIO to lead it. Instead, having built up a membership of roughly 25,000 workers by gathering in federal unions and some locals from rival unions in the industry, the union decided to go after GM, the largest car maker of them all, by shutting down its nerve center, the production complex in Flint, Michigan.

The Flint Sit-Down Strike was a risky and illegal enterprise from the outset: the union was able to share its plans with only a few workers because of the danger that spies employed by GM would alert management in time to stop it, yet needed to be able to mobilize enough to seize physical control of GM's factories. The union, in fact, not only took over several GM factories in Flint, including one that made the dies necessary to stamp automotive body parts and a companion facility in Cleveland, Ohio, but held on to those sites despite repeated attempts by the police and National Guard to retake them and court orders threatening the union with ruinous fines if it did not call off the strike.

While Lewis played a key role in negotiating the one-page agreement that ended the strike with GM's promise to recognize the UAW as the exclusive bargaining representative of its employees for a six months period, UAW activists, rather than CIO staff, led the strike.

The organizing campaign in the steel industry, by contrast, was a top-down affair. Lewis, who had a particular interest in organizing the steel industry because of its important role in the coal industry where UMW members worked, dispatched hundreds of organizers, many his past political opponents or radicals drawn from the Communist-led unions that had attempted to organize the industry earlier in the 1930s, to sign up members. Lewis was not particularly concerned with the political beliefs of his organizers, so long as he controlled the organization; as he once famously remarked, when asked about the "reds" on the SWOC staff, "Who gets the bird? The hunter or the dog?".

The SWOC signed up thousands of members and absorbed a number of company unions at U.S. Steel and elsewhere, but did not attempt the sort of daring strike that the UAW had pulled off against GM. Instead Lewis was able to extract a collective bargaining agreement from U.S. Steel, which had previously been an implacable enemy of unions, by pointing to the chaos and loss of business that GM had suffered by fighting the UAW. The agreement provided for union recognition, a modest wage increase and a grievance procedure. CIO unions signed multiyear contracts, often complicated and long, with GM, U.S. Steel, and other corporations in order to minimize strikes and also make sure employers took care of the work process.[6]

The CIO also won several significant legal battles. Hague v. Committee for Industrial Organization 307 U.S. 496 (1939), arose out of events late in 1937. Jersey City, New Jersey Mayor Frank "Boss" Hague had used a city ordinance to prevent labor meetings in public places and stop the distribution of literature pertaining to the CIO's cause. District and circuit courts ruled in favor of the CIO. Hague appealed to the United States Supreme Court, which held in 1939 that Hague's ban on political meetings violated the First Amendment right to freedom of assembly.

Early setbacks and successes

The UAW was able to capitalize on its stunning victory over GM by winning recognition at Chrysler and smaller manufacturers. It then focused its organizing efforts on Ford, sometimes battling company security forces as at the Battle of the Overpass on May 26, 1937. At the same time, the UAW was in danger of being torn apart by internal political rivalries. Homer Martin, the first president of the UAW, expelled a number of the union organizers who had led the Flint sit-down strike and other early drives on charges that they were communists. In some cases, such as Wyndham Mortimer, Bob Travis and Henry Kraus, those charges may have been true; in other cases, such as Victor Reuther and Roy Reuther, they were probably not. Those expulsions were reversed at the next convention of the UAW in 1939, which expelled Martin instead. He took approximately 20,000 UAW members with him to form a rival union, known for a time as the UAW-AFL. The SWOC encountered equally serious problems: after winning union recognition after a strike against Jones & Laughlin Steel, SWOC's strikes against the rest of "Little Steel," i.e., Bethlehem Steel Corporation, Youngstown Sheet and Tube, National Steel, Inland Steel American Rolling Mills and Republic Steel failed, in spite of support from organizations like the Catholic Radical Alliance. The steelmakers offered workers the same wage increases that U.S. Steel had offered. In the Memorial Day Massacre on May 30, 1937, Chicago police opened fire on a group of strikers who had attempted to picket at Republic Steel, killing ten and seriously wounding dozens. A month and a half later police in Massillon, Ohio fired on a crowd of unionists, resulting in three deaths, when one union supporter failed to dim his headlights.

After some time passed between the disputes of the AFL and the CIO; the CIO began to grow larger as a union as it printed its own newspaper. The newspaper featured articles that were written by big journalists, cartoons, and other political stories. The newspaper had spread to 40% of the CIO's members and had different stories for different areas.[1]

The CIO found organizing textile workers in the South even harder. As in steel, these workers had abundant recent first-hand experience of failed organizing drives and defeated strikes, which resulted in unionists being blacklisted or worse. In addition, the intense antagonism of white workers toward black workers and the conservative political and religious milieu made organizing even harder. On the other hand, some independent left-wing unions, such as Mine, Mill and the Food, Tobacco, Agricultural, and Allied Workers Union of America.

Adding to the uncertainties for the CIO was its own internal disarray. When the CIO formally established itself as a rival to the AFL in 1938, renaming itself as the Congress of Industrial Organizations, the ILGWU and the Millinery Workers left the CIO to return to the AFL. Lewis feuded with Hillman and Philip Murray, his long-time assistant and head of the SWOC, over both the CIO's own activities and its relations with the FDR administration. Lewis finally resigned as President of the CIO in 1941, after endorsing Wendell Willkie for President in 1940. The doldrums did not last forever, however. The UAW finally organized Ford in 1941. The SWOC, now known as the United Steel Workers of America, won recognition in Little Steel in 1941 through a combination of strikes and National Labor Relations Board elections in the same year. In addition, after the west coast longshoremen organized in the strike led by Harry Bridges in 1934 split from the International Longshoremen's Association in 1937 to form the International Longshoremen's and Warehousemen's Union, the ILWU joined the CIO. Bridges became the most powerful force within the CIO in California and the west. The Transport Workers Union of America, originally representing the subway workers in New York, also joined, as did the National Maritime Union, made up of sailors based on the east coast, and the United Electrical, Radio and Machine Workers.

The AFL continued to fight the CIO, forcing the NLRB to allow skilled trades employees in large industrial facilities the option to choose, in what came to be called "Globe elections," between representation by the CIO or separate representation by AFL craft unions. The CIO now also faced competition, moreover, from a number of AFL affiliates who now sought to organize industrial workers. The competition was particularly sharp in the aircraft industry, where the UAW went head-to-head against the International Association of Machinists, originally a craft union of railroad workers and skilled trade employees. The AFL organizing drives proved even more successful, and they gained new members as fast or faster than the CIO.

Growth during the Second World War

The unemployment problem ended in the United States with the beginning of World War II, as stepped up wartime production created millions of new jobs, and the draft pulled young men out. The war mobilization also changed the CIO's relationship with both employers and the national government.

Having failed to ally with capitalist countries against fascism in the eves of the World War II, in August 1939 the Soviet Union signed a non-aggression pact with Nazi Germany, the Molotov–Ribbentrop Pact, which would later be broken by the Nazis. Many Communists in Western parties repudiated this action and resigned their party membership in protest. American Communists took the public position of being opposed to the war against Germany. The Mine Workers led by Lewis, with a strong pro-Soviet presence, opposed Roosevelt's reelection in 1940 and left the CIO in 1942. After June 1941, when Germany invaded the Soviet Union, the Communists became fervent supporters of the war and sought to end wildcat strikes that might hurt war production. The CIO, and in particular the UAW, supported a wartime no-strike pledge that aimed to eliminate not only major strikes for new contracts, but also the innumerable small strikes called by shop stewards and local union leadership to protest particular grievances.

That pledge did not, however, actually eliminate all wartime strikes; in fact there were nearly as many strikes in 1944 as there had been in 1937. But those strikes tended to be far shorter and far less tumultuous than the earlier ones, usually involving small groups of workers over working conditions and other local concerns.

The CIO did not, on the other hand, strike over wages during the war. In return for labor's no-strike pledge, the government offered arbitration to determine the wages and other terms of new contracts. Those procedures produced modest wage increases during the first few years of the war, but, over time, not enough to keep up with inflation, particularly when combined with the slowness of the arbitration machinery.

Yet even though the complaints from union members about the no-strike pledge became louder and more bitter, the CIO did not abandon it.[8] The Mine Workers, by contrast, who did not belong to either the AFL or the CIO for much of the war, engaged in a successful twelve-day strike in 1943.

But the CIO unions on the whole grew stronger during the war. The government put pressure on employers to recognize unions to avoid the sort of turbulent struggles over union recognition of the 1930s, while unions were generally able to obtain maintenance of membership clauses, a form of union security, through arbitration and negotiation. Workers also won benefits, such as vacation pay, that had been available only to a few in the past while wage gaps between higher skilled and less skilled workers narrowed.

The experience of bargaining on a national basis, while restraining local unions from striking, also tended to accelerate the trend toward bureaucracy within the larger CIO unions. Some, such as the Steelworkers, had always been centralized organizations in which authority for major decisions resided at the top. The UAW, by contrast, had always been a more grassroots organization, but it also started to try to rein in its maverick local leadership during these years.

The CIO also had to confront deep racial divides in its own membership, particularly in the UAW plants in Detroit where white workers sometimes struck to protest the promotion of black workers to production jobs. It also worked on this issue in shipyards in Alabama, mass transit in Philadelphia, and steel plants in Baltimore. The CIO leadership, particularly those in more left unions such as the Packinghouse Workers, the UAW, the NMU and the Transport Workers, undertook serious efforts to suppress hate strikes, to educate their membership and to support the Roosevelt Administration's tentative efforts to remedy racial discrimination in war industries through the Fair Employment Practices Commission. Those unions contrasted their relatively bold attack on the problem with the timidity and racism of the AFL.

The CIO unions were less progressive in dealing with sex discrimination in wartime industry, which now employed many more women workers in nontraditional jobs. Some unions who had represented large numbers of women workers before the war, such as the UE and the Food and Tobacco Workers, had fairly good records of fighting discrimination against women; others often saw them as merely wartime replacements for the men in the armed forces.

The post-War era

The end of the war meant the end of the no-strike pledge and a wave of strikes as workers sought to make up the ground they had lost, particularly in wages, during the war. The UAW went on strike against GM in November 1945; the Steelworkers, UE and Packinghouse Workers struck in January 1946.

Murray, as head of both the CIO and the Steelworkers, wanted to avoid a wave of mass strikes in favor of high-level negotiations with employers, with government intervention to balance wage demands with price controls. That project failed when employers showed that they were not willing to accept the wartime status quo, but instead demanded broad management rights clauses to reassert their workplace authority, while the new Truman administration proved unwilling to intervene on labor's side.

The UAW took a different tack: rather than involve the federal government, it wanted to bargain directly with GM over management issues, such as the prices it charged for its cars, and went on strike for 113 days over these and other issues. The union eventually settled for the same wage increase that the Steelworkers and the UE had gotten in their negotiations; GM not only did not concede any of its managerial authority, but never even bargained over the UAW's proposals over its pricing policies.

These strikes were qualitatively different from those waged over union recognition in the 1930s: employers did not try to hire strikebreakers to replace their employees, while the unions kept a tight lid on picketers to maintain order and decorum even as they completely shut down some of the largest enterprises in the United States.

The CIO's major organizing drive of this era, Operation Dixie, aimed at the textile workers of the American South, was a complete failure. The CIO was reluctant to confront Jim Crow segregation laws. Although the Steelworkers' Southern outpost in the steel industry remained intact, the CIO and the union movement as a whole remained marginalized in the Deep South and surrounding states.

In July 1943, the CIO formed the first-ever political action committee in the United States, the CIO-PAC, to help elected Roosevelt.

In 1946, the Republican Party took control of both the House and Senate. That Congress passed the Taft-Hartley Act, which made organizing more difficult, gave the states authority to pass right to work laws, and outlawed certain types of strikes and secondary boycotts. It also required all union officers to sign an affidavit that they were not Communists in order for the union to bring a case before the NLRB. This affidavit requirement, later declared unconstitutional by the United States Supreme Court, was the first sign of serious trouble ahead for a number of Communists in the CIO.

Purging the communists

Robert R. McCormick, publisher of the Chicago Tribune, who with some reluctance supported Thomas E. Dewey, the governor of New York and the 1944 Republican presidential nominee, claimed that the CIO had become the dominant faction in the national Democratic Party:

They call it the Democratic national convention but obviously it is the CIO convention. Franklin D. Roosevelt is the candidate of the CIO and the Communists because they know if elected, he will continue to put the government of the United States at their service, at home and abroad. ... The CIO is in the saddle and the Democrat donkey, under whip and spur, is meekly taking the road to communism and atheism. ... Everybody knows that Roosevelt is the Communist candidate, but even the Communists cannot be sure where their place will be if he wins. His purpose is to overthrow the Republic for his own selfish ambitions [but] it is the duty of every American to oppose The Great Deceiver [Roosevelt].[9]

The Taft Hartley Act of 1947 penalized unions whose officers failed to sign statements that they were not members of the Communist Party. Many Communists held power in the CIO unions (few did so in the AFL). The most affected unions were the ILWU, UE, TWU, United Public Workers, and Fur and Leather Workers. Other Communists held senior staff positions in a number of other unions.

The leftists had an uneasy relationship with Murray while he headed the CIO. He mistrusted the radicalism of some of their positions and was innately far more sympathetic to anti-Communist organizations such as the Association of Catholic Trade Unionists. He also believed, however, that making anti-Communism a crusade would only strengthen labor's enemies and the rival AFL at a time when labor unity was most important.

Murray might have let the status quo continue, even while Walter Reuther and others within the CIO attacked Communists in their unions, if the CPUSA had not chosen to back Henry A. Wallace's Progressive Party campaign for President in 1948. That, and an increasingly bitter division over whether the CIO should support the Marshall Plan, brought Murray to the conclusion that peaceful co-existence with Communists within the CIO was impossible.

Murray began by removing Bridges from his position as the California Regional Director for the CIO and firing Lee Pressman as General Counsel of both the Steelworkers and the CIO. Anti-communist unionists then took the battle to the City and State Councils where they ousted Communist leaders who did not support the CIO's position favoring the Marshall Plan and opposing Wallace.

After the 1948 election, the CIO took the fight one step further, expelling the International Longshore and Warehouse Union; International Union of Mine, Mill, and Smelter Workers; Farm Equipment Union (FE); Food and Tobacco Workers; and the International Fur and Leather Workers Union after a series of internal trials in the first few months of 1950, while creating a new union, the International Union of Electrical, Radio and Machine Workers (which later merged with the Communications Workers of America), to replace the United Electrical, Radio and Machine Workers (UE), which left the CIO.

Merger with the AFL

Reuther succeeded Murray, who died in 1952, as head of the CIO. William Green, who had headed the AFL since the 1920s, died the same month. Reuther began discussing merger of the two organizations with George Meany, Green's successor as head of the AFL, the next year.[10]

Most of the critical differences that once separated the two organizations had faded since the 1930s. The AFL had not only embraced industrial organizing, but included industrial unions, such as the International Association of Machinists, that had become as large as the UAW or the Steelworkers.

The AFL had a number of advantages in those negotiations. It was, for one thing, twice as large as the CIO. The CIO was, for its part, once again facing internal rivalries that threatened to seriously weaken it.

Reuther was spurred toward merger by the threats from David J. McDonald, Murray's successor as President of the Steelworkers, who disliked Reuther intensely, insulted him publicly and flirted with disaffiliation from the CIO. While Reuther set out a number of conditions for merger with the AFL, such as constitutional provisions supporting industrial unionism, guarantees against racial discrimination, and internal procedures to clean up corrupt unions, his weak bargaining position forced him to compromise most of these demands. Although the unions that made up the CIO survived, and in some cases thrived, as members of the newly created AFL-CIO, the CIO as an organization was folded into the AFL-CIO's Industrial Union Department.

Now, the AFL-CIO is made up of 56 national and international labor unions with 12.5 million members.[11]

The American Federation of Labor and Congress of Industrial Organizations (AFL-CIO) is the largest federation of unions in the United States. It is made up of fifty-five national and international unions, together representing more than 12 million active and retired workers. The AFL-CIO engages in substantial political spending and activism, typically in support of Democrats and liberal or progressive policies.The AFL-CIO was formed in 1955 when the AFL and the CIO merged after a long estrangement. Membership in the union peaked in 1979, when the AFL-CIO had nearly twenty million members. From 1955 until 2005, the AFL-CIO's member unions represented nearly all unionized workers in the United States. Several large unions split away from AFL-CIO and formed the rival Change to Win Federation in 2005, although a number of those unions have since re-affiliated. The largest unions currently in the AFL-CIO are the American Federation of Teachers (AFT) with approximately 1.7 million members and American Federation of State, County and Municipal Employees (AFSCME), with approximately 1.4 million members.

Amalgamated Clothing Workers of America

The Amalgamated Clothing Workers of America (ACWA) was a United States labor union known for its support for "social unionism" and progressive political causes. Led by Sidney Hillman for its first thirty years, it helped found the Congress of Industrial Organizations. It merged with the Textile Workers Union of America (TWUA) in 1976 to form the Amalgamated Clothing and Textile Workers Union (ACTWU), which merged with the International Ladies' Garment Workers' Union in 1995 to create the Union of Needletrades, Industrial and Textile Employees (UNITE). UNITE merged in 2004 with the Hotel Employees and Restaurant Employees Union (HERE) in 2004 to create a new union known as UNITE HERE. After a bitter internal dispute in 2009, the majority of the UNITE side of the union, along with some of the disgruntled HERE locals left UNITE HERE, and formed a new union named Workers United, led by former UNITE president Bruce Raynor.

Arthur Goldberg

Arthur Joseph Goldberg (August 8, 1908 – January 19, 1990) was an American statesman and jurist who served as the 9th U.S. Secretary of Labor, an Associate Justice of the Supreme Court of the United States, and the 6th United States Ambassador to the United Nations.

Born in Chicago, Illinois, Goldberg graduated from the Northwestern University School of Law in 1930. He became a prominent labor attorney and helped arrange the merger of the American Federation of Labor and the Congress of Industrial Organizations. During World War II, he served in the Office of Strategic Services, organizing European resistance to Nazi Germany. In 1961, President John F. Kennedy appointed Goldberg as the Secretary of Labor.

In 1962, Kennedy successfully nominated Goldberg to the Supreme Court to fill a vacancy caused by the retirement of Felix Frankfurter. Goldberg aligned with the liberal bloc of justices and wrote the majority opinion in Escobedo v. Illinois. In 1965, Goldberg resigned from the bench to accept appointment by President Lyndon B. Johnson as the Ambassador to the United Nations. In that role, he helped draft UN Resolution 242 in the aftermath of the Six-Day War. He ran for the position of Governor of New York in 1970 but was defeated by Nelson Rockefeller. After his defeat, he served as president of the American Jewish Committee and continued to practice law.


The first-ever "political action committee" in the United States of America was the Congress of Industrial Organizations - Political Action Committee or CIO-PAC. What distinguished the CIO-PAC from previous political groups (including the AFL's political operations) was its "open, public operation, soliciting support from non-CIO unionists and from the progressive public... Moreover, CIO political operatives would actively participate in intraparty platform, policy, and candidate selection processes, pressing the broad agenda of the industrial union movement."

Canadian Congress of Labour

The Canadian Congress of Labour (CCL) was founded in 1940 and merged with Trades and Labour Congress of Canada (TLC) to form the Canadian Labour Congress (CLC) in 1956.

Communications Workers of America

Communications Workers of America (CWA) is the largest communications and media labor union in the United States, representing about 700,000 members in both the private and public sectors(also in Canada and Puerto Rico). The union has 27 locals in Canada via CWA-SCA Canada (Syndicat des communications d'Amérique) representing about 8,000 members. CWA has several affiliated subsidiary labor unions bringing total membership to over 700,000. CWA is headquartered in Washington, DC, and affiliated with the AFL-CIO, the Canadian Labour Congress, and UNI Global Union. The current president is Chris Shelton.

Craft unionism

Craft unionism refers to a model of trade unionism in which workers are organised based on the particular craft or trade in which they work. It contrasts with industrial unionism, in which all workers in the same industry are organized into the same union, regardless of differences in skill.

Craft unionism is perhaps best exemplified by many of the construction unions that formed the backbone of the old American Federation of Labor (which later merged with the industrial unions of the Congress of Industrial Organizations to form the AFL–CIO). Under this approach, each union is organized according to the craft, or specific work function, of its members. For example, in the building trades, all carpenters belong to the carpenters' union, the plasterers join the plasterers' union, and the painters belong to the painters' union. Each craft union has its own administration, its own policies, its own collective bargaining agreements and its own union halls. The primary goal of craft unionism is the betterment of the members of the particular group and the reservation of job opportunities to members of the union and those workers allowed to seek work through the union's hiring hall.

This distinction between craft and industrial unionism was a hotly contested issue in the first four decades of the twentieth century, as the craft unions that held sway in the American Federation of Labor sought to block other unions from organizing on an industrial basis in the steel and other mass production industries. The dispute ultimately led to the formation of the Congress of Industrial Organizations, which split from the AFL to establish itself as a rival organization. The distinction between craft and industrial unions persists today, but no longer has the political significance it once had.

Hague v. Committee for Industrial Organization

Hague v. Committee for Industrial Organization, 307 U.S. 496 (1939), is a US labor law case decided by the United States Supreme Court.

International Labor Communications Association

The International Labor Communications Association (ILCA) is a professional organization for trade union publications and media production departments of national, regional and/or local affiliates of the AFL-CIO and Canadian Labour Congress. It is a nonpartisan, non-profit organization which provides resources, expertise and networking opportunities for labor communicators.

The ILCA was founded in 1955 as the International Labor Press Association. Its formation was brought about by the merger of the American Federation of Labor and the Congress of Industrial Organizations. The body was established as a means of coordinating the message of the new organization in labor newsletters, newspapers and magazines throughout the labor movements. It changed its name to ILCA in 1985.

The ILCA is not a competitor to the Canadian Association of Labour Media/Association canadienne de la presse syndicale (CALM/acps) (the organization representing labor media in Canada). The ILCA and CALM/acps share the goal of increasing the effectiveness of labor media and promoting the objectives of the labor movement in both nations. Accordingly, both organizations hold fraternal associate membership status in the other, and both organizations have a seat on the other's executive council.

International Woodworkers of America

International Woodworkers of America (IWA) was an industrial union of lumbermen, sawmill workers, timber transportation workers and others formed in 1937.

The IWA was formed when members of the Sawmill and Timber Workers’ Union division of the United Brotherhood of Carpenters and Joiners of America voted to disaffiliate their local unions and form their own union. The IWA subsequently affiliated with the Congress of Industrial Organizations (CIO).

The IWA quickly moved into Canada, where it absorbed a number of smaller unions which had formed in the 1930s, and the Lumber Workers Industrial Union, one of the industrial unions of the Industrial Workers of the World. A successful strike and organizing drive in 1946 established the IWA as western Canada's largest union, a position that it has generally held since then.

The IWA was staunchly Democratic, and avoided left-wing politics throughout its history. Most of its members lived and worked in the American and Canadian West. Its membership reached as high as 115,000 in the early 1970s.

In the 1980s, raids, mergers and anti-union actions by employers decimated the IWA's membership. The burgeoning environmental movement also restricted access to public lands, where most old-growth timber existed. As the timber industry lost access to public land, timber companies shed thousands of jobs as well.

In 1987, the Canadian branch of the IWA separated from union, retaining the IWA initials but with the new name Industrial, Wood and Allied Workers of Canada (IWA Canada).

By 1994, the remainder of the U.S.-based IWA had just over 20,000 members. The IWA leadership felt the union was no longer viable on its own, and the IWA merged with the International Association of Machinists (IAM) on May 1, 1994. Today, the IWA is the Woodworking Department of the IAM. IWA Canada remained an independent Canadian union until 2004, when it merged with the United Steelworkers.

Mariano S. Bishop

Mariano S. Bishop (November 14, 1906 – January 2, 1953) was a labor organizer and union leader who served in turn as principal Organizer, Director, and Executive Vice President of the Textile Workers Union of America.

Meat packing industry

The meat packing industry handles the slaughtering, processing, packaging, and distribution of animals such as cattle, pigs, sheep and other livestock. Poultry is not included. This greater part of the entire meat industry is primarily focused on producing meat for human consumption, but it also yields a variety of by-products including hides, feathers, dried blood, and, through the process of rendering, fat such as tallow and protein meals such as meat & bone meal.

In the U.S. and some other countries, the facility where the meat packing is done is called a slaughterhouse, packinghouse or a meat packing plant; in New Zealand, where most of the products are exported, it is called a freezing works. An abattoir is a place where animals are slaughtered for food.

The meat packing industry grew with the construction of the railroads and methods of refrigeration for meat preservation. Railroads made possible the transport of stock to central points for processing, and the transport of products.

National Association of Broadcast Employees and Technicians

The National Association of Broadcast Employees and Technicians (NABET-CWA) is a labor union representing employees in television, radio, film, and media production. A division of the Communications Workers of America (CWA), NABET represents about 12,000 workers organized into about 35 local unions ("locals").

The union was first organised in 1934 as the Association of Technical Employees (ATE), at first covering employees involved in network television and radio; the union was created by NBC as a way to prevent its own workers from joining the International Brotherhood of Electrical Workers. The ATE would soon expand to other radio networks, and by 1937, ATE also included independent radio and television stations. In 1939 the ATE achieved a union shop clause.

The union's name changed to NABET in 1940 and was affiliated with the Congress of Industrial Organizations (CIO) in 1951. In 1952 Canadian radio, television and film workers were entered into the NABET fold. In 1965, NABET expanded to include workers in the film industry.

In 1968, Canadian NABET locals achieved local autonomy followed in 1974 by full autonomy. These locals are affiliated with Unifor.

In 1994, NABET merged with the CWA and changed its name to NABET-CWA.

Its current officers are Sector President Charles G. Braico and Sector Vice President Lou Marinaro, both elected on June 6, 2015.

National trade union center

A national trade union center is a federation or confederation of trade unions in a single country. Nearly every country in the world has a national trade union center, and many have more than one. When there is more than one national center, it is often because of ideological differences—in some cases long-standing historic differences. In some regions, such as the Nordic countries, different centers exist on a sectoral basis, for example for blue collar workers and professionals.

Among the larger national centers in the world are the American Federation of Labor-Congress of Industrial Organizations and the Change to Win Federation in the USA; the Canadian Labour Congress; the Trades Union Congress (TUC) in Britain; the Irish Congress of Trade Unions; the Australian Council of Trade Unions (ACTU); the Congress of South African Trade Unions; the Dutch FNV; the Danish, Norwegian, and Swedish LO; the German DGB; the French CGT and CFDT; the Italian CISL, CGIL and UIL; the Spanish CCOO, CNT, CGT and USO; the Czech ČMKOS; the Japan Trade Union Confederation RENGO; the Argentinian CGT and CTA; the Brazilian CUT, and so on.

Many national trade union centers are now members of the International Trade Union Confederation, although some belong to the World Federation of Trade Unions.

Philip Murray

Philip Murray (May 25, 1886 – November 9, 1952) was a Scottish-born steelworker and an American labor leader. He was the first president of the Steel Workers Organizing Committee (SWOC), the first president of the United Steelworkers of America (USWA), and the longest-serving president of the Congress of Industrial Organizations (CIO).

Steel Workers Organizing Committee

The Steel Workers Organizing Committee (SWOC) was one of two precursor labor organizations to the United Steelworkers. It was formed by the CIO (Congress of Industrial Organizations) on June 7, 1936. It disbanded in 1942 to become the United Steel Workers of America.

Textile Workers Union of America

The Textile Workers Union of America (TWUA) was an industrial union of textile workers established through the Congress of Industrial Organizations in 1939 and merged with the Amalgamated Clothing Workers of America to become the Amalgamated Clothing and Textile Workers Union (ACTWU) in 1976. It waged a decades-long campaign to organize J.P. Stevens and other Southern textile manufacturers that achieved some successes.

United Automobile Workers

The International Union, United Automobile, Aerospace, and Agricultural Implement Workers of America, better known as the United Automobile Workers (UAW), is an American labor union that represents workers in the United States (including Puerto Rico) and Canada. It was founded as part of the Congress of Industrial Organizations (CIO) in the 1930s and grew rapidly from 1936 to the 1950s. The union played a major role in the liberal wing of the Democratic party under the leadership of Walter Reuther (president 1946-70). It was known for gaining high wages and pensions for auto workers, but it was unable to unionize auto plants built by foreign-based car makers in the South after the 1970s, and it went into a steady decline in membership; reasons for this included increased automation, decreased use of labor, movements of manufacturing (including reaction to NAFTA), and increased globalization.

UAW members in the 21st century work in industries as diverse as autos and auto parts, health care, casino gambling, and higher education. The union is headquartered in Detroit, Michigan. It claims to have more than 391,000 active members and more than 580,000 retired members in over 600 local unions, and claims to hold 1,150 contracts with some 1,600 employers.

United States v. Congress of Industrial Organizations

United States v. Congress of Industrial Organizations, 335 U.S. 106 (1948), is a US labor law decision by the United States Supreme Court, which held that a labor union's publication of a statement that advocated for its members to vote for a certain candidate for Congress did not violate the Federal Corrupt Practices Act, as amended by the 1947 Labor Management Relations Act.
