Trade unions in the United States are organizations formed by workers to negotiate wages, benefits, and working conditions through collective action and representation. Labor organizations in the United States have evolved through interactions among figures such as Samuel Gompers, events such as the Haymarket affair, institutions like the National Labor Relations Board, and movements including the New Deal and the Civil Rights Movement. Contemporary unions operate within federal statutes such as the National Labor Relations Act and under political influences from parties such as the Democratic Party and groups like the Business Roundtable.
Labor organization in the United States traces origins to craft societies and mutual aid groups in colonial cities like Boston and Philadelphia, then to 19th‑century bodies such as the Knights of Labor and the American Federation of Labor. Major episodes include the Pullman Strike and the Ludlow Massacre, which prompted debates in the United States Congress and reforms under presidents including Theodore Roosevelt and Franklin D. Roosevelt. The consolidation of the AFL–CIO in 1955 followed earlier splits with the Congress of Industrial Organizations, while later clashes with employers and federal agencies—such as the Taft–Hartley Act era and decisions by the Supreme Court of the United States—reshaped union strategy. Postwar trends involved public‑sector growth, fading heavy industries in regions like the Rust Belt, and organizing campaigns in sectors linked to companies such as Walmart, Amazon, and airline carriers represented by unions like the Air Line Pilots Association.
U.S. labor organizations range from national federations like the AFL–CIO and Change to Win to industrial unions such as the United Auto Workers and craft unions such as the International Brotherhood of Electrical Workers. Local unions affiliate with state bodies like the California Labor Federation and with international headquarters such as the Service Employees International Union or the International Brotherhood of Teamsters. Membership trends diverge between the private sector, with employers including General Motors and United Parcel Service resisting unions, and the public sector, where bodies like American Federation of State, County and Municipal Employees and National Education Association maintain higher density. Internal governance often features elected executives, trustees, and bargaining committees modeled on structures used by unions such as the United Steelworkers and the Transport Workers Union of America.
The legal regime for labor relations centers on statutes and agencies including the National Labor Relations Act, the National Labor Relations Board, the Taft–Hartley Act, and the Labor Management Reporting and Disclosure Act of 1959. Judicial interpretation by the Supreme Court of the United States in cases involving unions, employers such as McDonald’s Corporation, and agencies has defined rights for organizations like the Teamsters and the American Federation of State, County and Municipal Employees. State laws, including so‑called "right‑to‑work" statutes enacted in states such as Texas, Florida, and Michigan, affect dues and agency fee arrangements for locals affiliated with federations like the AFL–CIO. Collective bargaining frameworks are also shaped by federal policy from administrations such as those of Ronald Reagan and Barack Obama and by oversight from agencies like the Occupational Safety and Health Administration.
National federations and large unions include the AFL–CIO, Change to Win, Service Employees International Union, American Federation of Teachers, National Education Association, United Steelworkers, United Auto Workers, International Brotherhood of Teamsters, and Communication Workers of America. Sectoral and occupational organizations such as the International Brotherhood of Electrical Workers, Ironworkers, Sheet Metal Workers’ International Association, and International Longshore and Warehouse Union represent workers in construction, manufacturing, and ports tied to employers such as General Electric and ExxonMobil. Public‑sector unions like American Federation of State, County and Municipal Employees and Fraternal Order of Police negotiate under different legal regimes and pension arrangements affected by entities such as the Federal Labor Relations Authority.
Collective bargaining practices vary across industries with negotiation examples involving companies like Ford Motor Company, Delta Air Lines, and UPS and union counterparts such as the United Auto Workers and the Air Line Pilots Association. Strikes and lockouts—historically seen in events like the UAW 1936–37 sit‑down strike and the Air Traffic Controllers Strike of 1981—remain tools, while grievance arbitration and contracts enforce terms negotiated by locals, regional councils, and international unions. Labor relations professionals work within frameworks set by the National Labor Relations Board and corporate counsel from firms associated with employers such as Amazon and Walmart, with outcomes affecting pension plans tied to trustees from groups like the Laborers' International Union of North America.
Recent decades have seen declining union density amid globalization affecting companies like General Motors and Boeing, court rulings from the Supreme Court of the United States, and legislative changes in states such as Wisconsin. Unions have pursued new strategies: organizing in the service sector at employers like Starbucks, partnering with advocacy groups like Service Employees International Union campaigns, and engaging in political action committees that interact with the Democratic Party and labor allies such as House Democrats. Challenges include automation impacting sectors tied to Amazon and Tesla, Inc., internal governance controversies exemplified by past disputes in the International Brotherhood of Teamsters, and competition among federations like AFL–CIO and Change to Win. Labor’s influence on policy continues through lobbying in Washington, D.C., endorsements in presidential campaigns involving figures such as Joe Biden, and coalition work with movements including the Fight for $15 and the Occupy Wall Street movement.
