Labor union

Workers had organized informally for centuries, through guilds, mutual aid societies, and ad hoc coalitions that formed around specific grievances. What changed in the early nineteenth century was the legal framework. Britain's Combination Acts of 1799 and 1800 explicitly criminalized collective bargaining, treating any organized effort by workers to negotiate wages or conditions as a conspiracy. The repeal of these acts in 1824, followed by clarifying legislation in 1825, created the first legal space in which unions could exist without their members facing imprisonment.

The formalization accelerated. In 1868, the Trades Union Congress was established in Manchester, creating a national body to coordinate union activity across industries. Britain's Trade Union Act of 1871 granted unions legal status for the first time, protecting their funds from seizure. In the United States, the trajectory was different but parallel. The Knights of Labor, founded in 1869, organized across skill levels and racial lines before declining in the 1890s. The American Federation of Labor, established in 1886 under Samuel Gompers, took a narrower approach, organizing skilled workers by craft.

The Wagner Act of 1935, formally the National Labor Relations Act, established the legal right of American workers to organize, bargain collectively, and strike. Union membership in the United States peaked at roughly thirty-five percent of the workforce in the mid-1950s. By 2024, that figure had fallen to approximately ten percent, with private-sector membership at six percent. The decline tracks closely with the erosion of the postwar economic compact between employers and workers.
