The movement for a shorter workweek was once the defining feature of the labor movement in the United States, but that movement was largely displaced by the new corporatist structure of organized labor in the post-New Deal era. Labor's Time examines the structural transformation of organized labor and traces its influence on the decline of the shorter hours movement. Focusing on the internal union politics of the influential United Automobile Workers and Local 600, its local union at Henry Ford's massive "River Rouge" factory, Jonathan Cutler demonstrates how an all-but forgotten, interracial movement for a shorter workweek during the 1950s and 1960s became a casualty of an increasingly top-heavy union bureaucracy that lost touch with the desires, fears, and aspirations of rank and file workers and dug its own grave in the process. Cutler first examines the political context in which the shorter hours movement emerged within Local 600 in the 1940s. He then chronicles the attempts by Walter Reuther, the head of the UAW, to suppress the demand for thirty hours' work and forty hours pay within the union.
