In 1949 and 1950, the Congress of Industrial Organizations (CIO) expelled many left-wing unions, representing 750,000 workers, because they were supposedly Communist-dominated. This collection of previously unpublished essays explores the history of those eleven left-led unions. Some essays consider specific aspects of several unions--the Longshoremen, the United Electricians (UE), the Fur Workers, and the Food and Tobacco Workers--while others take up the impact of the federal government's and the Catholic church's anticommunism upon the unions as a whole. This collection also addresses central domestic issues of twentieth-century America: race and government policy in the shaping of trade unionism; the impact of anticommunism and the cold war on race relations and working conditions; and the short- and long-range impact of the expulsions upon the labor movement. With groundbreaking essays that also concern the post-World War II period, Southern workers and workers in non-basic industries, this book will appeal to students of radicalism, race relations, anticommunism, and labor history.
