How the class-struggle Teamsters leadership in the Upper Midwest organized to fight union busting, racism, and colonial oppression, as they opposed the mobilization of labor behind U.S. imperialist war aims in World War II. How Washington--backed by top AFL, CIO, and Teamsters officials--acted to gag class-conscious workers. The last of four books on the 1930s strikes, organizing drives, and political campaigns that transformed the Teamsters union in Minnesota and much of the Midwest into a fighting industrial union movement. Written by a leader of the communist movement in the U.S. and organizer of the Teamsters union during the rise of the CIO. Indispensable tools for advancing revolutionary politics, organization, and effective trade unionism.
