Teamster Power tells the story of how the men and women of Minneapolis Teamsters Local 574 and their class-struggle leadership used the power they had won through three hard-fought strikes in 1934 to extend union power to cities throughout the Upper Midwest, help the unemployed organise and fight for jobs, combat employer frame-ups and assassinations, and launch an eleven-state campaign that brought tens of thousands of over-the-road drivers into the union.
