One left-led union they discuss is also the subject of Howard Kimeldorf’s Reds or Rackets? The Making of Radical and Conservative Unions on the Waterfront. Kimeldorf analyzes the stark differences between two mostly male dockworkers’ unions, one on the East Coast and the other on the West Coast, that developed during the same period, the era of the CIO. On the East Coast, where workers and their leaders fought chiefly for money and other material gains, official corruption became legendary; bribes served to buy off the Eastern unions for decades. On the West Coast, where the unions fought for control of production, that is, for the right to negotiate rules governing safety, hours, and similar issues, bribes didn’t work: Money wasn’t what these workers were looking for. The West Coast’s Wobbly-inclined base produced a leader, Harry Bridges, who was openly a socialist. Bridges and the West Coast workers routinely engaged in strikes; they had to; their demands were substantial and the employers weren’t easy to beat. Kimeldorf concludes that the endless class struggle in which the West Coast workers engaged resulted in high-quality contracts that cemented a high level of participation, active membership, and a strong relationship between the rank and file and the union leaders. He demonstrates that this left-wing leadership showed superior skill in every aspect of running a union, and notes that members routinely reelected socialists to leadership positions, even though their own politics were not uniformly left-wing, but instead quite diverse.
