Gigantic struggles: the battle to build the United Automobile Workers after the sit-down strikes, 1937–1945

This article examines the struggle to build the United Automobile Workers in the years after the sit-down strike of 1936–37 in Flint, Michigan. The strike, which historian Sidney Fine has called ‘the most significant American labor conflict in the twentieth century,’ has secured the lion’s share of scholarly attention. While it was very important, much remained to be done to make the UAW an institution that represented almost all American autoworkers. At the time of the strike, only 10 percent of GM’s 47,000 Flint workers belonged to the UAW, while much of the industry was unorganized. This article changes the focus, examining the struggle to build the union after the strike. In this period, the union faced bitter internal divisions, ongoing corporate opposition, patchy membership levels, and economic instability. It struggled to establish itself, and internal records – especially overlooked executive board minutes that are mined here – reveal considerable vulnerability and instability. While the UAW made progress between 1937 and 1941, it was in World War II that it solidified itself nationally, helped by favorable bargaining conditions. Even then, it faced ongoing leadership divisions and rank and file disaffection. Building the union took time and deserves closer interrogation.
