The longest (November 1945 to March 1946) and the most significant strike was the United Automobile Workers (UAW) strike against General Motors.
From November 21, 1945, until March 13, 1946 (113 days), CIO's United Automobile Workers (UAW), organized "320,000 hourly workers" to form a nationwide strike against the General Motors Corporation, workers used the tactic of the sit-down strike. It was "the longest strike against a major manufacturer" that the UAW had yet seen, and it was also "the longest national GM strike in its history". As director of the UAW's General Motors Department (coordinator of union relations with GM), Walter Reuther suggested to his colleagues the idea of striking the GM manufacturing plants with a 'one-at-a-time' strategy, which was "intended to maximize pressure on the target company." Reuther also put forth the demands of the strikers: a 30 percent increase in wages and a hold on product prices. However, the strike ended to the dissatisfaction of Walter Reuther and the UAW, and the workers received only a 17.5-percent increase in wages.
