Traffic Slowdown at Miller and Dix Roads during Ford Rouge Plant Strike, Dearborn, Michigan, 1941

Ford Motor Company was the last major auto manufacturer to be organized by the United Auto Workers. On April 1, 1941, workers at Ford's Dearborn, Michigan, Rouge Plant -- reacting to anti-union firings and violence -- shut down the factory. After a turbulent ten-day strike, Ford agreed to union demands. Here, workers and their cars block access to the plant as onlookers watch.
