It happened on October 3rd: UAW goes on strike at Ford plants

On October 3rd, 1961, 120,000 workers at 88 Ford plants in 26 U.S. states (all members of the United Auto Workers) went on strike, following the example of GM workers a month earlier. The latter won substantial wage and benefit improvements, and Ford officials knew they had to provide a comparable package or risk losing their workers to the competition.
