Autoworkers in Oshawa unionized the General Motors plant in Oshawa in 1937 after a bitterly fought strike that pitted them against a rabidly anti-union government, hostile press and GM corporation. It was a major turning point in Canadian labor history. Crucial factors contributing to the strike' s success include the historical background of working-class struggle in the community, patient and courageous prior organizing by Communists, the engaged leadership of rank-and-file GM workers, and the solid support of the United Autoworkers International Union. The author focuses on the voices and actions of rank-and-file workers and on the day-to-day events, many of which have been misunderstood or misinterpreted. He takes down the false narrative the the autoworkers in Oshawa were on their own without support from the UAW\CIO leadership.
