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 labour 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.

Truth Be Told takes down the long-accepted?but false?narrative espoused by Irving Abella that the Oshawa workers were "on their own" without significant support from the UAW/CIO leadership and that they would have been better off not to organize under the banner of an international union. It also shows how that narrative fails to grasp the degree to which class struggle organizing principles were crucial to the strike's success.

A true understanding of the 1937 strike provides valuable lessons for people seeking to revive the labour movement today.
