The War Ends For General Motors and the Strike Comes

When World War Two ended, the car long known for style and manufacturing quality, Buick, was more than ready to pick up where it left off. Buick was a best seller for GM after it's budget priced Chevrolet.

Although 1945 saw peace come to the world it was another thing at home. By the end of 1945 pent up demand for new civilian automobiles meant that America's automakers would be able to sell new cars as fast as they could build them.

This was not lost on the union leaders. The United Auto Workers under president Walter Reuther demanded immediate pay increases for GM auto workers totaling some 30%. This demand was refused as well as Reuther's request to see their books. What resulted was a strike hit General Motors in November of 1945. This of course put a roadblock up for Buick which wanted to resume where it left off in February 1942.
