The Flint sit-down strike ends when General Motors recognizes the United Auto Workers trade union.

The 1936–1937 Flint sit-down strike, also known as the General Motors sit-down strike, or the great GM sit-down strike, was a sitdown strike at the General Motors plant in Flint, Michigan, United States. It changed the United Automobile Workers (UAW) from a collection of isolated local unions on the fringes of the industry into a major labor union, and led to the unionization of the American automobile industry.

General Motors Company (GM) is an American multinational automotive manufacturing company headquartered in Detroit, Michigan, United States. The company is most known for owning and manufacturing four automobile brands: Chevrolet, Buick, GMC, and Cadillac, each a separate division of GM. By total sales, it has continuously been the largest automaker in the United States, and was the largest in the world for 77 years before losing the top spot to Toyota in 2008.

The United Auto Workers (UAW), fully named International Union, United Automobile, Aerospace and Agricultural Implement Workers of America, is an American labor union that represents workers in the United States and southern Ontario, Canada. It was founded as part of the Congress of Industrial Organizations (CIO) in the 1930s and grew rapidly from 1936 to the 1950s. The union played a major role in the liberal wing of the Democratic Party under the leadership of Walter Reuther. It was known for gaining high wages and pensions for automotive manufacturing workers, but it was unable to unionize auto plants built by foreign-based car makers in the South after the 1970s, and it went into a steady decline in membership; reasons for this included increased automation, decreased use of labor, mismanagement, movements of manufacturing, and increased globalization. After a successful strike at the Big Three in 2023, the union organized its first foreign plant (VW) in 2024.
