February 11th
National White Shirt Day

White Shirt Day honors workers who participated in the Flint Sit-Down strike that led to the unionization of the entire U.S. auto industry. The Flint Sit-Down strike began on December 30, 1936, at a General Motors Corporation plant in Flint, Michigan, and ended 44 days later on February 11, 1937. In 1948, Bert Christenson, a member of the United Auto Workers (UAW) union, started the tradition of wearing white shirts every February 11 as a way to commemorate the end of the Flint Sit-Down Strike.
