United States strike wave of 1945–1946

The US strike wave of 1945–1946 or great strike wave of 1946 were a series of massive post-war labor strikes after World War II from 1945 to 1946 in the United States spanning numerous industries including the motion picture (Hollywood Black Friday) and public utilities. In the year after V-J Day, more than five million American workers were involved in strikes, which lasted on average four times longer than those during the war.
