How did shifting workforce demographics contribute to the dramatic changes that occurred in the US labor force and industry during and immediately after World War II?

Minorities and women were allowed into the workforce leading to rights movements after the war.

The war took white, men out of the workforce to fight. This allowed for minorities and women to take those jobs. By gaining access to employment, these groups enjoyed more freedom than experienced before World War II.

Following the war, when white men came back to claim their jobs, those employed during the war refused to take a backseat to white men. Minorities fought for rights to equal education, the end of segregation, and the creation of laws protecting their civil rights. Women also fought for the right to access education and professions as well as the right to birth control.
