True.
As men left jobs open when they went to fight in the war, women had to take up more positions in the workforce. When the men came back, they needed their jobs back, and women weren't happy about being pushed back out of/kept from the workplace. This incited a new sense of unity and purpose among women, and began the fight for gender equality in the workplace(and later on helped fuel the fire for more women's rights campaigns).
Hope this helps! :)
