How did life change for women in the united states after world war i started?

Because many men were sent off to war, women took the men's positions in the workplace and so after the war, women had more non-traditional roles at work 

It changed the lives of women a lot. During the War, most men were drafted into the war, which opened up a ton of jobs for women. Women were able to now volunteer/work for the Marines, Army, and Navy and take jobs left behind by men. So, their lives changed because the War gave them jobs and other oppurtuinites.
