Answer:
During WWI, many jobs were left vacant because men left to fight the war. In order to keep these industries running, the jobs were often taken by women. This was unusual at the time, and it gave them a taste of independence. When the war was over, many of them were not happy to return to their previous position as housekeepers. They wanted to remain involved in the public sphere and the running of the country. One of the ways to achieve this was by winning the right to vote. Their role during the war also helped them demonstrate their abilities to contribute as members of society.
