What were the advantages and disadvantages of war work on women?

Umm well... i don't know about the Cold War but in WW1 and WW2 it gave women more freedom and the right to be more equal like men, even though the pay wasn't the same. A woman could be doing the same job as a man but yet be paid less than him because she presumably wasn't skilled enough. The disadvantages were that men weren't happy in the WW1 the most of women taking over mens jobs so they would basically make it harder for the women to do their jobs properly and do things like hammer their nail draws so they couldn't open them and get on with their job.
