WW1 showed that middle class women were capable of so much more than a life of idleness, wearing restrictive clothing and having the vapours. Many of them rose to the challenge and became nurses, land girls, train drivers and a whole lot more.
My GM was already the breadwinner and ran a ladies' tailoring business. After he returned from WWI, my GF never worked again and became alcoholic. They had six children.
My mother trained as a nurse at a London teaching hospital during WWII and lived in London throughout the Blitz. My mother gave up work when she got married in 1945. I believe there was pressure on women to go back to being full-time housewives after WWII so that they did not take work away from the returning men.
I know many women took on what were traditionally men's jobs during WWII. Some became welders, others drove heavy lorries, I believe Princess Elizabeth, as she was then, learned to drive and maintain a lorry.
