One of my grandmothers was a housemaid until she married in 1901 at the age of 23. She didn't work again, but brought up her niece and her own children.
My other grandmother never worked at all. The 1911 census says she is 'at home' and that is how it stayed. Her younger sister did work, as a welfare officer, until she married in 1945.
My mother was just 20 when she married in 1940. She had been moved from her existing office job to do war work and she carried on until 1946, when my Dad came out of the army and her job disappeared anyway. She never worked again.
My aunt on the other hand, my Dad's sister, was widowed at the age of 22 and went back to work in a knitwear factory as soon as she could. She then re-married and had another child, and went back to work again. She actually worked pretty much straight through from the 1930s until retirement in 1976.
I got married straight after graduation, so by the time I hit the job market in 1977, I was already married. That did not seem to affect anything day to day, but when I got pregnant in 1982, I was the first woman employed by that provincial law firm to take maternity leave, which caused all sorts of consternation amongst the partners. There were a couple of part-timers who had left to have children and subsequently come back, but I was the first to protect my job and my rights.
