I have a feeling it was only in the late 80's that women coukd be married in Army. They certainly couldn't be mothers then .
No, we could be married earlier than that. My mum had to leave the air force pregnant with me, and that carried on with women in the military until around... 1990? During my time you had to leave before 12 weeks so no maternity pay, nothing.
But pp is right: working class women have always worked so what we are talking about here is pretty much middle class career type jobs. And of course there were exceptions, after the 2nd world war when many women who had done some pretty gruelling jobs in things like the steel industry (for low wages) and had to give them up when the men came back, of course they started to push back against this kind of thing.
I've heard before about some jobs in the civil service making exceptions for certain jobs, but usually having a child put paid to that. My mum always worked, often only part time, when i was growing up, at one point her hourly salary was quite a lot more than my father's - although he did earn more as he worked full-time. She had a proper trade though and worked in a drawing office. Back in the 70s she was much in demand and could pretty much work only term-time with the whole holidays off. It was unusual among my friends, though. At most one or two had little cleaning jobs and for a long time women's earnings were considered pin-money.
I think that a lot of us can and should be very grateful to the women who kicked back and made their way in the world of work, some of whom have been mentioned on this thread. And we should definitely not look down on women who had to give up on their dreams and wishes because of biology.
Younger women who watched the Handmaid's Tale have said to me "blimey, when they closed their bank accounts" and hearing how long it took for women to be able to get loans, etc, have been very shocked.
