I'd question 'working class' now if you can afford to move jobs without being concerned about being paid for a year.
It think its reductive to say these are straw women, my point is that although the job was no-one by default, I think it's wrong to apply for a job you're only going to do for a few months when that opportunity could go to someone else. This sounds like a standard management role.
Fair enough if op doesn't agree but there it is. I don't think it will be fair to claim you've worked somewhere and have x experience when you've only worked there for 3 months, barely past probation.
Also, I don't think its very nice to sneer at the 'poor little' shop workers or people that are in the service industry. There's a massive difference in how women are treated in difference sectors and i think its worth discussing even if you don't.
Professionally I would feel the same if a man did it which as people have pointed out on this thread is entirely possible with our current laws.
Also, no-one said anything about waiting to get pregnant, op is already 7 months pregnant ... that was the question.
OP if you're happy doing what you're doing then good luck to you - like i said you're clearly driven.
Having an opposite view doesn't make me mad, thank you.
