I always remember as a teenager reading Paula Yate's book & her stating most women's jobs were pretty dull & menial so they really should stay home with their kids. I always thought it was a suspect viewpoint & it certainly didn't seem to make poor old Paula happy.
Treacle your job sounds hellish, but honestly not all employers are like that. I have had bad employers, so I sympathise, but there are good ones out there.
Yes, many jobs have a dull element, but I have never found anything as exquisitely boring as endlessly pushing a child on a swing
However, like many women, I have paid my dues with child rearing.
I have made many mistakes, but the one thing I did right was always keeping a toe in the world of work, even when I was pretty much full time at home, with a bit of freelancing. I would advise any woman to try and do something, even if just an hour or two a week - it really can pay dividends later.
I am delighted and grateful I have been able to reignite my career & look forward to the next few years of focussing on that, as my DDs are busy moving up and away.
