Haven't got time to read all the posts - sorry if I'm just repeating stuff.
'Working class' women have always and will always work out of the home.
So it's the middle classes who are going to be affected most, plus it will make it more difficult for working class women to aspire to a salaried job with holiday pay, flexible hours etc.
It does look as if the government is trying to do a bit of social engineering here. What strikes me is how they think they can remove whole sections of the population from employment - and deal with the repercussions when?
How do they intend to cope with the stages in a modern (middle class) woman's career, which often follows this pattern: sahm with young children then part-time worker with school-age then full-time when the kids are older or leave school?
If you keep women out of the workforce when their kids are young, they might never get back in at a level appropriate to their qualifications, and will obviously have less experience to offer.
This has implications for education too - why bother to educate girls in nuclear physics if they are going to stay at home??
All we want - all we have ever wanted, and what we fought for - is a flexible working life with good, affordable childcare. This is something that benefits women, men, employers, families and society, and should be a right if we believe at all in equality of opportunity.
We can't let this be taken away if we want a healthy, fair society.
My knee has stopped jerking now.
