what the article (and, I would guess, the research she refers to ) totally fail to take into account is that most women (unlike most men)do not have the third option - ie that of working whilst leaving their children in the care of a parent. they choose between working (whether part or full-time) and using childcare, or not working. this is a stark 2-way choice that hardly any men at all face. and it's faced with that particular two-way choice that a lot of women say they'd like to work p-t.
if (in the research) they had the option of leaving their children with their father I'm sure many would give different answers.
the article, and the research, also fail to consider what men/fathers want. because the vast majority I know would also favour part-time working.
when the pay gap closes and when p-t/flexible working arrangements become as normal for men, as for women, then men and women will face the same choices. and I might stop hectoring.
that article has really pissed me off.
