i so agree with caligula's point about the organisation of work impacting on all aspects of society.
i'm now a SAHM. when DD was born four years ago i gave up a full time job which paid £100+K and took up a different full time one which paid £27K.
My husband started his own business round about the time of DD's birth. in order for that to succeed, he had to work all hours and was largely unable to help with childcare, in particular nusery drop offs and pick ups.
the reason for my change of jobs: we live about an hour down the motorway from where i worked in job 1, longer if the traffic is bad. i would leave the house at about 6.45am and get back at 8pm. nurseries aren't open for all those hours which meant that the only childcare which would have worked for us was a full time nanny (live out, we don't have room for a live in). to be honest i didn't even try to find a nanny who would work those hours either, although i'm sure they exist. i lost my nerve at the thought of leaving DD alone all day with a nanny. i couldn't continue with job 1 but we needed some income while my husband got his business going, hence job 2.
theoretically, i could have continued with both of those jobs on a part time basis. however, in the case of job 1, my relative seniority would in my view have made that impossible. i was often the sole contact for key business projects, often dealing with the States and the business's need for my knowledge and expertise wouldn't just have stopped on my days off/if i went home early. as it happens, i did work part time from home for this employer for 5 months after DD was born and it was pretty much a nightmare for those reasons. i recall walking round the garden trying to do a conference call on my day off with DD overdue for a feed and in my arms, praying that she would keep quiet long enough for me to finish the call.
job 2 was stricly 9 to 5 and local, so i could manage nursery drop offs and pick ups. i could have continued there part time but the logistics of transport make it nigh on impossible. (there is no parking at work and i would need to use a park and ride. so my morning would be - drop DSs at nusery local to our house, drive into town to take DD to school, drive back out of town to the park and ride, get the park and ride back into (a different part of) town to work. and in reverse at night. plus, rather crucially, i'd be working at a financial loss given the scale of nusery fees. for me it doesn't stack up, hence SAHM.
which in fact i'm extremely happy about!!!
but look at what has taken me out of the workplace: a husband who although willing is unable to take responsibility for dropping off/collections of children (because we think/hope that his income is going to be worth the hours he puts in); originally, too long a working day - a combination of a long commute plus having a job which genuinely made flexible working difficult/impossible - but probably enough money to fund childcare if i wanted to work full time; then, having got rid of the long day by downshifting, not enough money to cover the childcare.
i don't know what your experience is, but there is a pattern emerging amongst my female friends who have children and reasonably highly paid jobs. almost to a women they have husbands who work long hours and earn as much/more than them. my friends have all gone part time after having children. they are lucky that the jobs pay well enough to make part time financially viable but inevitably there are fault lines appearing at work. they need to finish on the dot to pick up from nursery/childminder/relieve nanny; those with children at nursery/childminder have to take time off when the children are sick; other people need to pick up the slack; they're all thinking they're going to have to give up entirely when their children go to school.
so here is a clutch of women, who can't be entirely unrepresentative, all university educated and beyond, all having had senior jobs, all about to give up, probably permanently. think of the cost of educating us all!! does this matter? should we have gone into something different in the first place, something that lent itself to flexible working? is there such a job?????
