hi jimjams, it's me again, your on-line stalker...
you are completely right about how hard it is when you are trying to get established in academia. before my dh got his permanent job, he was juggling three short-term p/t contracts to make ends meet, two in london and one in hull! it is only since he got his permanent job that he has had the flexibility i mentioned. and we were b**y lucky he got a job near london, many academics are working at opposite ends of the country from their partners. oh, and my real bugbear, most earning less than the average graduate starting salary. they really do it for love of the job!
in terms of other careers, i still think there is a presentee, rather than deliverables based, culture which means that working long hours is seen as a sine qua non for advancement. if there were a critical mass of employees including some men, who were prepared to say "no more!" - and take the salary cut of course - i think many bastions of the long hours culture would be forced to change. unfortunately, that seems a long way off.
i'm very lucky at my place, v. supportive bosses etc. plus i have been there ages and "established" myself. my responsibilities have increased twice since i came back from maternity leave, despite reducing my hours. however, it is actually easier for me now that i'm a bit more senior. it's the junior PMs who are trying to make their names and get promoted who bear the brunt of the long hours necessary. i've done all that in my time...
having said that, i frequently work longer hours than my contract, and still work 5 days a week, and i have deliberately chosen that way of working to enable me to maximise what career chances i have left. would not be able to do it without dh's flexible working and willingness to pitch in and do more than 50% of childcare and chores some weeks when i have to work a lot.
will have to see how things go when i start my new role next month, it is going to be more demanding and higher profile (i hope so, that's what they've promised me! hmmm...) so i could end up forced to work a great deal more. we'll see... at least i can say i've tried!
