My parents were teachers and I remember them marking after school and some weekends. My wife is now a teacher and she has after school meetings at least once a week, spends hours marking every night and weekends, plus a lot of her holiday preparing new lessons and admin. Contractually she has the exact same hours and holidays my parents had but her life is nothing like theirs.

For myself I'm a scientist and people have worked long hours since I was a student - but it used to tail off as people got into their 30s and became more secure, maybe got a stable position, teaching, and students of their own. Now this seems to have been pushed back to an ever receding horizon and people work long long hours competing to get the next grant or next placement, to keep their heads above water right up till retirement. Of course academics all contractually work a 40 hour week.

I guess its anecdotal but I see the same sort of things amongst my friends in tech and pharma. Their laptops and mobiles have enslaved them.

Maybe I was blind to it when young but I don't remember my parents generation - their friends, my relatives working like that.
