Fook dat.
Unless you're taking home a six-digit paycheck, it's not worth working those kind of hours.
You've got a family, man! Get a grip on *why* you go to work - so that you can provide for the clan, and have enough left over to do the fun stuff you want to do.
Perhaps you should emigrate to the UK - over here, if we work more than 37.5 hours a week, we put it down as overtime :-)
Seriously though, the UK employee is somewhat more protected than their US counterparts. We have legislation covering maximum weekly hours (with a *very few* exceptions, no-one can be forced to work more than 48 hours a week), legislation covering unfair dismissal (and an established tribunal process), health and safety (you need a weirdass chair to stop your back hurting? You got it) etc etc.
It's the nuclear option, to be sure, and in the current job market and economic climate, risky, but still...
Another alternative would be to get a job in the US working for a UK company and then get transferred to the land of good telly and decent beer. And rain :-)
