I used to work for Accenture and that was a frequent 10-12 hour day, travel time on top at an hour each way or working away from home, sometimes more and usually pressured to deliver. Sometimes it was alright if you had a decent project manager, which was most of the time, but occasionally, you worked for someone whose primary concern was his reaching a Senior role ASAP and using the team as the path to get there and all the people skills of walrus.
I'm now self-employed, doing the same job I did before, but minus the stress. I steer my own ship to a degree, work for a major insurance and life company as a contractor, make more money than I did previously (pretty much doubled my take home pay overnight after tax). I work a 7 hour day and anything else goes in as overtime at the agreed rate. The idea I'd work 7 days isn't even on the cards. To my mind, that's not what life's about - work to live, not the other way around IMO.
I'm not stuck in an ivory tower; I realise I'm pretty lucky for now, but time can change anything. My parents worked hard, people these days have to work hard too if they're near the breadline. It's not easy and I'm not claiming it is, but working 7 days solves nothing, gains nothing and damages more than it cures.
EDIT: I make a point of taking holiday as well, no you don't get paid for it, but two and a half weeks off was a better return for me than the money that went unearnt while I was off.
