It's a weird cultural thing to some degree, IME. I spent the last couple years either on sabbatical or in a (regrettably) undemanding job, and I've now come back to a pretty challenging high-pressure work environment, where I'm almost getting more responsibility and difficult work thrown at me than I can handle. I absolutely love it, and I do deal with some level of stress, but I've grown to expect a certain amount of me time, and I work a hard 8 hours a day. I know there are people whose workplaces explicitly care about butt-in-seat time and expect after-hours availability, but I know many, many people whose workplaces don't but that still find themselves working all the time. I really don't know how to account for this: all of my friends who do this seem pretty miserable about it, and none of them are in a position where they're so resource-constrained that they need to squeeze more dollars out of their income.
