It depends in part on the intangibles of the specific job.
Back in January of last year...geez, a year already?...I got an internship at a small company, and had a chance to get a feel for the place. The owner actually gives a damn about his employees, and his ideals in that respect are accordingly filtered down through upper management.
They don't work the employees to death like some large corporations. The GE plant nearby has a word I hear frequently associated with it: "burnout." Long workweeks, long hours, weekend workdays, etc.
Where I'm at, assuming everything's getting done on time, me and a few of the other engineers will still be in the office at 5:00 on a Friday, and the company president will stop in to just do his usual deadpan delivery of, "It's 5'o'clock. Friday. Go home. Have fun. Do something else."
Problem is....I rather enjoy the work, most of the time. It's kind of like doing my hobbies, except with some deadlines here and there, but with a considerably larger budget than I have, and useful, practical goals for the projects (again, most of the time).
I don't know if you'll be afforded such a luxury of a good preview of the work environment at a prospective employer, but just from someone who's worked not only at retail and temp jobs, where workers are usually viewed as disposable annoyances, this is a drastic change. And nothing beats having a job where quitting time comes and you think, "Oh darn it...ffffffine, I guess I'll go home," just because the work is entertaining or interesting. (I've heard rumors that a "girlfriend" of some sort might provide some substantial motivation to leave said interesting job on time, but I have yet to confirm this with real-world test data.)
So anyway, the pay here is not top-notch. It's on the lower end, if anything. But we've got a nice benefits package, an owner who pushes for more and more employee benefits, usually to the point of making the CFO huddle in a corner, shivering and crying, and generally a decent, relaxed work environment.
Those retail and temp jobs, I was usually thinking, "Is it quitting time yet?" as I was clocking in for the day. And I'd end the day stressed and tired. The only part of going to work that I dread now is the fact that it starts at 8am.
Oh, and there are random days when free pizza or donuts will appear in the breakroom.
