I hate that in the past I've worked in an environment where overtime or week-end work was a badge of courage. Where the pager was rotated and the holder expected a page every night at some point. And this was commonly accepted. People didn't question whether the pager should have been able to go a week without ringing... they were used to knowing it would go off within the next 12 hours.
Of course, the company didn't require overtime... it didn't condone burning out... but we also didn't force someone who stayed up until 3 am to come in late (or not at all) either. Where does the line between volunteering and demanding begin/end?
Well, here's a post that I like... it's a debate I've poked at for over 5 years and homebrutrout says the piece very well.
