I see a fair amount of sentiment in this thread that's averse to what from my perspective is a very light on-call schedule. My former employer was a manufacturing plant that operated 24/7. The engineers (not software, mostly chemical, mechanical, and electrical), all of us carried pagers at all times and were expected to phone in within minutes of being paged, any day or night. A bad enough incident would require you…
If I have to option to not do a bad thing (even if it is only minimally bad), then why shouldn't I pursue that option?
If you don't mind doing the bad thing, then you should definitely take advantage of that. But probably shouldn't try to convince other people that the bad thing isn't bad. 1) It reduces your own advantage of willing to do the bad thing which you are hopefully converting into money. And 2) its end game is making people do something they don't enjoy without reason or compensation, which seems bad.
