I used to work the night shift handling most off hours issues for a a couple dozen teams. We would occasionally have to call someone, but not that often compared to the alternative. Most of the time it was just to get sign off on what we already planned to do.

When I started people were paid for any hours they worked on-call. By the end, the company changed the policy so on-call was part of base pay. For those who were on-call during the change over, their last year of on-call pay was averaged and added to their salary. For everyone who came after that, they got screwed (that includes me).

Once I changed to the day shift I got called a few times for on-call. Every single time, I documented what I did to fix it, as I did it, and handed it off to the ops team. Or in some cases I automated the fix. I have 0 tolerance for being called in my free time. I don’t care what the boss says my priorities are, if I’m being called at night, stopping that in its tracks is my #1 priority. If I ever get called two times for the same issue, that’s my fault. So far, it’s never happened.
