> your manager ... asks if you would like to join the rotation.

I don't think I've worked anywhere in the last decade where I was not part of the on-call rotation. It's been obligatory, maybe because I've worked at small-to-medium sized companies. I'm on call this week, in fact.

On-call weeks are my least favorite though. It's always nice when my rotation includes a holiday because our users are only active during normal business hours, so we never have issues when everyone's out of the office.

I was on-call physical IT for a hospital system and I developed PTSD out of it.

Over ten years later, I still feel the effects. Every notification, every ring just brings life to a stop, for just a few moments.

I can agree, OP: on-call rosters change your life.

It all depends on a software one is supposed to be responsible for. For some, it'll at most a few pages a year, for others it'll be constant pain having to deal with problems.

Oncall is complete bullshit and the fact that we have standardised this without Additional pay has greatly affected my life working in big tech.
