That’s what the work profile on your personal phone is for, so you can turn it off when you’re off the clock (or rather if you don’t get paid to be alert)
I left Monday last week after a crash had occurred in prod. Had happened during the weekend because of a colleague fumbling on the Friday. Noticed it Monday morning. Notified the boss who didn’t care much and left for his afternoon off anyway, trusting me to do what i could. Which I did. Stabilised the bleeding, explained others what they had done and what to do, how to mitigate, how to temporise till I was back, then fucked off at 5pm sharp, for one of the best romantic weeks in years. Not a one phone call or message. I had even taken my laptop just in case they were really stuck. Nothing.
