Many people work shifts, it’s quite normal.

What seems to be unique in American companies is you’re expected to work shifts or nights but also work m-f 9-5 at the same time, which is really weird.

Same with of call, if you get called at 3am on an on/call rota for a specialised third line escalation many companies still expect you to work the next day, and they might not even pay you for being on call?!
