I'm in Europe, and work for an American company. After a few issues in production, they tried to implement an on-call requirement for employees to check the alerts during their out of work hours (5am to 10pm or something stupid like that). I just reminded them that my country has the "Right to disconnect" law, which protects us from having to work outside our required hours.

They changed it to volunteer basis. I refuse to volunteer (because my off time is my time).
