We have a team distributed over many time zones so we have to send messages to each other at "off hours". Thankfully we have a good understanding that this is for the convenience of the sender and the receiver can reply the following day.

I have one team member in Quebec and the way they handle this seems to make more sense than Portugal's. Basically, the employees have the right to refuse 'overtime'. So, the boss can message them, but they cannot be penalized for not responding.
