I find it shocking that they expect remote workers on a 7 hour difference timezone to start working extremelly early in the morning and work through the night if needed.

I find it also strange to expect someone to be reachable outside their normal working hours without being on call and properly compensated for their availability.

It sounds like these companies are taking advantage of the desire these engineers have for better projects without leaving their countries to for them to work in less than human conditions.

Amanzingly they only mention european countries where the labour law is said to work better.

In you experience, are these practices common/ legal or is an isolated case ?

If they mention these things on their public web page, what else can be going on.
