Well... It does, I work for an US based company but from Europe, they expected me to be available almost 24/7 and extra hours are "part of the salary" That's illegal in my country, as soon as I mentioned "Illegal" the discussion ended. Also If I accept to take any extra hours there are limits to that and I can't start working in the next 10 hours (we assume that ppl need rest and sleep).

I think is important to realize that ppl need to rest and have a life outside work and not to see workers as a disposable utility, and as a modern society we need to protect others from the power imbalances.
