No. A few companies may have toxic expectations from management (and some of the stories here do show people who work for such places); avoid them (quit if you mistakenly end up at one).
But most of this is self-inflicted via tacitly accepting and reinforcing cultural norms that don't actually need to be followed. I've yet to work at a place that attempted to abuse my boundaries once I made it clear I respected them. I.e., "Didn't you see that email I sent last night?" "I did when I got in today", they now know I don't check email after hours. No one wants to 'officially' say "You should have no work life balance; we expect you to be on call 24/7", so just making it clear that you won't voluntarily do it, and will presume that you are always truly off the clock when not at work, means they tacitly accept it.
