I think you have a poor understanding of what most of the world looks like. Most people on the planet exist in tenuous circumstances which do not allow them to simply go find another job, let alone an employer that isn't abusive, etc. The luxury of being able to worry about these things and take meaningful action to achieve them is truly a recent phenomenon that is not widely distributed.

> Nope - A large portion of the world works like this. If you work for a place which demands you work all of the time, you either work for an abusive employer, or you get paid a lot of money to be at their beck and call.

If you mean that most employers are abusive then yes. That’s why there are laws like this one. Non-abusive employers can ignore it because they were already doing the right thing.

> find another job

See the problem is that if labour laws didn't protect people, then everyone would be constantly under the stress of having one foot out the door and having to look for another job at the drop of a hat. Workplace productivity would plummet and the economy be quickly be tanked

There were no weekends before labor movement fought and got it..
