At least in France, the general work legislation is generous enough that people in the industry don't feel the need to unionize. We've got 5 weeks holidays per year, plus additional ones if your work contract has more than 35hours of work per week.
Needless to say, burnouts are pretty rare. When they do, it's mostly because of toxic management which can't fire you because of legislation, so they just make your life miserable until you snap. I've also seen it happen in some startups where people have to take super long holidays after a successful exit because they've worked insane hours. However it was mostly self inflicted.
So yes, please adopt our work ethic and legal framework. It's going to help us tremendously.
