Only France has a 35 hour work week. 35 or 40, not much of a difference but nevertheless important since you can have a decent lunch break and still spend meaningful time with your kids if we account for commuting etc.
One gets get paid overtime for anything more than the 35h work week and can work up a limit of h/yr overtime. They also reduced overtime payments. If the company needs 70h per week from an employee, they'd probably be better off employing two people anyway, at least in theory.
