It’s not hard to work more than 35 hours in France, correct?

I work with teams across Europe and they seems to put in hours that aren’t that different from the US.

I assume that voluntary?

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.
