Unfortunately, culture follows economic conditions, not the other way around. So without a legal limit, I believe not only that culture would permit it, but also it would find a way to justify it.
(See e.g. US work ethics/protestant work culture.)
There is a workaround against that: Have a legal requirement that overtime should average to zero or less (to allow for part-time employees) over the course of a year across all employees of the workplace.
Lots of jobs require mandatory overtime, whether salaried office jobs which expect folks to finish unreasonable workloads or hourly physical jobs which have artificially limited the number of workers (by regulations or union contracts) but have minimum staffing levels, e.g. police, prisons, assembly line workers, etc.
There isn't one single culture here. Plenty of cultures not just permit it, they expect it.
