Just to add some information for Poland.

The standard is 20 days of holidays, although if you've been in the workforce for long enough (I think it's 10 years) or completed tertiary studies and worked for a few less years you'll get 26 days of holidays each year.

There is paid overtime with a maximum number of days and hours that you can work per year. Though in my industry some people end up chewing through that within the first few months. Things are better in this company for now.

As far as job hopping on the resume, I think the optimal thing to do is to hop every few years, but I don't see that as a negative.
