In most European countries you get 2-3 paid leave days each month, so it almost happens here that week could be considered four working days.

More in detail from Finland the law says that everyone must use two weeks from those in one go, once a year. Commonly people take four weeks summer and one week on winter.

Also when you are on vacation, you get 1.5x the salary for that month. It is called "returning from holiday money" (lomaltapaluuraha). It ensures that you want to go back to working after being free for a moment :). That is not in law, but every union has that written in the general working contract. All work places are unionized here.

And don't confuse sick days to paid leave. If you are sick those never use vacation days. If you get sick on vacation, it doesn't use your vacation days, because you are then on sick leave.
