Four weeks of vacation is the minimum set by law in most European countries. An exception is, for example, Poland, where the length of leave depends on the length of experience. Employees with less than 10 years of experience have four weeks of vacation, others six days more. Similarly, employees in Austria are entitled to 25 days of vacation if their experience is less than 25 years, while others are entitled to five days more. In Slovakia, employees under 33 have four weeks of vacation, and those over 33 have an extra week.
