How to take part-time leave?
Your entitlement to annual leave is not affected by whether you work full-time or part-time. Whether you work full-time or part-time, and regardless of how your part-time work is distributed over the week, your annual leave must be of the same length. The starting point is that a full working week off is equivalent to five days' holiday. You do not get more vacation when you work part-time.
Vacation days can only be taken as full days. This means that even if you work half-time five days a week, you have to take five days of vacation to get a full week off. If you had worked concentrated part-time, your vacation days are converted into net vacation days, usually by taking the number of working days per week times the number of vacation days divided by 5. If you have 25 days of holiday entitlement and work 3 days per week, the number of net holiday days will be (3 x 25)/5= 15 holiday days.
In summary, the length of your vacation is the same regardless of your seniority. What is affected, however, is how much you are paid when you are off, based on your seniority. The starting point is that holiday pay follows the current employment situation. This means that the pay you receive during vacation leave that is scheduled for the period when you are working part-time will be calculated on the part-time salary and not the full-time salary.
