Accumulated holidays and leaving a job
If you leave your job (e.g. found a new job in the Netherlands) and you have accumulated holiday leave, it is wise to take that time off before the end of your contract - after discussing this arrangement with your employer.
It’s also possible to have your accumulated days paid out when you leave a job. However, employers are only required to pay out leave above the legal minimum 20-day amount, so you may not receive complete compensation for the total number of days owing.
