Based on full-time employment you accrue 25 vacation days each year. You can take these days off (in consultation with Charlie works and the company where you work) and have them paid out.
You also build up 8% holiday allowance.
In case you make use of the ET arrangement (in case of double accommodation costs), the extra-statutory vacation days (5) and the holiday allowance will be paid immediately with every salary payment.
Holiday allowance that has not been paid will be paid in the first week of June and at the end of employment at Charlie works.
For further explanation about making the reservations payable, see the CAO for temporary agency workers (articles 60 and 61, click here to read this in Dutch).
