We have to differentiate between two situations. If the employer sets a date for your annual leave, the worker must abide by this date and he / she must obtain the leave during this date.

Article 80
The employer shall fix the date- of the annual leave for the worker in accordance with the work requirements and may divide the leave with the consent of the worker provided that the division shall not be into more than two periods.
The employer may on a written application of the worker postpone not more than half of the annual leave to the year following the year of its entitlement.
