How much annual leave an employee earns
Article 109 provides that an employee is entitled to paid annual leave of no less than twenty-one days, rising to no less than thirty days once the employee has completed five continuous years in the employer's service.
This is a floor, not a ceiling. An establishment may grant more in the contract or in its work regulations, and what it grants becomes binding on it.
The days are calendar days rather than working days, so weekly rest days and holidays falling inside the leave period count towards it unless otherwise agreed.
