Article 14
The employee shall be entitled, for each Gregorian year served, a three-week annual paid leave, which he may divide and choose when and where to spend it, unless otherwise agreed to in the interest of the user.
The user shall also be entitled, whenever he has spent two years in the service, an air ticket to his country of origin or place of return and return to spend all the leave owed to him or the rest of it, unless the travel is final, he is entitled to a return ticket only to his home country or place of residence.
