Labor Standards Act Article 39

Wages shall be paid by an employer to a worker for taking leaves for regular leaves and rest days as stipulated by Article 36, for holidays as stipulated under Article 37, and annual paid leaves as stipulated by Article 38. When an employer has obtained the consent of a worker to work on a holiday, the employer shall pay the worker at double the regular rate for such work.
