The Department of Labor reminds you that the Mid-Autumn Festival is a national holiday. If the employees attend on that day, the employers will be required to pay twice the usual amount for the attendance.
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. This shall also apply when, with the consent of the worker or the labor union, the worker is required to work to meet seasonal needs.
