Holiday pay is an allowance that an employee earns through work in the calendar year prior to the year of the holiday. It is usually a percentage supplement to the salary that has been paid the year before the holiday pay is to be paid. In some jurisdictions, it may take the form of fully or partially paid time off, or a bonus or additional hourly pay for work performed on a holiday. In the United States, paid holidays off are not required by law, nor are there any requirements that an employer offer additional compensation for work performed during holidays. The Fair Labor Standards Act (FLSA) does not require payment for time not worked, such as vacations or holidays (federal or otherwise)
