This bill, known as the Holiday Pay Act, amends the Fair Labor Standards Act of 1938 (FLSA) to establish a new requirement for compensating employees who work on legal public holidays. It mandates that employers must pay employees at a rate of not less than one and one-half times their regular rate for any work performed on a legal public holiday, as defined by existing federal law. The legislation integrates this new holiday pay requirement into the FLSA's enforcement mechanisms, ensuring that violations can be addressed similarly to unpaid minimum wages or overtime compensation. It also clarifies that this premium holiday pay is distinct and not creditable towards an employee's regular overtime compensation calculations. Furthermore, the bill includes several conforming amendments to various sections of the FLSA and the Portal-to-Portal Act of 1947. These changes ensure consistency across the law regarding exemptions, prohibited acts, and the statute of limitations for claims related to unpaid legal public holiday compensation. The Act also specifies that it does not supersede any federal, state, or local laws that provide for higher holiday pay rates or compensation for additional holidays.
