This Note also identifies certain credits applicable to the employer's FLSA overtime pay obligations as well as other regular rate issues, such as the treatment of commissions, tips, and piece rates. This Note is based on federal law and applies to private sector employment. State and local law may impose different or additional requirements on overtime pay.
