Whether a nonexempt employee is paid on an hourly, piece work, salary, or any other basis, such payments shall not serve to compensate the employee for any portion of the overtime rate for hours worked over 40 in a work week, except that this limitation only applies to the "one-half" portion of the overtime rate (one and "one-half" times an employee's regular hourly rate) when overtime is determined on a bona fide fluctuating workweek basis.
The overtime rate for a tipped employee receiving the service rate shall be computed at one and one half times the basic minimum wage, except where exempted by M.G.L. c. 151, § 1A.
