Section 1A. Except as otherwise provided in this section, no employer in the commonwealth shall employ any of his employees in an occupation, as defined in section two, for a work week longer than forty hours, unless such employee receives compensation for his employment in excess of forty hours at a rate not less than one and one half times the regular rate at which he is employed. Sums paid as commissions, drawing accounts, bonuses, or other incentive pay based on sales or production, shall be excluded in computing the regular rate and the overtime rate of compensation under the provisions of this section. In any work week in which an employee of a retail business is employed on a Sunday or certain holidays at a rate of one and one-half times the regular rate of compensation at which he is employed as provided in chapter 136, the hours so worked on Sunday or certain holidays shall be excluded from the calculation of overtime pay as required by this section, unless a collectively bargained labor agreement provides otherwise. Except as otherwise provided in the second sentence, nothing in this section shall be construed to otherwise limit an employee's right to receive one and one-half times the regular rate of compensation for an employee on Sundays or certain holidays or to limit the voluntary nature of work on Sundays or certain holidays, as provided for in said chapter 136.
