Generally, non-managerial employees working more than forty hours in any given week must be paid one and one half times their regular rate of pay. There are several exemptions to this requirement. The exemptions can be found in M.G.L. c. 151, s. 1A. The exemptions under federal law are different ( Department of Labor).
Overtime Pay Rates
Employees are to be paid time and one half their regular hourly rate for all hours worked over 40 in one week. If a pay period is bi-weekly and the employee works 60 hours during the first week and 20 in the second, the employee must be paid time and one half for the overtime hours (20) worked during the first week.
