In the absence of a collective bargaining agreement or other written employer-employee agreement providing otherwise, an employee, as defined in section 663, may be employed or permitted to work for no more than 6 consecutive hours at one time unless the employee is given the opportunity to take at least 30 consecutive minutes of rest time, except in cases of emergency in which there is danger to property, life, public safety or public health. This rest time may be used by the employee as unpaid mealtime, but only if the employee is completely relieved of duty.   [PL 2017, c. 219, §7 (AMD).]
