Thus, an employee in this industry who is otherwise exempt under rule 218.1(91D), 218.2(91D) or 218.3(91D) and who is employed at a base rate of at least $500 a week is exempt if the employee is paid at least pro rata (based on a week of not more than six days) for any week when the employee does not work a full workweek for any reason. Moreover, an otherwise exempt employee in this industry qualifies for exemption if the employee is employed at a daily rate under the following circumstances:
