State exempts virtually the same as federal Non-exempts. 14 separate classes. Specific rules are found on Work Orders by Industry or Occupation. Most of the major working conditions are standard across industry. Compensatory Time - Comp Time Time off for overtime worked.
Federal law permits comp time in the week the overtime was worked.
Exempt workers work until the work is done without overtime. Accounting for comp time undermines the philosophy of the exemption and threatens the exemption. In my judgment it is assumed that exempt workers have discretion over their work. That includes discretion about when to come and go. There should be no problem if the employee arranges her work schedule.
