California
Education Code § 45127
(b) Notwithstanding this section and Section 45128 , a governing board may, with the approval of the personnel commission, where applicable, exempt specific classes of positions from compensation for overtime in excess of eight hours in one day, provided that hours worked in excess of 40 in a calendar week shall be compensated on an overtime basis. This exemption applies only to those classes that the governing board and personnel commission, where applicable, specifically find to be subject to fluctuations in daily working hours not susceptible to administrative control, such as security patrol and recreation classes, but shall not include food service and transportation classes.
(c) This section applies to districts that have adopted the merit system in the same manner and effect as if it were a part of Article 6 (commencing with Section 45240 ).
