Ed. Code, § 45130

Notwithstanding the provisions of Sections 45127 and 45128, a personnel commission, when applicable, or a governing board of a school district may specify certain positions or classes of positions as supervisory, administrative, or executive and exclude the employees serving in such positions and the positions from the overtime provisions.

To be excluded from such overtime provisions, the positions or classes of positions must clearly and reasonably be management positions. In approving positions or classes of positions for exclusion from the overtime provisions, the personnel commission, when applicable, or the governing board of a school district shall certify, in writing, that the duties, flexibility of hours, salary, benefit structure, and authority of the positions or classes of positions are of such a nature that they should be set apart from those positions which are subject to the overtime provisions, and that employees serving in such excluded positions or classes of positions will not be unreasonably discriminated against as a result of the exclusion.

Notwithstanding the provisions of this section, if a person serving in an excluded position is required to work on a holiday, as provided for in this code, or by action of a governing board, he shall be paid, in addition to his regular pay for the holiday, compensation, or given compensating time off, at a rate not less than his normal rate of pay.

This section shall apply 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) of this chapter.
