Notwithstanding the provisions of Section 45113, the governing board may lay off and reemploy classified employees only in accordance with procedures provided by Sections 45298 and 45308, except the term “personnel commission” therein shall be construed to mean the governing board. “Governing board” as used in this section shall include districts governed by a common board or by different boards but with a common administration. Employees in common board or common administration districts shall, for the purpose of layoff for lack of work or funds, be considered as having been employed in a single district.
