Cal. Education Code § 89553

(a) After a determination has been made of the class or teaching service area to be reduced and the number of employees in such class or area to be laid off, the president or chancellor shall notify each employee to be laid off, that the employee is being laid off for lack of funds or lack of work. Such notice shall be in writing and mailed by certified mail, return receipt requested, to the employee’s last known address, or the notice may be delivered to the employee in person who shall acknowledge receipt of the notice in writing. The notice shall specify the effective date of layoff and shall be delivered to the employee or mailed to the employee’s last known resident address at least 30 days, whenever possible, prior to the effective date of the layoff. When curricular shifts or other program changes, which can be anticipated, are to be made those who will be laid off will normally be notified at least one year in advance. (b) If the provisions of this section are in conflict with the provisions of a memorandum of understanding reached pursuant to Chapter 12 (commencing with Section 3560) of Division 4 of Title 1 of the Government Code, the memorandum of understanding shall be controlling without further legislative action, except that if such provisions of a memorandum of understanding require the expenditure of funds, the provisions shall not become effective unless approved by the Legislature in the annual Budget Act.
