Gov. Code, § 19996.2

(a) Absence without leave, whether voluntary or involuntary, for five consecutive working days is an automatic resignation from state service, as of the last date on which the employee worked.

A permanent or probationary employee may within 90 days of the effective date of such separation, file a written request with the department for reinstatement; provided, that if the appointing power has notified the employee of his or her automatic resignation, any request for reinstatement must be made in writing and filed within 15 days of the service of notice of separation. Service of notice shall be made as provided in Section 18575 and is complete on mailing. Reinstatement may be granted only if the employee makes a satisfactory explanation to the department as to the cause of his or her absence and his or her failure to obtain leave therefor, and the department finds that he or she is ready, able, and willing to resume the discharge of the duties of his or her position or, if not, that he or she has obtained the consent of his or her appointing power to a leave of absence to commence upon reinstatement.

An employee so reinstated shall not be paid salary for the period of his or her absence or separation or for any portion thereof.

(b) If the provisions of this section are in conflict with the provisions of a memorandum of understanding reached pursuant to Section 3517.5, 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.
