California Code, Government Code - GOV § 19997.5

(a) Separations that are necessary by reason of reinstatement of an employee or employees after recognized military service as provided for in Section 19780 shall be made by layoff. In making these separations, the regular method of determining the order of layoff shall be used unless this would result in the layoff of an employee who has been reinstated in the class and subdivision of layoff under Section 19780, and in the retention of an employee who was appointed in the class and subdivision of layoff during the time that a reinstated employee was on military leave. Under these circumstances, seniority shall not be counted as provided in Section 19997.3. Instead, service in the subdivision of layoff that qualifies under Section 19997.3 for credit is the only state service that shall be counted.

Whenever such a layoff results in the demotion to a lower class of an employee who has been reinstated after recognized military service as provided in Section 19780, the resulting layoff, if any, in the lower class shall be made as though that reinstated employee had been in that lower class at the time he or she went on military leave.

Any layoff occurring within one year after reinstatement of an employee after recognized military service shall be presumed to have been necessary by reason of reinstatement of an employee or employees under Section 19780 unless the department determines that the reason for layoff is clearly not related to the reinstatement.

(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 the provisions of a memorandum of understanding require the expenditure of funds, the provisions may not become effective unless approved by the Legislature in the annual Budget Act.
