Cal. Government Code § 19855

Any state employee who was laid off from the Department of Employment on the 31st day of December 1941 and thereafter entered the employ of the United States Employment Service and who returned to state service prior to November 16, 1946 and any person who entered the employ of the United States Employment Service after December 31, 1941 and who, prior to November 16, 1946, entered the state service in the Department of Employment may have the department determine the extent, if any, to which such employee shall be entitled to have credited to him in the state civil service, seniority credit, sick leave and accumulated vacation because of service in the United States Employment Service. The department shall limit such determination to the time any such employee was actually employed in the United States Employment Service, including time spent in war service in another federal department if such employee was transferred from the United States Employment Service to another federal department for war service and such employee subsequently entered the employ of the Department of Employment prior to November 16, 1946, and such seniority credits and accumulated sick leave and accumulated vacation shall not exceed that to which each employee would be entitled if he had been continuously employed by the State of California. The foregoing provisions shall likewise apply to former employees of the Department of Employment who although otherwise entitled to such determinations entered recognized military service from federal employment and were reemployed by the Department of Employment within six months after their release from the military service and within six months from the termination of the state military emergency as proclaimed by the Governor. Such time spent in the military service shall be construed as time spent on military leave from the state civil service.
