Cal. Government Code § 19887.2

(a) For all purposes of this part such persons are employees of the department and not of the appointing power to which they are assigned. The department shall make all necessary rules to carry out the purposes of this article. The procedure authorized by this article for procuring temporary clerical help is an alternative to other procedures for that purpose authorized by this part or department rule and nothing in this article, nor in the rules made hereunder, prevents an appointing power from following such other procedures. (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.
