Gov. Code, § 3500

(a) It is the purpose of this chapter to promote full communication between public employers and their employees by providing a reasonable method of resolving disputes regarding wages, hours, and other terms and conditions of employment between public employers and public employee organizations. It is also the purpose of this chapter to promote the improvement of personnel management and employer-employee relations within the various public agencies in the State of California by providing a uniform basis for recognizing the right of public employees to join organizations of their own choice and be represented by those organizations in their employment relationships with public agencies. Nothing contained herein shall be deemed to supersede the provisions of existing state law and the charters, ordinances, and rules of local public agencies that establish and regulate a merit or civil service system or which provide for other methods of administering employer-employee relations nor is it intended that this chapter be binding upon those public agencies that provide procedures for the administration of employer-employee relations in accordance with the provisions of this chapter. This chapter is intended, instead, to strengthen merit, civil service and other methods of administering employer-employee relations through the establishment of uniform and orderly methods of communication between employees and the public agencies by which they are employed.

(b) The Legislature finds and declares that the duties and responsibilities of local agency employer representatives under this chapter are substantially similar to the duties and responsibilities required under existing collective bargaining enforcement procedures and therefore the costs incurred by the local agency employer representatives in performing those duties and responsibilities under this chapter are not reimbursable as state-mandated costs.
