Cal. Gov. Code § 3555
The Legislature finds and declares that the ability of an exclusive representative to communicate with the public employees it represents is necessary to ensure the effectiveness of state labor relations statutes, and the exclusive representative cannot properly discharge its legal obligations unless it is able to meaningfully communicate through cost-effective and efficient means with the public employees on whose behalf it acts. In most cases, that communication includes an opportunity to discuss the rights and obligations created by the contract and the role of the representative, and to answer questions. That communication is necessary for harmonious public employment relations and is a matter of statewide concern. Therefore, it is the Legislature's intent that recognized exclusive representatives of California's public employees be provided meaningful access to their represented members as described in this chapter unless expressly prohibited by law.
