Section 3304 Of Chapter 9.7. Public Safety Officers From California Government Code >> Division 4. >> Title 1. >> Chapter 9.7.

. (a) No public safety officer shall be subjected to punitive action, or denied promotion, or be threatened with any such treatment, because of the lawful exercise of the rights granted under this chapter, or the exercise of any rights under any existing administrative grievance procedure. Nothing in this section shall preclude a head of an agency from ordering a public safety officer to cooperate with other agencies involved in criminal investigations. If an officer fails to comply with such an order, the agency may officially charge him or her with insubordination.
  (b) No punitive action, nor denial of promotion on grounds other than merit, shall be undertaken by any public agency against any public safety officer who has successfully completed the probationary period that may be required by his or her employing agency without providing the public safety officer with an opportunity for administrative appeal.
  (c) No chief of police may be removed by a public agency, or appointing authority, without providing the chief of police with written notice and the reason or reasons therefor and an opportunity for administrative appeal. For purposes of this subdivision, the removal of a chief of police by a public agency or appointing authority, for the purpose of implementing the goals or policies, or both, of the public agency or appointing authority, for reasons including, but not limited to, incompatibility of management styles or as a result of a change in administration, shall be sufficient to constitute "reason or reasons."
