CA Gov't Code Section 3546.3

Notwithstanding subdivision (i) of Section 3540.1, Section 3546, or any other provision of this chapter, any employee who is a member of a religious body whose traditional tenets or teachings include objections to joining or financially supporting employee organizations shall not be required to join, maintain membership in, or financially support any employee organization as a condition of employment; except that such employee may be required, in lieu of a service fee, to pay sums equal to such service fee either to a nonreligious, nonlabor organization, charitable fund exempt from taxation under Section 501(c)(3) of Title 26 of the Internal Revenue Code, chosen by such employee from a list of at least three such funds, designated in the organizational security arrangement, or if the arrangement fails to designate such funds, then to any such fund chosen by the employee. Either the employee organization or the public school employer may require that proof of such payments be made on an annual basis to the public school employer as a condition of continued exemption from the requirement of financial support to the recognized employee organization. If such employee who holds conscientious objections pursuant to this section requests the employee organization to use the grievance procedure or arbitration procedure on the employee’s behalf, the employee organization is authorized to charge the employee for the reasonable cost of using such procedure.
