Cal. Gov't Code § 71632.5

(a) Notwithstanding any other provision of law, rule, or regulation, an agency shop agreement may be negotiated between a trial court and a recognized employee organization that has been recognized as the exclusive or majority bargaining agent pursuant to reasonable rules and regulations, and enactments, in accordance with this article. As used in this article, “agency shop” means an arrangement that requires an employee, as a condition of continued employment, either to join the recognized employee organization, or to pay the organization a service fee in an amount not to exceed the standard initiation fee, periodic dues, and general assessments of that organization for the duration of the agreement or a period of three years from the effective date of the agreement, whichever comes first. However, any employee who is a member of a bona fide religion, body, or sect that has historically held conscientious objections to joining or financially supporting recognized employee organizations shall not be required to join or financially support any recognized employee organization as a condition of employment. That employee may be required, in lieu of periodic dues, initiation fees, or agency shop fees to pay sums equal to those dues, initiation fees, or agency shop fees to a nonreligious, nonlabor charitable organization fund exempt from taxation under Section 501 (c)(3) of the Internal Revenue Code, chosen by the employee from a list of at least three funds, designated in a memorandum of understanding or agreement between the trial court and the recognized employee organization, or if the memorandum of understanding or agreement fails to designate any funds, then to any fund chosen by the employee. Proof of those payments shall be made on a monthly basis to the trial court as a condition of continued exemption from the requirement of financial support to the recognized employee organization.
(b) An agency shop provision in a memorandum of understanding or agreement which is in effect may be rescinded by a majority vote of all the employees in the unit covered by the memorandum of understanding or agreement under the following circumstances:
1. (1) A request for the vote is supported by a petition containing the signatures of at least 30 percent of the employees in the unit.
2. (2) The vote is by secret ballot.
3. (3) The vote may be taken at any time during the term of the memorandum of understanding or agreement, but in no event shall there be more than one vote taken during that term.
(c) In addition to the procedure prescribed in subdivision (a), an agency shop arrangement between the trial court and a recognized employee organization or recognized employee organizations shall be placed in effect, without a negotiated agreement, upon (1) a signed petition of at least 30 percent of the employees in the applicable bargaining unit requesting an agency shop agreement and an election to implement an agency fee arrangement, and (2) the approval of a majority of employees who cast ballots and vote in a secret ballot election in favor of the agency shop agreement. The petition may only be filed after the recognized employee organization has requested the trial court to negotiate on an agency shop arrangement and, beginning seven working days after the trial court received this request, the two parties have had 30 calendar days to attempt good faith negotiations in an effort to reach agreement. An election, that may not be held more frequently than once a year, shall be conducted by the California State Mediation and Conciliation Service in the event that the trial court and the recognized employee organization cannot agree within 10 days from the filing of the petition to select jointly a neutral person or entity to conduct the election. In the event of an agency fee arrangement outside of an agreement that was in effect on January 1, 2002, the recognized employee organization shall defend, indemnify, and hold the trial court harmless against any liability arising from any claims, demands, or other action relating to the trial court’s compliance with the agency fee obligation. Upon notification to the trial court by the recognized employee organization, the amount of the fee shall be deducted by the trial court from the wages or salary of the employee and paid to the employee organization. This subdivision shall be applicable on the operative date of this section, except that if a memorandum of understanding or agreement between the trial court and a recognized employee organization was in effect before January 1, 2002, as to the employees covered by the memorandum of understanding or agreement, the implementation date of this subdivision shall be either the date a successor memorandum of understanding or agreement is effective or, if no agreement for a successor memorandum of understanding or agreement is reached, 90 days from the date of the expiration of the predecessor memorandum of understanding or agreement. The trial court and representatives of recognized employee organizations may mutually agree to a different date on which this subdivision is applicable.
(d) Notwithstanding subdivisions (a), (b), and (c), the trial court and the recognized employee organization may negotiate, and by mutual agreement provide for, an alternative procedure or procedures regarding a vote on any agency shop agreement.
(e) An agency shop agreement or arrangement does not apply to management, confidential, or supervisory employees. If those employees nonetheless choose to join the recognized employee organization and pay dues or pay the organization a service fee, Section 71638 shall apply to those employees, and the trial court shall administer deductions for which the recognized employee organization shall defend, indemnify, and hold the trial court harmless.
(f) Every recognized employee organization that has agreed to an agency shop provision, or is a party to an agency shop arrangement, shall keep an adequate itemized record of its financial transactions and shall make available annually, to the trial court with which the agency shop provision was negotiated, and to the employees who are members of the organization, within 60 days after the end of its fiscal year, a detailed written financial report thereof in the form of a balance sheet and an operating statement, certified as to accuracy by its president and treasurer or corresponding principal officer, or by a certified public accountant. An employee organization required to file financial reports under the federal Labor-Management Disclosure Act of 1959 covering employees governed by this chapter or required to file financial reports under Section 3546.5, may satisfy the financial reporting requirement of this section by providing the trial court with a copy of those financial reports.
(g) This section shall become operative only if Section 3502.5 is amended to provide that a 30-percent or greater showing of interest by means of a petition requires an election regarding an agency shop, and a vote at that election of 50 percent plus one of those voting secures an agency shop arrangement.
(h) A trial court may not offer employees inducements or benefits of any kind in return for employees opposing or rescinding an agency shop arrangement.
