Gov. Code, § 3504.5

(a) Except in cases of emergency as provided in this section, the governing body of a public agency, and boards and commissions designated by law or by the governing body of a public agency, shall give reasonable written notice to each recognized employee organization affected of any ordinance, rule, resolution, or regulation directly relating to matters within the scope of representation proposed to be adopted by the governing body or the designated boards and commissions and shall give the recognized employee organization the opportunity to meet with the governing body or the boards and commissions.

(b) In cases of emergency when the governing body or the designated boards and commissions determine that an ordinance, rule, resolution, or regulation must be adopted immediately without prior notice or meeting with a recognized employee organization, the governing body or the boards and commissions shall provide notice and opportunity to meet at the earliest practicable time following the adoption of the ordinance, rule, resolution, or regulation.

(c) The governing body of a public agency with a population in excess of 4,000,000, or the boards and commissions designated by the governing body of such a public agency shall not discriminate against employees by removing or disqualifying them from a health benefit plan, or otherwise restricting their ability to participate in a health benefit plan, on the basis that the employees have selected or supported a recognized employee organization. Nothing in this section shall be construed to prohibit the governing body of a public agency or the board or commission of a public agency and a recognized employee organization from agreeing to health benefit plan enrollment criteria or eligibility limitations.
