County Employees Retirement Law of 1937: employees.

Senator Grayson's retirement system membership legislation codifies existing practices under the County Employees Retirement Law of 1937 (CERL) by explicitly prohibiting counties and districts from excluding any employees from retirement system participation, except for temporary, seasonal, intermittent, and part-time workers.

The measure clarifies that counties and districts operating retirement systems under CERL must enroll all eligible employees, with exclusions permitted only for specific categories as determined by retirement boards. These categories encompass temporary, seasonal, intermittent, and part-time positions already defined in existing state law. The bill's findings state that these provisions apply uniformly across California, including charter cities and counties, as a matter of statewide concern rather than municipal affairs.

By adding Section 31566 to the Government Code, the legislation formalizes current interpretations of CERL membership requirements while maintaining retirement boards' authority to determine employee eligibility based on employment status. The measure contains no new appropriations or enforcement mechanisms beyond existing administrative frameworks.
