A. The board or local board shall, upon receipt of a petition for a representation election filed by a labor organization, designate the appropriate bargaining units for collective bargaining.

The parties, by mutual agreement, may further consolidate occupational groups. Essential factors in determining appropriate bargaining units shall include the principles of efficient administration of government, the history of collective bargaining and the assurance to public employees of the fullest freedom in exercising the rights guaranteed by the Public Employee Bargaining Act.

B. Within thirty days of a disagreement arising between a public employer and a labor organization concerning the composition of an appropriate bargaining unit, the board or local board shall hold a hearing concerning the composition of the bargaining unit before designating an appropriate bargaining unit.

C. The board or local board shall not include in an appropriate bargaining unit supervisors, managers or confidential employees.

D. Jobs included within a bargaining unit pursuant to a local ordinance in effect on January 1, 2020 shall remain in that bargaining unit.
