Labor Relations

The Labor Relations Services Unit develops and implements the County's labor relations goals, policies and priorities and manages the negotiations process with the employee associations/unions. Formerly a Unit of the Human Resources Department, the Labor Relations Service Unit was moved to the County Administrator's Office on July 1, 2014. Contact Number: 925-655-2068

County employees are represented in 34 bargaining units by 16 labor organizations.  All employee organizations are currently under contract and MOUs with the employee organizations are current and remain in full force and effect.  We are currently negotiating a Remote Work Policy with all labor partners as a coalition and are in planning for California Nurses Association Negotiations.
