I. Purpose

The Civil Service Rule 10.3 (A) (10), covering Disciplinary Action, and Personnel Policies of Sonoma County Water Agency, Sonoma County Fair & Exposition, Inc., and Community Development Commission, Agricultural Preservation and Open Space District prohibit the use or possession of drugs or alcohol while on the job or reporting to work while under the influence of drugs or alcohol.


Occasionally an employee may display behaviors on the job that may lead you to believe that the employee is under the influence of drugs or alcohol. When this happens, the Civil Service Rules/County Policies and your job description as a supervisor or manager give you the authority to take action.


Extra Help and contract employees are covered by this policy as well.

II. Policy

The County is a drug-free workplace and prohibits the use of drugs (legal or illegal) and alcohol that impair the employee’s ability to do their job while on duty or subject to being called to duty. Further, the County prohibits the possession of drugs and alcohol while on duty, while on County or Agency property, or when subject to being called to duty. (With the exception of possession in the course and scope of employee’s duties.)


This policy outlines the process a County supervisor should follow if an employee is under reasonable suspicion of impairment due to drug or alcohol use.


Some departments may adopt a policy that has higher standards regarding intoxicants and/or drugs, based on lawful and appropriate job-related justification or policies that allow the possession and/or limited use of intoxicants for lawful and appropriate job-related purposes (e.g. Sheriff’s undercover operations, etc.) and after consultation with Human Resources and employee organizations. Definition, procedures, and justification are found in specific department policies. The policy that holds a higher standard regarding intoxicants and/or drugs will supersede when department and county wide policy conflict.

If the employee admits to being under the influence, consult with your supervisor or your Department Human Resources Contact, and do what you can to protect the health and safety of the employee and the rest of your staff.
