All members perform a urine drug screen upon joining the union.

Drug screenings must be updated annually, and members are subject to random drug screenings. For random screenings, you will be notified by your employer.

Your employer should also notify you for annual testing.

Should you not receive a notification from your employer, please contact our office to schedule an appointment. A member may not test without an authorization/e-screen form from the union or contractor.
