Private employers may test applicants and employees. Employers that follow the Drug-Free Workplace Program receive additional legal protections.
Employers that participate in Tennessee’s Drug-Free Workplace Program must maintain a written drug testing policy.
The policy should explain:

- Disciplinary actions
- Employee rights
Policies must be shared with employees and applicants before testing.
Pre-employment testing is allowed after a conditional job offer.
Applicants who fail testing may be denied employment. Testing must be applied consistently across similar roles.
Safety-sensitive positions often require stricter screening.
Employers may test employees under several conditions.
These include reasonable suspicion, post-accident incidents, random testing, and return-to-duty programs. Testing must align with company policy.
Reasonable suspicion testing occurs when observable behavior suggests impairment.
Signs include slurred speech, impaired coordination, confusion, or unsafe behavior.
Supervisors should document observations promptly. Documentation protects employers and employees.
