Maintaining a safe and drug-free workplace depends on set processes that involve multiple entities including the employer, the supervisor, the company representative, collector and lab personnel, the Medical Review Officer (MRO), the Substance Abuse Professional (SAP) and, often, the Third Party Administrator or Consortium.

Reasonable Suspicion (or Reasonable Cause) testing is one important component of the drug-free workplace policy. Supervisors responsible for making a Reasonable Suspicion determination have a critical role in preventing impaired employees from engaging in safety-sensitive work. Federal testing regulations provide guidance on the:

  • process and protocols of Reasonable Suspicion testing
  • qualifications and professional judgment the supervisor must have to make a Reasonable Suspicion determination
  • Reasonable Suspicion training requirements
