Safety sensitive individuals and employees are required to submit to any test (drug, alcohol or both) that a supervisor requests, based on reasonable suspicion. Reasonable suspicion is described as one or more trained supervisors reasonably believing or suspecting that you are under the influence of drugs or alcohol. Supervisors can NOT require testing based on a hunch or guess alone; their suspicion must be based on observations concerning appearance, behavior, speech and smell that are usually associated with drug or alcohol use
