Final answer:
A supervisor does not need to have absolute certainty for a Reasonable Cause Determination before sending an employee to a drug or alcohol test; they only need a reasonable suspicion based on specific observations.
Step-by-step explanation:
The statement that a supervisor must have ABSOLUTE CERTAINTY as the result from a Reasonable Cause Determination before sending an employee to a drug or alcohol test is False.
Reasonable cause testing is based on the standard that the supervisor has a reasonable suspicion, not absolute certainty. This suspicion is generally based on specific, contemporaneous, articulable observations concerning the appearance, behavior, speech, or body odors of the employee. The observations may include signs of drug use or alcohol misuse. These observations can be made by supervisors or by other company officials who are trained to detect the signs and symptoms of drug and alcohol use.
