Question: “How do I decided when to drug test for an injury?”

Answer: “The rule does not prohibit drug testing of employees. It only prohibits employers from using drug testing, or the threat of drug testing, as a form of retaliation against employees who report injuries or illnesses. If an employer conducts drug testing to comply with the requirements of a state or federal law or regulation, the employer's motive would not be retaliatory and this rule would not prohibit such testing.”
