Step-by-step explanation:
In the workplace, a trained supervisor should intervene immediately after witnessing obvious impairment or distribution of drugs. This is important for ensuring the safety of employees and maintaining a drug-free environment. When a supervisor observes impairment or drug distribution, they should approach the situation calmly and discreetly. They should gather any necessary evidence and document the incident. Once they have enough information, they should report the incident to their higher-ups or the appropriate authorities, following the protocol established by their organization.By intervening promptly, the supervisor can mitigate risks, protect affected individuals, and uphold the standards of the workplace.
