What should never be done during an intervention for a colleague diverting narcotics?

Leaving the individual alone once the intervention has started is critical to avoid potential escalation of the situation. When addressing issues such as narcotics diversion, it is essential to maintain a supportive environment and ensure the safety of everyone involved, including the individual being confronted. Leaving them alone can lead to various adverse outcomes, such as their potential for harming themselves or others, the possibility of them attempting to dispose of evidence, or even fleeing the situation altogether.

In these delicate situations, having a consistent and supportive presence can help de-escalate tensions and encourage open communication. Therefore, remaining with the individual helps to ensure that the intervention can proceed in a structured and safe manner.
