Direct threat refers to a specific and immediate risk or danger posed by an employee's behavior or condition that can result in harm to themselves, their colleagues, or the workplace environment.

Example
If an employee in a manufacturing plant consistently operates heavy machinery while visibly impaired by drugs or alcohol, it creates a direct threat to workplace safety as it increases the likelihood of accidents and injuries. In such cases, HR may need to intervene to mitigate this threat, which could involve disciplinary actions or providing assistance for rehabilitation.
