Which of the following is NOT listed as a sign that a colleague may be impaired?

• A. Unexplained Lateness
• B. Sudden Isolation
• C. Not Responding To Pages Or Calls
• D. Failing To Maintain Professional Appearance

Answer: (D)

The main idea here is that impairment is typically reflected in how someone functions at work—how reliably they show up, how they communicate, and how they respond to others—rather than on appearance alone. Not responding to pages or calls is a clear red flag because it directly affects safety and workflow; it shows a drop in responsiveness and engagement. Sudden isolation signals a change in behavior or social interaction, which can accompany impairment in some cases. Unexplained lateness points to changes in alertness or reliability that could be tied to impairment. Failing to maintain a professional appearance, while it can raise concerns about professionalism or personal circumstances, is not a reliable indicator of impairment by itself and can have many non-impairment explanations. So the option about appearance is not listed as a sign of impairment in the typical workplace indicators.
