What behavioral changes might indicate a chemically impaired employee?

• A. Normal mood with steady performance
• B. Excellent punctuality
• C. Consistent work quality
• D. Increased irritability

Answer: (D)

Behavioral shifts can signal a problem with substances, so noting changes in how a person acts is essential for safety and support. Increased irritability stands out as a warning sign because substances often disrupt emotional regulation and impulse control. When someone who normally maintains calm becomes unusually huffy, easily angered, or hostile, it may reflect impairment from alcohol or drugs, withdrawal, or the effects of fatigue and stress linked to substance use. This kind of mood change can precede or accompany declines in attention, judgment, and job safety, making it the most likely indicator among the options.

In contrast, a normal mood with steady performance, excellent punctuality, or consistently good work quality suggests the employee is functioning reliably at the moment, with no obvious behavioral signal of impairment. The key is to recognize a shift from that person’s baseline and to follow proper protocols for reporting concerns and offering support, such as consulting a supervisor and engaging employee assistance resources to address safety and well-being.
