What might be a sign of fatigue affecting job performance?

Fatigue can significantly impact job performance, and one of the most common signs of this is experiencing slower reaction times. When an individual is fatigued, their cognitive and physical capabilities can diminish, leading to delays in responses to tasks or situations that require quick thinking or action. This decline in reaction time can affect safety and productivity, especially in environments where rapid responses are critical.

In contrast, increased efficiency, heightened focus, or better memory recall are typically associated with optimal functioning, not fatigue. A person who is fatigued is unlikely to experience these positive outcomes, making slower reaction times a more accurate indicator of diminished performance due to fatigue. Recognizing this sign is crucial for assessments related to fitness for duty and ensuring that individuals are operating under safe and effective conditions.
