How should a supervisor manage fatigue risk across shifts in a high-demand period?

• A. Monitor alertness, implement shift rotation and explicit breaks, ensure adequate rest, hydrate, and adjust workloads as needed.
• B. Require all employees to work continuously without breaks.
• C. Delay any rest periods to meet demand.
• D. Reduce hydration and ignore fatigue indicators.

Answer: (A)

Proactive fatigue risk management across shifts during busy periods focuses on maintaining alertness and safe performance through evidence-based practices. Monitoring alertness helps catch early signs of fatigue before errors occur. Implementing shift rotation distributes workload over different times, supporting better alignment with natural sleep-wake cycles. Explicit breaks provide regular opportunities to rest and recover, reducing the likelihood of microsleeps and performance declines. Ensuring adequate rest between shifts supports recovery, so workers come back with sufficient stamina for the next cycle. Hydration supports cognitive function and physical performance, and staying hydrated helps sustain attention and decision-making. If workloads are adjusted as needed, you prevent overload that can push fatigue to unsafe levels.

Choices that push continuous work without breaks or delay rest undermine safety by allowing fatigue to accumulate. Pushing rest aside to meet demand sacrifices recovery time, increasing error risk. Reducing hydration and ignoring fatigue indicators further degrades cognitive function and safety.
