What should a fatigue management program include?

• A. Eliminating breaks to improve throughput.
• B. Schedule design, regular breaks, opportunities for naps, and balanced workload.
• C. Increasing shift length to reduce handovers.
• D. Encouraging workers to rely on caffeine only.

Answer: (B)

Fatigue management works best when rest and work are designed together. A solid program includes how shifts are scheduled to match human alertness, regular breaks to prevent sleep debt, opportunities for naps when appropriate, and a workload that stays within what people can safely handle. These elements support sustained vigilance, faster reaction times, and better decision-making, which in turn reduces errors and safety incidents.

Eliminating breaks removes essential recovery time, leading to higher fatigue and poorer performance. Extending shift length tends to increase fatigue and can drive more mistakes, while often adding more handovers and complexity. Relying on caffeine alone masks sleepiness and doesn’t address underlying fatigue or circadian misalignment, and it can disrupt sleep later. So, the comprehensive approach that combines schedule design with regular breaks, naps, and balanced workload is the most effective.
