How does shift work and fatigue affect security performance, and what mitigations help?

• A. Longer shifts with no breaks.
• B. More cameras only.
• C. Ergonomic scheduling, breaks, rotation, hydration, and wellness.
• D. Increase working hours to cover more time.

Answer: (C)

Shift work and fatigue undermine security performance by reducing vigilance, slowing reaction times, impairing decision-making, and eroding situational awareness. In security tasks, where spotting anomalies, sensing threats, and responding quickly are crucial, tired staff are more likely to miss cues, misjudge risk, or take longer to act, creating gaps in protection. The best approach combines strategies that support the human element: ergonomic scheduling that respects natural alertness patterns, regular breaks to restore attention, rotating shifts to distribute circadian disruption, and programs for hydration and overall wellness to sustain mental energy and mood. Together, these mitigations address both the physical and cognitive demands of security work, making it harder for fatigue to degrade performance. Longer shifts with no breaks, more cameras alone, or simply increasing hours to cover more time do not tackle the core human factors and can actually worsen fatigue and errors.
