What drives fatigue in shifts
- Night frequency and sequences: limit consecutive nights; manage total nights per 28 days.
- Quick returns: avoid rest periods under 11 hours between duties.
- Long runs: cap consecutive workdays and provide protected recovery breaks.
- Extended shifts: higher risk beyond 10–12 hours, especially on nights.
- Overtime and commute: factor real travel time and typical overtime.
- Task load: heavy cognitive/physical demand increases risk.
- Safety-critical windows: 02:00–06:00 needs extra controls.
Evidence-based roster design
- Rotate forward where possible; avoid permanent nights unless voluntary with controls.
- Protect minimum rest of 11h (target 12h) and schedule longer recovery after nights.
- Set caps: e.g., max 3–4 nights in a row; limit >10h shifts; plan reset days.
- Fairness rules: even weekend/holiday distribution; transparent patterns.
- Buffers: planned absence cover and surge capacity to prevent unsafe overtime.
- Commute-aware: adjust start/finish to public transport and peak traffic.
- Break design: predictable breaks; strategic naps on nights where policy allows.
- Allowances: align payments with fatigue exposure, not just hours.
Practical, role-specific learning
- Manager modules: risk factors, roster levers, monitoring and incident response.
- Supervisor toolkits: allocating duties, protecting breaks, managing overtime.
- Staff sessions: sleep strategies, commute planning, nutrition and hydration.
- Formats: onsite workshops, live online, video courses and handbooks.
