Night-shift fatigue and wellbeing in an estates team
A 400-bed hospital's estates team moved to a 12-hour night shift (19:00-07:00) to cover boiler maintenance. Of 22 technicians, nine now work four nights on, four off; overtime is common because of staff shortages. Sickness absence has risen from 3.1% to 5.8% in six months, and two near-miss vehicle incidents occurred at the site gate at 07:10. A supervisor reports 'low mood and snappy behaviour', and one technician has asked for help with sleep problems but does not want to 'make a fuss'. The team has no night-worker health assessment, no rest facilities beyond a chair in the plant room, and no fatigue training. The HR manager proposes a resilience webinar.
1. Assess the main health and wellbeing risks in this team and explain why a resilience webinar alone is inadequate.

The risks are structural as well as individual
Fatigue and circadian disruption. Four 12-hour nights in a row, with overtime, produces cumulative sleep loss and impaired alertness. The 07:10 vehicle near misses are a direct warning: end-of-shift driving after 12 hours is a high-risk period.
Safety-critical errors. Boiler maintenance is safety-critical. Fatigue affects vigilance, reaction time and complex decision-making, so the risk is not only to the technicians but to the plant and patients.
Mental health and presenteeism. 'Low mood and snappy behaviour' can be an early sign of stress, sleep disruption or depression. The technician asking for help with sleep problems is a signal that should be acted on, not left to informal coping.
Musculoskeletal and general health. Long shifts, limited rest facilities and overtime increase strain and reduce recovery time.
Why the webinar is inadequate. A resilience webinar places the burden on individuals to cope with a work design that is causing the problem. It does not address shift length, consecutive nights, overtime, rest facilities, health assessment or supervision. It may be a useful supplement, but on its own it is a cosmetic response to a structural risk. The organisation should apply the hierarchy of controls to work design before asking people to be more resilient.
2. Design a prioritised health and wellbeing programme for the team, covering shift design, health assessment, rest, supervision and monitoring.

Prioritise work design first, then support
1. Shift design and overtime
- Review the 12-hour, four-night pattern. Consider shorter nights, fewer consecutive nights, or a forward-rotating pattern that is easier to tolerate.
- Control overtime: set a maximum and monitor it, because overtime converts a tolerable roster into a fatiguing one.
- Consult the team and representatives before changing the roster; their experience of travel, caring responsibilities and sleep is essential.
2. Night-worker health assessment
- Introduce a confidential health assessment before night work and at regular intervals, with referral to occupational health where needed.
- Use it to identify reasonable adjustments, not to weed out workers. The technician with sleep problems should be offered a confidential OH referral with consent.
3. Rest and facilities
- Provide a proper rest room with low lighting, a place to lie down, and access to food and drink.
- Plan breaks so they are actually taken; a chair in the plant room is not a rest facility.
4. Supervision and fatigue training
- Train supervisors to recognise fatigue and to adjust tasks rather than simply press on.
- Provide practical fatigue training for the team, including driving home after nights and the signs of dangerous sleepiness.
5. Monitoring
- Track absence, overtime, near misses, vehicle incidents and turnover.
- Use a short fatigue or wellbeing survey, and review it with the team.
- Review the programme after three months and adjust.
This sequence addresses the cause before the symptom and gives the webinar, if retained, a supporting role.
3. Advise how to handle the technician's request for help and the supervisor's observations, respecting confidentiality and avoiding stigma.

Handle the individual and the pattern separately
The technician's request
- Respond privately and promptly. Thank the technician for raising it and explain the options without pressure.
- Offer a confidential referral to occupational health with consent. Do not ask for details of sleep problems in the workshop or in front of the team.
- Discuss temporary adjustments: shift pattern, overtime exemption, task rotation, or time off for appointments. Keep the reason confidential.
- Record only what is necessary and store it separately from the general personnel file. Explain who will see it and why.
- Do not treat the request as a weakness or as a disciplinary matter. The aim is to keep the person safe and in work.
The supervisor's observations
- Treat 'low mood and snappy behaviour' as a possible early warning, not a diagnosis. The supervisor should not attempt to counsel the team.
- Encourage the supervisor to check in privately with individuals, listen, and signpost support such as occupational health or an employee assistance programme.
- Ask the supervisor to report patterns, such as increased errors or lateness, through the proper route, while avoiding gossip.
- Provide the supervisor with training on mental health awareness and on the boundaries of their role.
Avoid stigma
Normalise fatigue and wellbeing discussions in team briefings, link them to the roster review, and make clear that adjustments are available to everyone. If only the person who 'makes a fuss' gets help, the culture will punish silence.
