As winter approaches, workplaces typically experience a rise in seasonal illnesses such as colds, influenza, coughs and throat infections. Colder weather, increased time indoors and reduced ventilation can all make it easier for viruses to spread between people and across shared surfaces.
The consequences can be significant. High levels of sickness absence affect productivity, service delivery, employee wellbeing and operational resilience. For Facilities Managers, winter health therefore becomes an important part of maintaining a safe, effective and supportive workplace.
While seasonal illness cannot be eliminated entirely, proactive facilities management can help reduce transmission, reassure employees and limit disruption.
Winter illnesses can affect organisations in several ways:
Employees who continue working while unwell may also spread illness to colleagues, potentially extending the disruption.
Facilities teams are well placed to reduce these risks because they manage many of the physical conditions that influence workplace health, including cleaning, ventilation, washrooms, shared spaces and building occupancy.
Regular cleaning remains one of the simplest and most effective winter precautions.
Facilities Managers should review whether cleaning schedules are appropriate for the building’s occupancy and risk profile, particularly during periods of increased illness.
Priority areas may include:
Cleaning teams should have access to suitable products, clear instructions and appropriate personal protective equipment where required.
The focus should be on consistent, evidence-led cleaning rather than simply increasing activity everywhere without considering actual use.
Ventilation plays an important role in maintaining a healthy indoor environment.
During winter, windows are often kept closed to retain heat, which can reduce the supply of fresh air. Facilities Managers should therefore ensure ventilation systems are operating correctly and providing adequate airflow.
This may involve:
HEPA filtration may provide additional support in some settings, although it should complement rather than replace effective ventilation and wider hygiene measures.
Air quality should also be balanced against energy efficiency and occupant comfort.
Employees are more likely to follow good hygiene practices when the necessary facilities are visible, accessible and well maintained.
Facilities teams should ensure there are sufficient supplies of:
Hand-sanitising stations may be useful at entrances, reception areas, shared kitchens and other high-traffic locations.
Signage can provide helpful reminders, but it should remain clear and proportionate rather than overwhelming employees with constant instructions.
Shared kitchens, breakout areas, lifts and meeting rooms can become important transmission points during periods of seasonal illness.
Facilities Managers may wish to review:
Where possible, meeting rooms should be aired between use, and heavily occupied spaces should receive additional attention.
Occupancy data can help identify where resources should be concentrated.
Facilities Management cannot address winter illness alone.
Close cooperation with HR and senior leadership is essential, particularly around sickness absence, flexible working and employee communications.
Employees should feel able to stay at home when genuinely unwell rather than feeling pressured to attend and potentially infect others.
Clear policies may cover:
Facilities teams can provide information about the physical workplace, while HR manages the employment and wellbeing aspects.
Employers may choose to share information about seasonal vaccinations or provide access to workplace flu vaccination programmes.
Any communication should be factual, respectful and voluntary.
Facilities Managers may support the practical delivery of vaccination clinics by coordinating:
This should be done in partnership with HR and qualified healthcare providers.
Seasonal illness may also affect cleaning, maintenance, security and front-of-house teams.
Facilities Managers should consider operational resilience by reviewing:
A winter plan should not assume that every team member or supplier will remain fully available throughout the season.
Organisations should be prepared for localised outbreaks or unusually high levels of absence.
A practical response plan may include:
Responsibilities should be clear so that decisions can be made quickly.
CAFM and workplace-management platforms may help teams record actions, share updates and coordinate responses across multiple sites.
Health communications should be calm, practical and proportionate.
Employees need to understand:
Avoid creating unnecessary alarm. The objective is to encourage sensible precautions and demonstrate that the workplace is being managed responsibly.
Some employees may be at greater risk from seasonal respiratory illnesses because of age, pregnancy, disability or underlying health conditions.
Facilities Managers should work with HR and occupational health to consider any appropriate workplace adjustments.
These might include:
Decisions should be handled sensitively and confidentially.
Before winter pressures increase, review whether:
Seasonal illness is an unavoidable part of winter, but its impact can be reduced through thoughtful workplace management.
Facilities Managers have an important role in maintaining clean spaces, supporting good ventilation, coordinating contingency plans and working closely with HR and occupational health.
The most effective approach is not based on one dramatic intervention. It comes from consistent cleaning, well-maintained building systems, clear communication and practical support for employees.
By preparing early, FM teams can help protect workplace wellbeing, maintain operational continuity and create greater confidence throughout the winter months.
