6 Ways to Reduce Sick Leave in the Workplace

Reducing staff sick leave remains a key priority for employers. Respiratory illnesses such as influenza are a leading cause of winter absence. The Ministry of Health confirms that influenza can cause several days off work for healthy adults and more serious complications for vulnerable people. Planning ahead before the winter can significantly reduce disruption to workflow and productivity. Below are six practical, evidence based ways to support healthier teams and reduce sick leave.

1. Provide Workplace Flu Vaccinations

You guessed it… workplace flu vaccination programmes are one of the most effective strategies for reducing staff sick leave. The Ministry of Health advises that annual influenza vaccination lowers the risk of severe illness, hospitalisation, and complications. Even in seasons where circulating strains vary slightly, vaccination still reduces severity and duration of illness.

Influenza vaccination takes around two weeks to build effective immune protection. In New Zealand, flu activity usually increases from May and peaks during winter. Encouraging staff to be vaccinated in autumn ensures protection is in place before virus circulation rises.

Offering vaccinations onsite at your workplace removes common barriers such as booking delays, travel time, and lost productivity. Funding vaccination for staff increases uptake and demonstrates commitment to employee wellbeing. Higher vaccination coverage within a workplace reduces the likelihood of rapid spread between colleagues, particularly in shared office spaces, open plan environments, and customer facing roles.

2. Promote a Stay Home When Sick Culture

Attending work while unwell increases transmission risk. Health New Zealand advises people with flu like symptoms such as fever, cough, sore throat, or body aches to stay home until they recover.

Clear workplace policies that support appropriate sick leave reduce pressure on staff to attend work while contagious. Managers and team leaders play an important role by modelling responsible behaviour. Encouraging staff to prioritise recovery reduces the likelihood of workplace outbreaks that result in larger numbers of absences.

3. Improve Workplace Hygiene Practices

Influenza spreads through respiratory droplets and contact with contaminated surfaces. Practical hygiene measures reduce transmission risk. Employers can implement:

• Accessible hand hygiene stations, including hand sanitiser in shared areas, meeting rooms, reception spaces, and break rooms to encourage regular use throughout the day
• Clear reminders about effective hand washing techniques and cough etiquette, reinforced through signage and internal communications
• Routine cleaning and disinfection of high touch surfaces such as door handles, lift buttons, keyboards, shared equipment, and kitchen facilities
• Improved ventilation in enclosed spaces, including regular airing of meeting rooms and assessment of mechanical ventilation systems where applicable

The Ministry of Health promotes hand hygiene and respiratory etiquette as key infection prevention measures during the New Zealand Flu Season.

4. Support Flexible Working for Office Staff

Flexible working arrangements can reduce close contact during peak illness periods in office environments. Hybrid or remote options lower exposure risk, particularly when influenza activity is high in the community.

If a team member develops mild symptoms but remains well enough to work, remote access allows continuity without exposing colleagues. Gradual return to the office after recovery also reduces relapse and supports sustainable productivity. This approach is particularly relevant for administrative and professional roles.

5. Promote General Health and Wellbeing

Strong overall health supports immune function and recovery. Employers can promote practical wellbeing initiatives such as:

• Encouraging adequate sleep through balanced workloads and realistic deadlines
• Promoting access to healthy food options in workplace kitchens or events
• Supporting physical activity through flexible schedules or wellbeing challenges
• Providing access to employee assistance programmes for stress management

WorkSafe New Zealand recognises the connection between worker wellbeing and performance. Supporting staff wellbeing contributes to resilience during winter months.

6. Clear Communication During Flu Season

Clear and consistent communication supports early action. Staff benefit from knowing:

• When the flu season begins and when local cases are increasing
• Common symptoms of influenza and when to stay home
• How and where to access workplace vaccination programmes
• gGuidance for protecting vulnerable family members at home

Providing trusted information from Health New Zealand and the Ministry of Health reduces confusion and encourages informed decision making. Access frequently asked questions and other resources here.

Stay Safe this Winter

Reducing staff sick leave requires a layered approach. Vaccination reduces severity and spread. Early timing strengthens protection. Hygiene practices lower transmission. Supportive policies prevent wider outbreaks. Flexible work options limit exposure. Wellbeing initiatives strengthen resilience. Clear communication ensures staff understand their role in prevention.

Workplaces that act early before winter peaks are better positioned to maintain productivity and protect their teams. Contact Onsite Health to book your workplace flu vaccinations and take a practical step towards reducing staff sick leave this year.
