The NHS has circulated a ‘flu jab SOS’ for flu season, urging all eligible people to get a free flu vaccination. This follows news from Australia’s having over a 50% increase flu cases compared to last year – a trend that often signals what’s ahead for the UK.

As the colder months roll in, so do seasonal illnesses, and flu season is officially here. For businesses, this is both a health concern and a productivity challenge. Rising cases mean more absences, and without the right support, presenteeism can creep in, putting both wellbeing and performance at risk.

Now is the time for employers to think beyond reactive measures and embrace proactive wellbeing strategies. From promoting flu vaccinations and hygiene awareness to offering flexible work options and mental health support, these steps can help protect employees and keep workplaces resilient through winter’s toughest weeks.

Taking a proactive approach to winter illness

With flu cases rising and new strains of COVID still circulating, businesses must stay alert. On-site flu jabs, regular health updates, and access to employee assistance programmes (EAPs) are powerful tools in keeping teams safe and supported.

A proactive, supportive approach to wellbeing helps employees feel valued and creates a more resilient, productive workplace.

The approach businesses should take is about building trust, loyalty, and long-term resilience. A proactive approach to health means recognising that sick days are unavoidable. When employees feel valued and cared for, they’re more likely to thrive through winter challenges.

Immune System: Building Resilience from Within

A healthy workplace culture goes beyond policies. Businesses can take a preventative health approach by sharing resources on flu prevention, hygiene, and immune-boosting habits to help employees take ownership of their wellbeing. The next step could include wellbeing webinars and making sure employees have knowledge on ways that physical health and nutrition can protect their immune system.

Managers play a key role here in supporting employee wellness. By building a workplace culture that encourages open conversations and offering flexibility, like remote and flexible work options where possible, leaders can reassure employees with any health concerns, help prevent presenteeism and support recovery.

How to support employees with winter health

For employers, winter is a critical time to double down on wellbeing strategies. Vicky Walker, Chief People Officer at Westfield Health, highlights the importance of being proactive: “As flu cases rise this winter, it’s crucial that workplaces prioritise employee wellbeing to help both prevent its spread and maintain productivity.”

Important steps that employers can take to keep a healthy team include:

  • The first line of defence is encouraging employees to stay home at the first signs of illness, whether it’s fever, chills, or a persistent cough.
  • A clear and compassionate sick leave policy helps employees feel safe putting their health first, without fear of repercussions.
  • Use internal channels to keep employees in the loop about on-site flu jabs or offer free flu jab vouchers for employees as well as wellness efforts aimed at reducing the spread.
