Record sickness absence exposes the cost of waiting until employees become ill

Employers could significantly reduce long-term absence by investing in prevention and earlier intervention rather than relying on support once staff are already off work.

New analysis from MetLife UK and YuLife shows that UK employers are facing mounting costs from sickness absence as employees now take an average of 9.4 sick days each year; the highest level recorded in more than 15 years

The report, The Prevention Advantage, argues that while many organisations continue to invest in financial protection once employees become too ill to work, a growing body of evidence suggests businesses should instead focus on preventing health issues from escalating in the first place.

The findings come at a time when average sickness absence has reached its highest level in more than 15 yearsand economic inactivity linked to long-term sickness continues to place pressure on employers and the wider economy. The report cites estimates that poor health now costs the UK economy £212 billion each year, while businesses face increasing costs from long-term absence, reduced productivity and presenteeism.

Mental health remains the leading cause of long-term sickness absence, accounting for 47 per cent of cases, followed by musculoskeletal conditions, cancer and other long-term illnesses. Employees are also estimated to lose an average of 44 productive days each year by working while unwell rather than taking time to recover.

For employers, the financial impact extends beyond sick pay. The report estimates each day of absence costs organisations around £120 in lost profit, while a single long-term absence can exceed £20,000. Despite this, 16 per cent of UK businesses do not monitor absence costs and one in six employers say they do not know what sickness absence is costing their organisation.

The report argues that earlier intervention could significantly improve workforce outcomes. According to MetLife UK, 96 per cent of employees who receive early intervention support remain in or return to work, compared with 30 per cent where no early intervention is provided.

Rather than viewing Group Income Protection purely as an insurance product, the report suggests employers should integrate preventative health support, early clinical intervention and rehabilitation into a broader workforce health strategy. This includes access to virtual healthcare, mental health support, wellbeing platforms and behavioural interventions designed to reduce the likelihood of employees reaching long-term absence in the first place.

The authors conclude that, as workforce health challenges continue to evolve, organisations may need to rethink whether investing primarily in responding to illness is sufficient, or whether preventing poor health before absence occurs will become the defining feature of future workplace wellbeing strategies.
