Sickness absence has long been treated as an HR problem, something to be managed through policies, trigger points and return-to-work interviews. But the scale of the challenge now and the evidence of what moves the dial, suggests that framing is overdue for revision.
The organisations making the most meaningful progress aren’t doing so by tightening their absence policies. They’re doing it by treating absence as a leading indicator of how well their workforce is functioning – and building the strategy around that insight.
The scale of the problem
Sickness absence has become most complex challenges on the workforce agenda.
Organisations looking to make real progress need to transition away from reactive, lagging measures towards something more proactive. This means spotting risk earlier, giving managers the confidence and tools to act on it, and using flexibility as a genuine lever rather than an afterthought.
For anyone responsible for workforce cost, productivity or employee experience, this isn’t a side issue, but increasingly central to a sustainable workforce.
Sickness absence in numbers
The latest CIPD reports show that sickness absence rates now sits at a 15-year high – and in April 2026, the rules around Statutory Sick Pay changed the cost equation again. Other respected bodies have published their own findings with tell a consistent story:
- According to ONS data, 148.8 million working days were lost to sickness or injury in 2025, representing, on average, 4.4 days lost per worker.
- The CIPD reported that absence rates now sit around 50% higher than before the pandemic at 9.4 days on average compared to 5.8 days.
- The HSE’s own figures show 40.1 million working days lost specifically to work-related ill health and injury in 2024/25.
Mental health remains the single biggest driver. HSE data shows 22.1 million working days were lost to stress, depression or anxiety in 2024/25 alone. The Keep Britain Working review puts the wider picture in stark terms, showing that 800,000 working-age adults have left employment since 2019 due to long-term sickness.
The financial picture sharpens the urgency. Employers lose an average of £120 per day in profit per absent employee, with the combined cost from absence, presenteeism and turnover now estimated at around £85 billion a year. Individuals who fall out of work in their twenties could lose over £1 million in lifetime earnings compared to those in sustained employment.
For organisations managing absence at scale, this isn’t a niche HR issue. It’s a workforce planning, productivity and financial risk issue that touches every department and has implications wider than individual organisations.
Old sickness absence indicators aren’t enough
If the scale of the problem is well-documented, the question becomes, “why isn’t it improving?” The answer lies partly in the tools most organisations are still relying on.
Lagging indicators – Bradford Factor scores, trigger points, return-to-work interviews – measure what has already happened, after the cost has been incurred and the disruption felt. That approach still has a role. Return-to-work interviews, for example, are essential for helping employees reintegrate and for organisations to manage attendance consistently. But on their own, these tools do little to prevent the next case.
There are two dynamics which compound this. The Keep Britain Working review identified a lack of confidence around disclosure as one of the central barriers to early intervention. MHFA England’s 2026 research found that only 38% of organisational leaders talk openly about mental health, and just 45% of managers have been trained to hold those conversations at all. With nearly 70% of employees saying their manager has as much impact on their mental health as their partner, that is a significant gap between where influence sits and where capability currently exists.
Secondly, there is the issue of presenteeism. Employees who feel unable to raise a health concern early often push through until the issue becomes serious enough to force a longer absence. By the time it shows up in the data, the window for early support has often closed.
The impact of workplace bullying
The working environment itself also plays a role. CIPD’s 2024 Good Work Index found that 25% of the workforce – around 8 million people – had experienced conflict at work, including being undermined, receiving verbal abuse, or facing discriminatory behaviour. Those who had experienced conflict reported both physical and mental health consequences.
Acas estimates the annual cost of workplace conflict to employers at £28.5 billion, including management, resolution and absences. And there is a stark perception gap: 81% of employers believe they do enough to address bullying and harassment, compared to just 36% of employees who have experienced conflict.
The risk, taken together, is goes beyond just high absence rates. It shows there there’s a systemic issue, a workforce that discloses later, recovers more slowly, and is more likely to exit altogether – at significant cost to productivity, retention and organisational capability.
What effective organisations are doing differently
One major UK retailer cut absence rates by 10% in 12 months. The approach combined earlier manager conversations, better use of data to spot risk patterns, and more flexible working arrangements during periods of high employee demand. Each of those levers maps directly to the risks above. Read the full case study here.
Rethinking sickness absence indicators
The most immediate shift is in how organisations read their own data. Rather than waiting for absence rates to climb, effective HR teams are tracking signals that precede absence: overtime patterns, grievance and conflict case volumes, engagement survey results and manager-reported concerns.
Employee relations case management technology that flags trends across teams and locations gives HR the chance to act before a pattern becomes entrenched. This is how the disclosure gap is closed before it becomes an absence problem.
Building manager capability as a genuine intervention
The Keep Britain Working review is explicit that management capability is one of the most powerful levers available. But training managers to hold sensitive early conversations – about mental health, conflict resolution, and managing workload – requires more than a one-day course. It requires clear escalation routes to HR, legal and occupational health expertise, and the confidence that specialist support is available when a conversation needs more than a manager can offer.
Managers who have that framework are better at managing absence and more likely to surface the disclosure gap early, which is precisely where the opportunity to prevent a short-term absence from becoming a long-term case sits. This is also the natural point to address workplace conflict: a manager with the capability to have an early, honest conversation about tension or conduct is more likely to resolve it before it reaches the grievance stage, and before it shows up in the absence data.
Flexibility as a genuine absence reduction tool
Flexibility is often framed as a retention perk, but it has a direct role to play in absence reduction too. A timely example: during major sporting events like the FIFA World Cup, employers have no obligation to give staff time off to watch matches. A blanket “no” approach, however, often results in higher unplanned absence as people simply call in sick instead.
A more flexible response, whether that’s unpaid leave, shift swaps, temporary flexible hours, or even putting the match on in a break room where operationally possible, tends to produce better outcomes for everyone. Handled well, these moments become genuine morale boosters rather than friction points, while keeping operational continuity intact.
The same principle applies more broadly. Phased returns, adjusted duties and flexible scheduling for those managing long-term conditions all reduce the likelihood of a short absence becoming a long one, and a long one becoming an exit from the workforce altogether.
Building the support infrastructure around it
None of this works in isolation. Sustainable absence reduction depends on having the right infrastructure behind frontline managers, including case management systems that flag risk early, outsourced HR and legal expertise for complex cases, occupational health and wellbeing provision, and training that keeps pace with changing employment law.
With the Keep Britain Working review setting out a “Healthy Working Lifecycle” approach, spanning recruitment through to exit, organisations that already have these elements joined up will be far better placed to adapt as expectations on employers continue to rise.
There isn’t a single silver bullet to reduce sickness absence levels. But by combining earlier conversations, better data, smarter flexibility and the right specialist support, so that issues are caught and addressed long before they show up as a number on an absence report, organisations can be a stronger place to lower absence levels and better support staff when they do return to work, ensuring that short-term absences don’t snowball into long-term cases.
Take the next step
Absence will always be part of managing a workforce. The question is whether it is managed reactively, counted after the fact and chased through trigger-point policies, or whether it is treated as what it really is. An indicator of how well an organisation supports its people, and where the pressure points are building before they become a cost.
The organisations making real progress are doing both: catching issues earlier through better data and more capable managers, and building the flexibility and specialist support to respond effectively when absence does occur.
