Sickness absence has become a familiar feature of NHS workforce discussions. It appears on workforce dashboards, board reports and operational performance reviews across the system. Yet despite significant investment in wellbeing initiatives, Occupational Health provision and attendance management policies, many organisations continue to experience stubbornly high levels of absence.

Perhaps the challenge is not that organisations are failing to act. Perhaps it is that sickness absence is being viewed through too narrow a lens.

Traditionally, absence has been treated as an HR issue. However, growing evidence suggests it is a combination of workforce productivity, operational resilience and employee experience issues.

Recent analysis by Policy Exchange estimates that sickness absence across the NHS equates to more than 80,000 lost employees annually, with a significant impact on productivity, service delivery and patient access. At a time when every NHS organisation is being asked to do more with limited resources, workforce availability has become one of the most important and least understood drivers of organisational performance.

The question many organisations are now asking is not simply “How do we reduce sickness absence?” but rather “How do we create the conditions that enable people to remain healthy, productive and supported at work?”

This distinction matters.

Across the NHS, there is often no shortage of policies, guidance or wellbeing resources. NHS England itself provides a wealth of practical tools covering wellbeing conversations, psychological safety, compassionate leadership and team wellbeing. Yet many organisations continue to struggle to translate these resources into consistent day-to-day practice.

In our experience, the issue is rarely the absence policy itself.

Most NHS organisations already have the key components required to manage attendance effectively. Line managers own attendance management. HR provides policy, guidance and support. Occupational Health offers specialist clinical expertise. It seems simple.

Before implementing solutions, however, organisations must first understand what is driving absence within their own context. Mental health, musculoskeletal conditions, workload pressures, management capability, team culture, policy application and access tosupport can all play a role. The balance will differ between organisations, services and staff groups.

This is why a structured diagnostic approach is often the most effective starting point.

By reviewing absence data, management processes, Occupational Health pathways, policy application and employee experience together, organisations can identify the underlying drivers of absence rather than simply responding to symptoms. This provides a clear basis for prioritising interventions and focusing effort where it will have the greatest impact.

The challenge then is ensuring the three elements of line managers, HR and Occupational Health are all sighed on this diagnostic approach and able to work together as an integrated system rather than as separate functions. When organisations achieve this alignment, the conversation shifts from managing absence to supporting attendance.

Managers become better equipped to have early and constructive conversations. Occupational Health becomes a proactive partner rather than a reactive referral service. HR teams focus less on process escalation and more on workforce outcomes. Importantly, this does not require major structural redesign or significant investment.

NHS organisations can make meaningful improvements through relatively simple interventions:

• Rigorous data collection and analysis including identifying hotspots and trends
• Capture of “early warning” data – for example, lateness due to sickness (which might not otherwise have been recorded)
• Clarifying manager responsibilities and escalation routes
• Strengthening return-to-work processes
• Improving referral quality and utilisation of Occupational Health
• Introducing more consistent and structured attendance reviews
• Building manager confidence through practical training and support

Ultimately, improving workforce availability is not about creating more processes or introducing another initiative. It is about helping the existing system work more effectively.

As NHS organisations continue to pursue productivity improvements, workforce transformation and better employee experience, workforce availability deserves greater attention. It represents a significant opportunity to improve operational resilience, reduce pressure on teams and support better outcomes for both staff and patients.

The challenge is not simply reducing sickness absence. It is creating an environment where people can thrive, remain engaged in work and access the right support at the right time. Organisations that achieve this will not only improve attendance; they will strengthen the foundations of workforce productivity and service delivery for years to come.
