The biggest growth area in our clinic is occupational health referrals. These are referrals for employees who have been off work sick for a long time, require work adaptations, or whose performance is suffering. Often, on investigation, we find that each of these employees had several opportunities to receive appropriate medical support that were missed either after a health event with little follow-up, or when their symptoms first appeared. We find they have experienced inadequate investigation and diagnosis, as well as inadequate referral and management.

UK employers are dealing with a persistent productivity challenge that rarely shows up neatly on a balance sheet: preventable absence, prolonged recovery times, and employees operating well below capacity because health issues are not addressed early or effectively.

Recent UK data underline the scale of the issue. The Office for National Statistics estimates that 148.9 million working days were lost to sickness or injury in 2024, equating to approximately 4.4 days per worker. Meanwhile, the CIPD’s most recent Health and Wellbeing at Work survey reports an average of 9.4 days of absence per employee per year, the highest figure recorded in over 15 years. While these statistics are measured differently, the conclusion for HR leaders and managers is the same: sickness absence remains one of the most significant and most controllable drains on productivity.

The critical question for employers is not whether employees will become unwell, but whether the healthcare access they rely on supports a rapid, high‑quality recovery and a confident return to work.

NHS dependency & the productivity cost of delayed access

Most UK employees rely almost entirely on the NHS for primary care. While the NHS provides outstanding care in many areas, pressure on GP services means appointment availability can be limited. From an employer’s perspective, this creates predictable problems.

When GP appointments are difficult to secure, employees wait longer to be assessed, symptoms persist, and minor issues are more likely to escalate. Managers are left managing uncertainty around fitness for work, potential contagion, and reasonable adjustments. The result is longer absences, repeated short‑term absences, or presenteeism — employees who are technically at work but functioning well below their usual level.

NHS data show that a significant proportion of GP appointments are booked two weeks or more in advance, with a notable minority booked four weeks or more ahead. For someone with evolving symptoms, that delay alone can extend absence well beyond what would otherwise be necessary.

Why regular GP access improves performance, not just attendance

Regular GP access is often misunderstood as a reactive service, used only when an employee is acutely unwell. In practice, its greatest productivity value lies in prevention and early intervention.

Consistent access to a clinician who can take time, build context, and spot patterns reduces the likelihood that employees struggle on for months with fatigue, headaches, gastrointestinal problems, sleep disruption, hormonal changes, or poorly controlled chronic conditions. These issues rarely trigger immediate sick leave, but they steadily erode concentration, decision‑making, energy and morale.

For employers, this translates directly into reduced presenteeism, fewer repeat absences, and clearer, faster return‑to‑work decisions.

Annual health screening: reducing long‑term absence risk

Annual health screening plays a complementary role. Done well, it is not about medicalising a workforce, but about identifying risk early, before it becomes prolonged sickness absence or long‑term incapacity.

Screening can highlight emerging cardiovascular risk, metabolic issues, nutritional deficiencies, stress load, sleep problems and other factors that commonly affect working‑age adults. Importantly, it also provides employees with a structured opportunity to engage with their health, supported by clinical interpretation and a practical plan.

This matters because longer absences are disproportionately costly. Health and Safety Executive data show that absences related to stress, depression and anxiety average more than 20 working days per case. Early identification and support can materially reduce the likelihood of employees reaching that point.

Limitations of virtual‑only GP models

Many UK employers offer private health insurance to their employees. Still, the missing piece is nearly always access to private GP services that fill the gap in the employee wellbeing package. Insurers offer virtual appointments, but these do not provide continuity of care and are often not helpful for more complex presentations, which end up in the occupational health consultation room.

Short remote consultations can limit clinical depth, especially when physical examination, nuanced discussion, or immediate diagnostics are required. Continuity of care may be limited, with employees speaking to different clinicians each time. In more complex cases, employees are often advised to seek NHS follow‑up for investigations or referrals, reintroducing the same access delays the benefit was intended to avoid.

Virtual care is an effective entry point, but rarely sufficient on its own to resolve the issues that most disrupt productivity.

The optimal model for employers

From a productivity perspective, the most effective approach combines rapid access with depth of care. This typically includes:

• Timely GP appointments, ideally same‑day or next‑day
• Longer consultations when clinically required
• In‑person assessment for persistent or complex symptoms
• On‑site diagnostics to shorten the time to clarity
• Fast-forward referral pathways where appropriate

This model reduces time to diagnosis, speeds up effective treatment, and supports confident, sustainable returns to work.

What HR leaders can implement now?

To translate healthcare access into real productivity gains, employers should:

1. Normalise early access to GP care, rather than waiting until issues escalate.
2. Ensure benefits include in‑person capacity, not just virtual care.
3. Integrate annual screening with structured clinical follow‑up.
4. Measure absence duration and repeat absences, not just frequency.
5. Support managers with clear guidance on adjustments and phased returns.

Health is not a peripheral benefit. It is a core operational input. Employers who invest in timely, high‑quality GP care and meaningful health screening are investing directly in workforce stability, resilience and performance.
