How occupational health protects the bottom line

Occupational health (OH) has traditionally been described as a preventive function. The WHO healthy workplace framework and model described this preventative role of OH back in 2010, along with a clear business case. While true, this doesn’t always resonate with employers who are under pressure with challenges such as tight labour markets, rising absence, emerging technologies, lowered productivity, and employee turnover. There is little understanding of the impact of health on these challenges and the mitigating role OH can play.

If used effectively, OH is a way to prevent illness before it starts, identify illness early enough to reverse the effects, and prevent ill-health related incidents and injuries alongside integrated wellbeing strategies offering predictive insight into absence risk, early-warning indicators of burnout, and evidence of return on investment.

Working within the employer, OH can help to prevent legal action, prevent enforcement action, help reduce sickness absence costs, improve productivity, reduce employee turnover and training costs, and improve the culture of the organisation, i.e. a risk management tool.

Health is a business risk

Recent findings from the Keep Britain Working (KBW) review highlight the scale of the challenge in the UK. Sickness absence rates have risen, recruitment costs have increased, and many organisations report difficulty retaining staff with long-term conditions. KBW’s central message is that improving workplace health is one of the most powerful levers available to strengthen the labour market and support economic growth.

This creates what appears to be a new narrative for occupational health: preventing workforce disruption, not just illness.

Employers report that:

• Long-term sickness is driving turnover: Difficulty retaining staff with ongoing health conditions.

• Mental health & musculoskeletal (MSK) health top the list: The most common causes of workplace absence.

• Managers feel ill-equipped: To support staff managing health conditions.

• Fear of stigma: Employees often delay disclosing health concerns.

These findings align with ONS and CIPD data showing that sickness absence has reached its highest level in over a decade, with stress, anxiety, depression and musculoskeletal disorders consistently topping the list of causes. For employers, this is a strategic risk affecting capacity, continuity and cost.

What are the preventative functions of OH, and why do they matter?

1. Prevention on entry

This starts by assessing an individual’s health in relation to the role they are undertaking. For example, do they have any health concerns that could affect their ability to perform the role (fitness for work)? Are there any factors that could affect their safety or that of others (safety-critical assessment)? Could they be at increased risk from exposure to workplace hazards?

OH provides employers with advice on fitness for work and, where appropriate and feasible, recommendations for reasonable adjustments or other measures to support the individual.

2. Prevention in work

OH supports prevention throughout an employee’s working life. This can include health surveillance for known workplace hazards, safety-critical medical assessments and vaccination programmes to reduce the risk of infection.

It also involves helping managers recognise potential health concerns, have supportive conversations with employees and understand when an early referral to OH may be appropriate. OH can provide advice on health promotion and prevention, including lifestyle factors and health management, as well as risk reduction, workplace adjustments, disability and capability.

By identifying potential issues early and providing appropriate advice and support, OH can help prevent ill health from becoming a barrier to people remaining healthy and productive at work.

3. Prevention through organisational support

Prevention also happens at an organisational level. OH can contribute to wellbeing strategies, policies and procedures, workplace initiatives and innovation, helping organisations take a more proactive approach to workforce health.

Importantly, OH can use workforce health data and management information to identify trends, provide insights and help organisations understand where preventative action may be needed.

This shifts OH from being viewed solely as a service that responds to health problems to one that can help organisations anticipate risks, prevent ill health and support a healthier workforce.

Prevention and analytics

Employers increasingly rely on analytics to make decisions, yet the KBW review notes that workplace health data is fragmented and inconsistent. OH can provide actionable insights such as:

• Patterns of absence: Trends across teams, sites and roles.

• Ergonomic risks: Where workplace design is driving harm.

• Mental-health triggers: Early-warning indicators across the workforce.

• Job-design issues: Where roles themselves create risk.

• Return-to-work outcomes: What’s working and what isn’t.

Employers often want to intervene earlier on workforce health, but many are unsure what “good” support looks like, defaulting to wellbeing services which, without clinical input, risk becoming performative rather than preventive. OH provides the clarity and structure needed to anchor workplace health in evidence-based practice.

Final thought

Workplace health is a major opportunity to strengthen the labour market and improve productivity. OH is the mechanism that turns that opportunity into reality. For employers, HR leaders and health and safety professionals, the message is clear: prevention is a commercial strategy, and OH is designed to deliver it.
