Occupational health (OH) sits at the heart of good people management. One of its main obligations is to assess risks to employees’ health and take reasonable steps to prevent work from causing or worsening ill health.

Employees who experience a supportive, well-managed process during a period of ill health often return with renewed confidence and loyalty. Employers, meanwhile, can benefit from improved retention, reduced absence and stronger morale.

Experts outline common pitfalls and offer their advice on approaches most likely to achieve the best results.

Understand the purpose of OH

Employers may think occupational health is about referring someone when they have been off sick for a long time, but their responsibilities start much earlier than that. Depending on the workplace and the risks involved, employers may also have specific duties around health surveillance.

Bobby Ahmed, an employment law solicitor and Managing Director of Neathouse Partners, explains: “In some roles, ongoing health checks may be required because of exposure to particular workplace hazards.”

Employers also need to respond properly when an individual employee develops a health condition that affects their work. “This can mean obtaining occupational health advice to understand what the employee is capable of doing, whether a return to work can be supported and what changes might help,” he explains. “Where an employee is disabled under the Equality Act, there may also be a legal duty to make reasonable adjustments.”

Don’t wait until a problem becomes serious

One of the biggest mistakes employers make is treating occupational health as a step to take only when a problem has become serious, warns Melanie Stancliffe, Employment Partner at Freeths. She says: “Bringing occupational health into the conversation early, whether that's repeated absence, signs of stress, performance concerns linked to health or requests for workplace adjustments, can help prevent issues escalating and enable employers to make informed decisions.”

Ahmed agrees: “Dealing with the issue early can give both the employer and employee more options.”

Ensure OH reports give you the full picture

Occupational health reports provide employers with independent medical advice on an employee’s health in relation to their ability to work. “Where the frustration often arises is when employers feel that these reports don’t give them the full picture,” says Lisa Patmore, Employment Partner at Dorsey & Whitney.

Employers need to give clear details on what is being asked for, the background and the context. Patmore says: “This includes explaining the purpose of the referral, the specific demands of the employee’s role and the decisions the business is trying to make, whether that be evaluating fitness to return or identifying necessary adjustments.”

Ask the right questions

Occupational health provides medical advice, but the employer remains responsible for deciding what action to take. The employers who get the most from OH are those who treat the referral as an opportunity to understand their employee's needs and to identify practical ways forward, says Emily Ottery, HR consultant at Browne Jacobson.

Once the report comes back, read it carefully. If it is ambiguous, go back with follow-up questions before making decisions, Ottery says.

Employers need wider wellbeing strategy

Don’t assume an OH report will give all the answers. Employers still need to have meaningful conversations with employees, consider medical and workplace evidence as a whole and carefully assess what support may be appropriate.

Occupational health is most effective when viewed as part of a wider wellbeing and people strategy. Stancliff says: “Employers who act early, ask the right questions, properly consider reasonable adjustments and keep clear records are far more likely to support their people effectively while reducing the risk of disputes and costly employment claims."

With increasing focus on mental health, neurodiversity and menopause in the workplace, employers should ensure managers are equipped to recognise when health issues may be affecting performance and know when specialist occupational health advice could help, she adds.

Be supportive

Managing sickness absence is something you do for an employee, not to them. “When a member of staff is absent through illness, there is a real opportunity to demonstrate that the organisation cares,” Ottery says.

“The most effective employers approach these situations with curiosity and compassion, asking ‘how can we help you?’ rather than simply ‘when are you coming back?’ That shift in tone can transform the employee's experience and willingness to engage.”

Employees who feel cared for during ill health are:

• more likely to engage openly,
• more willing to explore return-to-work options, and
• more likely to maintain a positive long-term relationship with their employer. 

Where the illness has a disability dimension, a supportive stance also places the employer on much stronger legal footing.

Invest in your line managers

Good absence management is a supportive framework. “When a manager approaches a return-to-work meeting with empathy and skill, an employee who might otherwise have felt like a burden instead feels valued — and that is often the turning point in a successful return,” Ottery says.

The best OH reports deliver real results when line managers are given the support and guidance they need to implement recommendations effectively. Well-trained managers who feel confident having sensitive conversations can make an enormous difference.

Respect confidentiality

Ottery says ensuring employees are properly informed about what their OH report will contain and who will see it is a powerful way to build trust and encourage open engagement.

Keep in mind that health information can be particularly sensitive, so access should be limited to those who genuinely need it. Ahmed says: “A line manager will often need to understand an employee’s restrictions or recommended adjustments, but that does not mean they need access to their full medical history.”

Use the OH report as a starting point

An OH report will often recommend a phased return, reduced hours, home working, or redeployment. These recommendations are a starting point for a constructive dialogue, not a rigid set of instructions. Ottery says: “Employers have the freedom, and the responsibility, to consider what works best in their particular context.”

The legal requirement under the Equality Act 2010 is for reasonable adjustments, depending on:

• the size of the organisation,
• the nature of the role,
• the cost and practicability of the adjustment, and
• the adjustment’s likely effectiveness. 

“These factors vary not just between employers, but between employees at the same employer. What is reasonable for a large firm with multiple offices and hundreds of staff will differ from what is reasonable for a two-partner practice with three support staff,” says Ottery.

Where you decide not to follow a recommendation, explain why — clearly, and in writing, Ottery adds “This transparency builds trust and demonstrates that the decision has been made thoughtfully.”
