Practical steps for managing long-term sickness absence

Long term sickness absence continues to be one of the most challenging people issues. It is rarely straightforward, often emotionally charged, and can feel like a balancing act between supporting the individual and keeping the business moving.

Recent commentary across HR Magazine and Personnel Today has highlighted how many employers still struggle with confidence and consistency in this area, particularly where health issues are complex or ongoing. For smaller businesses without in house HR, the risk is not usually intent, but uncertainty.

This blog focuses on practical, proportionate steps that help employers manage long term absence fairly, legally and humanely.

Long-term sickness absence is generally understood as an absence lasting 28 days or more.

At this point, the issue is no longer just about day-to-day cover. It becomes a people management and employee relations matter, with potential implications under employment law, including disability discrimination. Recognising this shift early is key.

Most long-term absence issues escalate because of what does not happen early on.

Avoiding contact altogether
Managers often worry about saying the wrong thing and end up saying nothing. Long periods of silence can leave employees feeling isolated and anxious making eventual conversations harder.

Treating fit notes as instructions
Fit notes are advisory, not prescriptive. They are designed to support a conversation, not replace one.

Delaying difficult decisions
Support and patience are important, but so is clarity. Letting absence drift without structure rarely helps either party.

None of these are about bad intent. They are about a lack of confidence and clear process.

Fit notes are often misunderstood. They explain how an employee’s health affects their ability to work and may suggest adjustments or a phased return.

They do not require employers to implement changes that are not reasonable or practical. However, they do place a responsibility on employers to consider the advice and discuss it with the employee. The value of the fit note is in prompting an open, informed conversation about what might be possible.

Where an employee has a condition that meets the definition of a disability under the Equality Act 2010, there is a duty to consider reasonable adjustments.

Reasonable does not mean unlimited or indefinite. It means taking proportionate steps that help remove barriers to work, taking account of the size and resources of the business.

Examples might include adjusted hours, temporary changes to duties, or a phased return. What matters most is showing that options have been explored thoughtfully and fairly.

Regular, agreed contact is one of the most effective tools in managing long-term sickness absence. This is not about pressuring someone back to work. It is about maintaining connection, understanding how things are progressing, and reducing uncertainty on both sides.

Good practice includes:

• Agreeing how often contact will happen
• Being clear about who will make contact
• Keeping conversations supportive and factual
• Following up discussions in writing

Consistency builds trust and protects the business if decisions are later challenged.

There may come a point where it is unclear if or when an employee will be able to return to work.

At this stage, the focus may shift to capability. This is a structured process that looks at medical evidence, the impact on the role, and whether continued employment is viable.

This is where early advice is particularly valuable. A well-managed capability process is not about rushing to dismissal. It is about making a fair, informed decision based on evidence and consultation.

Supporting employees through ill health is the right thing to do. It also makes commercial sense. Poorly handled absence issues often lead to grievances, claims, or disengagement elsewhere in the workforce.

At the same time, employers are entitled to make decisions that allow the business to function.

Therefore, balance is key. Clear processes, open communication, and timely action protect both the individual and the organisation.

Long term sickness absence is rarely easy, but it does not have to feel unmanageable. With the right structure and support, organisations can handle these situations calmly and confidently.

If your managers are unsure how to approach long term absence, or your policies have not been reviewed recently, now is a good time to act. Getting it right early is always easier than trying to fix things later.

When managed well, this is not just about compliance. It is about trust, fairness and sound decision making when it matters most.
