Managing Long-Term Absence: A Practical Guide for Employers

From everyday illnesses to winter bugs, it’s to be expected that every employee will need the occasional sick day here and there. In most cases, a short period of rest will be enough to help a person recover and get back to work. But what happens when circumstances change and what began as a brief absence gradually turns into something far more serious.

Long-term absences are much more common than you’d think; in fact, a report by the Commission for Healthier Working Lives found that up to 300,000 people each year are forced to leave the workforce due to extended ill health. This highlights the importance of having effective absence management practices in place to ensure employees receive the right support.

So how should you manage long-term absence? And how can you balance business needs with employee wellbeing? The team at Healthier Workforce is here to explore this issue.

What is classed as a long-term absence?

There isn’t an official definition for what constitutes a long-term absence, and this can vary from business to business. However, most employers will consider any absence that lasts four weeks or more to be long term, and this is also the threshold used by ACAS.

The most common causes of long-term absences can typically be split into the following broad categories:

• Mental health conditions: Stress, anxiety, burnout, PTSD, etc
• Chronic conditions: Diabetes, epilepsy, Crohn’s disease, rheumatoid arthritis, COPD, etc
• Serious illnesses or injuries: Cancer, heart attack, stroke, post-surgery recovery, etc
• Musculoskeletal issues: RSI, back pain, joint conditions, etc
• Word-related injuries or illnesses: HAVS, asbestosis, occupational asthma, etc

Why does long-term absence management matter?

A long-term absence in your team can have a huge knock-on effect on your business operations, as well as the rest of your employees. Having effective strategies in place to help manage such absences has a whole host of benefits, including:

• It boosts morale: It’s easy for employees to feel like a cog in the machine, especially if they work as part of a large team. When clear, caring absence management strategies are in place, this sends a strong message that the business genuinely values and supports their staff’s wellbeing, which can boost morale, productivity and trust.
  
• It reduces disruption: An unmanaged absence can quickly put pressure on the rest of the team, creating uncertainty around deadlines, workload and capacity. Implementing a structured absence management plan helps employers to plan ahead, minimise disruption and fairly redistribute responsibilities if necessary.
  
• It prevents reputational damage: How a business treats its employees during a difficult time doesn’t go unnoticed, and poorly handling such situations can affect how both current and future employees view you. This could cause reputational damage that leaves you struggling to recruit or retain top talent.
  
• It minimises the risk of legal action: Under the Equality Act 2010, employees are protected if they have a long-term health condition that meets the definition of a disability. This means that employers are required by law to make reasonable adjustments to help the employee in question to remain in or return to work. Failing to do so could leave you open to legal action and claims of discrimination and unfair dismissal, so having a fair, consistent approach is essential.

What’s the limit on sick leave?

In the UK, there is no legal cap on the amount of sick leave a person can take. However, this doesn’t mean it’s a free-for-all; many employers will set their own thresholds, which should be clearly outlined in the employee’s contract.

If you’re unwell, you should be able to self-certify your illness for the first seven days, which means that no formal medical evidence is required. However, any absence lasting more than seven consecutive days will require a Fit Note from a relevant medical professional as proof. The Fit Note will state how long it applies for, and the duration can vary depending on the nature and severity of the condition in question. During the first six months of illness, a single Fit Note can last for a maximum of three months at a time, and they must be reviewed and renewed regularly to reflect any changes in the employee’s ability to work.

When should occupational health be involved?

If you’re managing an employee on long-term sick leave then it’s best practice to involve occupational health as early as possible – ideally once the absence has exceeded four weeks and is officially classed as long term. The sooner an occupational health practitioner is brought in, the better placed everyone will be to fully understand the situation and create a plan that supports a successful return to work.

While it’s always helpful to consult an occupational health practitioner, their input is invaluable in the following circumstances:

• When the long-term prognosis is uncertain and it’s not clear whether an employee will be able to return to work.
• When reasonable adjustments need to be identified.
• When an employee is demonstrating early symptoms of an occupational disease.
• When the reason for the absence is unclear, complex or involves multiple contributing factors.
• When a return to work is being planned.

How to manage a long-term absence

It’s to be expected that managing a long-term absence may come with some challenges, but having a structured, consistent approach in place will ensure the best results for both the employee and the employer. So how do you manage a long-term absence?

• Document the absence: When an employee first notifies you that they’ll be absent due to illness, you must ensure this is properly documented so that you can begin to create a timeline. Put a clear absence reporting procedure in place – such as notifying a line manager by a set time – and ensure that every employee is aware of this process.
  
• Request a Fit Note: If your employee is absent for more than seven consecutive days, the next step is to request a Fit Note; this must come from a relevant medical professional, such as their GP. Be sure to make a note of the dates the Fit Note covers so you can set a reminder to review this or request an updated note where necessary.
  
• Maintain regular communication: When an employee goes on sick leave, it’s important to maintain regular contact so they don’t feel isolated and supported. At the same time, you don’t want to bombard them with questions or check in with them too frequently, as this can interrupt their recovery, so finding the right balance is important. Agree on a clear communication plan from the outset and schedule periodic check-ins to see how they’re doing and ensure they’re getting the appropriate support.
  
• Refer to occupational health: Once an absence has passed the four-week mark, it’s time to get occupational health involved. An occupational health practitioner can help to assess an employee’s fitness for work, identify any potential stumbling blocks ahead of time and recommend practical adjustments. Crucially, it’s their job to provide impartial support to both the employer and the employee alike, ensuring a smooth process for everyone.
  
• Conduct an absence review meeting: At an appropriate point during their absence, arrange an official review meeting with the employee to talk through how things are progressing. This can take place in person or online if the employee is unable to come into the workplace. Explain the purpose of the meeting in advance so that your employee doesn’t feel ambushed, and be sure to remain understanding and professional throughout.
  
• Develop a return-to-work plan: Once your employee feels ready and has been medically cleared to return to work, consult with HR and an occupational health practitioner on the most appropriate approach to take. Rather than your employee returning to normal hours straight away, which risks overwhelming them and undoing their progress, a phased return to work will likely be recommended.
  
• Consider reasonable adjustments: Following an occupational health assessment, certain reasonable adjustments may be suggested to help support the employee’s recovery. This might include hybrid working, flexible or reduced hours, or changes to their duties, and it’s important to review these adjustments regularly to ensure they remain appropriate.
• Host a return-to-work meeting: On your employee’s first day back, they should be welcomed with a return to work meeting. This is your opportunity to set out the plan for their return, check in on how they’re feeling and bring them up to speed on any changes within the business since their absence. It also offers the employee an opportunity to ask questions and raise any concerns.
  
• Hold regular review meetings: The support shouldn’t stop as soon as your employee returns to the workplace; instead, you should schedule regular check-ins to monitor how they’re settling in, assess whether the return-to-work plan is effective and address any concerns before they escalate.
  
• Explore alternative options: There are some circumstances where, despite all your efforts and support, an employee is genuinely unable to carry on in their previous role. In such cases, the employer has an obligation under the Employment Rights Act 2025 to consider suitable alternatives, such as adjusting their responsibilities or redeploying them to another role.
