Understanding Long-Term Sick Pay: Employer Responsibilities & Best Practices in the UK

Absence due to illness is a reality that every UK business faces at some point. But when an employee has to step away for weeks-or even months-because of ill health, what are your responsibilities as an employer? Managing long-term sick pay isn’t just about compliance-it’s about supporting your team and keeping your business healthy, too. If the phrase “long-term sick pay” makes you worry about paperwork, processes, and potential disputes, don’t stress-with the right foundation, this is an area you can handle confidently. In this guide, we’ll walk you through the essentials of supporting staff during long-term sickness absence, from setting clear policies to balancing your legal obligations. Let’s break down what counts as long-term sick leave, what your duties really are-and how to create a fair, legally robust process that protects everyone involved.

What Is Long-Term Sick Leave?

First things first: what actually counts as “long-term” when it comes to employee sickness? Broadly, long-term sick leave is when an employee is off work due to illness or injury for an extended period. While there’s no strict legal definition for “long-term” in UK law, most businesses consider absences that last more than four consecutive weeks (28 days) to fall into this category. It’s different to short-term sickness, which is usually seen as anything under this threshold and typically managed with self-certification and standard absence reporting. Why does the distinction matter? Because long-term sickness triggers different processes, support needs, and legal protections-for you and your employee. Having a clear policy to define these boundaries is a key starting point.

Why Is a Long-Term Sick Leave Policy Important?

If you haven’t formalised how you deal with long-term absence, you’re not alone-many smaller businesses rely on ad hoc arrangements. But this can quickly lead to confusion, inconsistency, and even legal risks down the line. Setting out a written policy helps everyone know what to expect and ensures you follow a fair, transparent process. The main purposes of a long-term sick leave policy are:

• Supporting employees’ health and return to work: Showing staff they’ll have support if they fall seriously ill can boost morale and retention.
• Minimising impact on your business: Absence is less disruptive when it’s anticipated and managed with a plan in place.
• Reducing legal risk: Clarity helps avoid disputes connected to sick pay, discrimination, or unfair dismissal claims.

The key? Get your policy in writing-and make sure it’s shared with all employees, ideally as part of your staff handbook or workplace policies.

What Should Be Included in a Long-Term Sick Leave Policy?

A robust long-term sick leave policy doesn’t have to be long or complicated, but it must be clear and consistent. Here’s what to cover:

1. Clear Definitions

• Set out what’s considered short-term and long-term sickness. Most organisations use four weeks as the cut-off.
• Explain the difference between self-certification (typically for up to 7 days) and the need for medical evidence thereafter.

2. The Purpose of the Policy

• State that the aim is to support employees back to work wherever possible, and to balance this with business needs.

3. Reporting and Communication

• Detail how employees should notify you of sickness, and how you’ll keep in touch over the course of a long-term absence.
• Include when formal meetings might be held (e.g. after a certain number of days), and how these will be conducted (with empathy and privacy).

4. Medical Evidence & Assessments

• Outline when fit notes from a GP or specialist are required, and that these must be kept up to date for long-term absence.
• Explain your right to request (and cover the cost of) occupational health assessments where appropriate, to help plan a safe return to work or any adjustments needed.

5. Sick Pay Entitlements

• Set out whether you offer enhanced sick pay (‘company sick pay’) or if employees will receive only Statutory Sick Pay (SSP)-and explain the relevant rates and limits.

6. Return-to-Work Procedures

• Include your approach to phased returns, modified duties, and other support, such as reasonable adjustments for disabled employees (in line with the Equality Act 2010).

7. Handling Prolonged Absence

• Briefly outline that if long-term sickness continues, options like redeployment or dismissal (due to incapacity) may be considered, but always with fairness and due process.

Keep your policy under regular review, and take advice if you’re unsure whether it meets current laws or best practice.

Legal Requirements: What Does the Law Say About Long-Term Sick Pay?

While much of your approach will be guided by what’s practical for your business, there are clear legal duties you must follow. Let’s explore the most important ones:

Statutory Sick Pay (SSP)

Almost all employees in the UK are entitled to SSP if they meet the qualifying conditions. As of April 2024, the current rate is £116.75 per week, paid for up to 28 weeks of sickness. SSP is paid:

• From the fourth consecutive day of illness (the first three qualifying days are ‘waiting days’ and are unpaid)
• To employees earning at least the Lower Earnings Limit (currently £123 per week)

If your business offers company sick pay (which may be more generous than SSP), spell out exactly:

• Who is eligible
• The rate of pay
• How long it applies
• Whether it runs alongside or replaces SSP

Remember, employees cannot legally be paid less than SSP if they are eligible. Failing to comply can land you in trouble with both HMRC and employment tribunals.

Fit Notes and Medical Certification

For the first seven days of any absence, employees can self-certify their illness. After this, they’ll need a fit note from a GP (or hospital doctor) to continue receiving sick pay. It’s sensible to:

• State in your policy when and how often fit notes should be renewed
• Store all medical information confidentially, in line with data protection laws (GDPR and Data Protection Act 2018)

Reasonable Adjustments & Discrimination

If an employee’s health issue counts as a disability under the Equality Act 2010, you must make ‘reasonable adjustments’ to the workplace or duties to help them return to, or stay in, employment. Failing to do so can lead to discrimination claims, which can be costly and reputation-damaging.

Dismissal and Fair Procedure

While dismissal for “capability” (when someone is no longer able to perform their role due to ill health) is legally possible, it’s a last resort. You must:

• Show you took reasonable steps to support the employee’s return, including considering alternative roles
• Follow a clear, fair procedure-usually involving meetings, medical assessments, adjustment offers, and warnings
• Consult with the employee, and allow for representation (by a colleague or union rep) at key meetings
• Avoid discrimination by making sure disability and equality laws are observed

Dismissing someone without following these steps can lead to unfair dismissal or discrimination claims. If you’re facing this situation, it’s wise to get expert advice before taking action. See our full guidance on employee capability and termination for more details.

What About Annual Leave and Other Benefits?

It’s a common question: if someone is off long term sick, what happens to their holiday rights?

• Accruing Leave: Employees continue to build up statutory annual leave while off sick. Your internal policy can’t override this legal entitlement.
• Taking Leave During Sickness: An employee can request to take annual leave while they’re off sick (sometimes used for full pay instead of SSP).
• Carrying Over Leave: If someone misses annual leave due to long-term sickness, they are often entitled to carry over up to four weeks of statutory leave into the next holiday year. The exact rules can vary, so check your policy or seek advice.

Be sure your policy matches both the law and practical realities-especially regarding holiday accrual and entitlement for employees on extended absence.

Supporting a Return to Work: What Are Your Options?

Ultimately, the aim of long-term sick leave management is to help your employee return to their job-if it’s safe and practical to do so. There are several ways you can make the transition back to work smoother, minimising risks for both the employee and your business.

Reasonable Adjustments

• Can changes to duties, hours, or the working environment make it possible for the employee to return?
• Do they need specialist equipment, time off for medical appointments, or a phased return?
• If so, document all adjustments in writing and review them regularly.

Reasonable adjustments are not just best practice-they’re a legal requirement under the Equality Act 2010 if the illness/disability warrants it.

Phased and Supported Returns

• A phased return might involve reduced hours, lighter duties, or regular check-ins over a set period.
• Agree these arrangements in advance, and explain how and when a review will take place.

Clear communication makes the process much less stressful for everyone involved.

Monitoring and Ongoing Support

• Schedule catch-up meetings to discuss progress, challenges, or any further support needed
• Keep a written record of all meetings, discussions, and any concerns raised for future reference

You might find it helpful to have a performance management policy that covers sickness absence as part of your wider HR support system.

What Should You Avoid?

Managing long-term sick leave fairly is not just about ticking boxes. Here are a few common pitfalls to watch out for:

• Making assumptions: Don’t jump to conclusions about an employee’s prognosis or readiness to return-always take medical advice seriously.
• Unequal treatment: Inconsistency in how you apply policies can open the door to discrimination claims.
• Poor record-keeping: Failing to record the process puts you at greater risk if disputes arise later.
• Neglecting privacy: Sickness absence and health details are sensitive information-handle all data in line with GDPR and maintain strict confidentiality.
• Forgeting ongoing obligations: Legal responsibilities like annual leave accrual and data protection continue during absence-don’t let them drop off the radar.

Practical Steps for Employers: A Quick Checklist

To recap, here’s a simple step-by-step approach to managing long-term sick pay and absence:

1. Draft a written long-term sick leave policy (and ensure staff know about it)
2. Clarify sick pay rights-both Statutory Sick Pay and any company sick pay enhancements
3. Set up consistent reporting and meeting procedures
4. Collect and store fit notes/medical evidence securely
5. Arrange occupational health assessments when needed
6. Keep clear records of absence, meetings, evidence, and support offered
7. Plan for return-to-work support and adjustments
8. Understand how sickness affects holiday, benefits, or redundancy rights
9. Seek professional advice before taking any dismissal action

If you need help with any of these steps-be it drafting a policy, reviewing employment contracts, or handling a complex return-to-work case-don’t hesitate to seek legal support. You might also want to read up on employment contracts and types of leave to ensure your approach is joined up across all HR areas.

Key Takeaways

• Long-term sick leave usually covers absences longer than four weeks-your policy should define this threshold.
• Employers must clearly state rights to Statutory Sick Pay and any extra company sick pay-for both legal compliance and fairness.
• Always require and store appropriate medical evidence (fit notes) after seven days’ absence.
• Support employees back to work through reasonable adjustments, meetings, and phased returns.
• Continue to accrue annual leave for staff on long-term sick leave, and allow them to carry over unused holiday where legally required.
• Dismissal for long-term sickness is only lawful after you’ve followed a careful, supportive process and made reasonable adjustments.
• Policies need to be fair, consistent, and regularly updated-with advice from employment law experts when needed.
