Managing Long-Term Sickness Absence

What Is Long-Term Sickness?

There is no single legal definition of long-term sickness absence, but it is generally understood as any period of continuous absence lasting 4 weeks or more. Some organisations set their own thresholds in their absence management policies, typically ranging from 2 to 6 weeks.

Long-term sickness differs from short-term absence in both its causes and management approach. Common causes include musculoskeletal conditions, mental health issues (such as stress, anxiety, and depression), recovery from surgery, cancer treatment, and chronic conditions.

The key distinction is that long-term sickness requires a structured, supportive management approach focused on rehabilitation and return to work, rather than the attendance monitoring approach (such as the Bradford Factor) typically used for short-term absence patterns.

Statutory Sick Pay (SSP)

Employees who are off sick for 4 or more consecutive days (including non-working days) are entitled to Statutory Sick Pay:

After SSP expires at 28 weeks, the employee may be able to claim Employment and Support Allowance (ESA) or Universal Credit from the government. Many employers offer contractual sick pay above SSP, which is typically more generous but time-limited (for example, 3 months at full pay followed by 3 months at half pay).

It is important to keep the employee informed about when their SSP or contractual sick pay will end, so they can make appropriate financial arrangements and apply for state benefits if needed.

Occupational Health Referrals

An occupational health (OH) referral is one of the most valuable tools available to employers managing long-term sickness. An OH assessment provides an independent, medical perspective on:

• The nature of the employee's condition and its likely duration
• Whether the employee is likely to be able to return to work, and when
• Whether the condition is likely to be classified as a disability under the Equality Act 2010
• What reasonable adjustments could facilitate a return to work
• Whether a phased return or amended duties would be appropriate

You should make a referral when an absence reaches your long-term sickness threshold, or earlier if the fit note suggests a prolonged absence. The employee should be told why you are making the referral and what questions you are asking. They have the right to see the report before it is sent to you and to request amendments if they believe it contains factual errors.

An OH report is not the same as the employee's GP or consultant opinion. OH professionals are specifically trained in workplace health and can provide practical, work-focused recommendations that clinical professionals may not.

Reasonable Adjustments

If the employee's condition amounts to a disability under the Equality Act 2010 (a physical or mental impairment that has a substantial and long-term adverse effect on their ability to carry out normal day-to-day activities), you have a legal duty to make reasonable adjustments.

Common reasonable adjustments include:

• Phased return to work: Gradually increasing hours over several weeks to help the employee build back to full capacity
• Amended duties: Temporarily removing or reassigning physically or psychologically demanding aspects of the role
• Flexible working: Allowing adjusted start and finish times, working from home, or reduced hours
• Workplace modifications: Ergonomic equipment, adapted workstations, or changes to the physical environment
• Time off for appointments: Allowing paid or unpaid time for medical appointments, therapy, or rehabilitation
• Redeployment: Offering an alternative role if the employee cannot return to their current position

What is "reasonable" depends on factors including the size and resources of the employer, the practicability of the adjustment, its effectiveness, and the cost. There is no fixed list — each case must be assessed individually with input from the employee and, ideally, occupational health.

The Capability Process

If, despite support and reasonable adjustments, the employee is unable to return to work or sustain adequate attendance, you may need to consider a formal capability process. This is distinct from a disciplinary process — the employee is not at fault, but the business impact of their absence must be addressed.

A fair capability process typically involves:

• Welfare meetings: Regular check-ins throughout the absence to offer support, update the employee on workplace developments, and discuss any changes to their condition
• Medical evidence: Obtaining up-to-date occupational health reports and, with the employee's consent, information from their treating clinicians
• Formal review meeting: A meeting to discuss the medical evidence, the impact on the business, and what further adjustments or support could be provided
• Considering alternatives: Before making any decision about continued employment, exploring all options including redeployment, further adjustments, and extended leave
• Right of appeal: Any decision must carry a right of appeal, heard by a more senior manager who was not involved in the original decision

Dismissal Risks & Legal Considerations

Dismissing an employee on long-term sickness is one of the highest-risk areas in employment law. To defend a claim of unfair dismissal, the employer must show:

• A genuine reason for dismissal: Usually "capability" (the employee is unable to do the job due to ill health)
• A fair process was followed: Including consultation with the employee, obtaining medical evidence, considering reasonable adjustments, and exploring alternatives to dismissal
• The decision was reasonable: A reasonable employer in the same circumstances would have made the same decision

Additional risks arise under the Equality Act 2010 if the condition is a disability:

• Failure to make reasonable adjustments: If the employer has not explored and implemented reasonable adjustments, a dismissal is very likely to be found discriminatory
• Discrimination arising from disability: Dismissing someone because of something arising from their disability (such as their absence) is unlawful unless it can be objectively justified as a proportionate means of achieving a legitimate aim
• Uncapped compensation: Unlike unfair dismissal (which has a statutory cap), compensation for disability discrimination is uncapped, making the financial risk significantly higher

Given these risks, it is strongly advisable to seek specialist HR or legal advice before proceeding to dismiss an employee on long-term sickness absence.
