How to manage long-term sickness absence

Long-term sickness absence requires careful management. Dismissing a long-term sick employee without following the right process is a common source of unfair dismissal and disability discrimination claims.

📜 Employment Rights Act 1996, Equality Act 2010📖 ACAS guidance on absence management
Guidance note: This guide sets out standard best practice based on the ACAS Code of Practice and current UK employment law. It is guidance, not legal advice. For complex or high-risk situations, consult an HR specialist before acting.
Step-by-step process

Maintain regular, supportive contact with the employee throughout their absence. This does not mean pressuring them to return — it means keeping the line of communication open, showing that you value them, and keeping them informed of any workplace developments. Agree a communication plan with the employee (frequency, method, who will make contact).

💡 Tip: Regular contact often helps employees feel connected and can speed up their return. Lack of contact can make returning feel daunting.

Request a fit note (GP certificate) after the first 7 days of absence. For longer absences, consider requesting a medical report from the employee's GP or an independent occupational health (OH) assessment. To request a GP report you need the employee's written consent under the Access to Medical Reports Act 1988. An OH assessment can provide practical guidance on adjustments that might facilitate a return.

Legal basis: Access to Medical Reports Act 1988: employees have the right to see and comment on any GP report before it is sent to you.

If the employee's condition may amount 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 duty to make reasonable adjustments. Dismissing a disabled employee without first considering and implementing reasonable adjustments is likely to be disability discrimination.

Legal basis: Equality Act 2010 s.20 and s.21: the duty to make reasonable adjustments. Failure to comply is unlawful disability discrimination.
Watch out: Many conditions that are not traditionally thought of as disabilities — including depression, anxiety, chronic pain, and cancer — are likely to be disabilities under the Equality Act. Always take medical advice before concluding that the duty to make adjustments does not apply.

Hold periodic welfare meetings with the employee (with their agreement) to discuss their health, prognosis for return, and any support the employer can offer. These meetings are supportive — not disciplinary. The employee may bring a companion. Document the meetings carefully.

Before considering dismissal, explore whether reasonable adjustments could enable the employee to return. Adjustments might include: a phased return to work; reduced hours; different duties; different location; working from home; or specialist equipment. Adjustments should be reviewed and updated as the employee's condition changes.

If, after a reasonable period of absence and all reasonable adjustments have been considered, the employee is still unable to return and there is no reasonable prospect of return in the foreseeable future, you may consider a capability hearing. Write to the employee inviting them to a hearing to discuss their continued employment. They have the right to be accompanied. At the hearing, discuss the medical evidence, adjustments considered, alternatives explored, and whether dismissal on grounds of capability is now appropriate.

Watch out: Do not dismiss a long-term sick employee without first obtaining up-to-date medical evidence about their prognosis and without genuinely considering adjustments. Dismissal without this process is very likely to be unfair.

If dismissal on grounds of capability is the outcome, confirm this in writing with: the reason (capability/ill-health); the notice period; the last day of employment; details of any ill-health/incapacity benefit entitlement under the contract; and the right of appeal. Where the employee is disabled, document all adjustments considered and why they were not sufficient.

⚠ Common mistakes to avoid
Dismissing without obtaining up-to-date medical evidence
Failing to consider reasonable adjustments before dismissal
Not treating the employee's condition as a potential disability
Cutting off contact with the employee during absence
Dismissing too quickly without allowing a reasonable period for recovery
