Being Dismissed After Returning From Sick Leave: Could This Be Discrimination?
Returning to work after sick leave can be a difficult step. You might still be recovering, adjusting to a new routine, or rebuilding confidence. If you then find that your employer is questioning your capabilities and future at the company, it can feel both unfair and confusing.
Dismissal after sick leave is not automatically unlawful. Employers have to manage absences, and in some cases, they may have legitimate concerns about someone’s ability to continue in their role. However, they still need to act fairly. If the sickness absence is linked to a disability, mental health condition, or long-term illness, discrimination law needs to be considered.
In these cases, instead of simply asking ‘was I dismissed after being off sick?’ the questions are more specific: did the employer consider reasonable adjustments, follow a fair process, and avoid treating the employee unfavourably because of a disability?
Dismissal After Sick Leave is Not Automatically Discrimination
It is important to start with a balanced point. An employer is not prevented from taking action simply because an employee has been off sick. If absence is causing genuine operational issues or if medical evidence indicates the employee cannot return to their role, the employer may have to consider formal steps.
However, this does not mean dismissal is always fair. Before reaching this stage, the employer should look carefully at the facts. They may need to consider reasonable adjustments, alternative roles, and possible support, and explore all possible options before dismissal.
Problems can arise when an employer moves too quickly or treats the sickness absence as an inconvenience. A dismissal might be unlawful if the employer failed to handle the return-to-work process properly or had already decided the outcome before the process began.
When Sick Leave May Be Linked to Disability
A sickness absence may raise discrimination issues if the employee’s condition amounts to a disability under the Equality Act 2010. This can include physical conditions, mental health conditions, chronic illnesses, progressive conditions, neurological conditions and other impairments. The key wording is that the impairment has a ‘substantial’ and ‘long-term’ negative effect on your ability to do normal daily activities.
Many people might not describe themselves as disabled. However, if they have been unwell for more than 12 months and their condition hinders or prevents them from performing everyday tasks, the legal definition may still apply.
When an employer knows or should reasonably know about a disability, they have additional legal duties. They need to consider reasonable adjustments and avoid treating the employee unfavourably because of something arising from their disability. For example, if an employee is dismissed because of an absence directly connected to a long-term health condition, the employer may need to justify the decision and show they acted proportionately.
Reasonable Adjustments Should Be Considered Properly
If a health condition places an employee at a disadvantage at work, the employer may need to consider reasonable adjustments. These are practical changes designed to reduce that disadvantage and support the employee in returning to, or remaining in, work. Adjustments will depend on the role and the health condition. They might include a phased return, flexible hours, remote working, extra breaks, modified targets, or a different way of managing workload.
The important point is that the employer should consider what they can do to help an employee. A reasonable adjustment is not always possible, and an employer does not have to agree to every request. However, they should not dismiss an idea without proper consideration, including the cost of the adjustment, the resources available, and the impact the adjustment would have.
If your employer refused adjustments, it is worth asking why. Did they explain their reasoning? Did they rely on evidence? Did they consider alternatives? Did they speak to occupational health or review medical advice? A refusal may be reasonable in some cases, but it should not be automatic or unsupported.
Absence Triggers Can Sometimes Be Unfair
Many employers have sickness absence policies with trigger points. For example, a certain number of days off may lead to a review, a warning, or a formal process. These policies are common, but can cause problems when disability-related absence is treated exactly the same as ordinary short-term absence. If an employee has been absent due to a disability, the employer may need to consider adjusting the trigger points or discounting certain absences.
This is one area where employees are often told, ‘We have to treat everyone the same’. While this may sound fair, equal treatment is not always enough. If one employee’s absence is linked to a disability, the employer may need to take that difference into account. So, if you were dismissed because of absence triggers, the key issue is whether your employer considered the reason for those absences and whether any adjustment to the policy was required.
Capability Dismissal Must Be Based on More Than Assumptions
Sickness-related dismissals are often described as capability dismissals. This means the employer says the employee is not capable of doing the role. This type of dismissal can be lawful, but it should be based on a fair and informed process. The employer should understand the medical situation, consult with the employee, consider changing the current duties, and review possible adjustments before dismissal. Warning signs of unfair dismissal can include:
- The employer is relying on outdated medical evidence.
- No occupational health referral was made where appropriate.
- A phased return being rejected without a proper explanation.
- The employer ignored evidence that the employee could return with support.
- The outcome appears predetermined.
This is often where unfair dismissal and disability discrimination can overlap. An employer may say that an employee was dismissed for capability, but if the process was rushed or the absence was disability-related, there may be more to consider.
Redundancy After Sick Leave Should Be Looked at Closely
Sometimes an employee returns from sick leave and is told their role is at risk of redundancy. That may be genuine. Being off sick does not automatically protect someone from redundancy. However, redundancy should not be used to remove someone because of their health. If the timing seems suspicious, it is worth looking carefully at the process.
Important questions include: Were disability-related absences counted against you? Were performance scores affected by your condition? Were you given a proper chance to take part in a consultation? Were alternative roles considered? Were other employees treated differently? If the redundancy process relied on absence, performance or availability in a way that disadvantaged you because of a disability, there may be potential discrimination concerns as well as unfair dismissal issues.
Warning Signs That the Dismissal May Be Discriminatory
Every case depends on the facts, but some warning signs prompt closer review. You may have concerns about discrimination if your employer changed their attitude towards you after sick leave, removed responsibilities from you, criticised your performance for the first time, ignored occupational health advice, counted disability-related absence against you, or pushed you towards an exit without discussing alternatives.
It may also be concerning if dismissal was raised very quickly after your return, or if your employer seemed more focused on ending the working relationship than supporting your return to work. These details are important because they can help show whether the employer genuinely followed a fair process or whether your absence or condition influenced the decision in an unlawful way.
If you believe your dismissal after sick leave was unfair or discriminatory, start by gathering key documents. This may include your employment contract, sickness records, occupational health reports, return-to-work notes, grievance correspondence, capability letters, dismissal letters and appeal outcomes. It is also useful to create a timeline. Record when your absence began, what your employer knew about your condition, what medical evidence was provided, what support was requested, what meetings took place, and when dismissal was first mentioned.
