Sickness Absence and Disability Discrimination

Sickness absence is a routine issue in the workplace, but it becomes legally sensitive when linked to disability. In England and Wales, employers must manage sickness absence fairly while complying with the Equality Act 2010. This includes avoiding discrimination, making reasonable adjustments, and ensuring that absence management procedures do not unfairly disadvantage disabled employees.

Many disputes arise where employees are disciplined, dismissed, or placed on absence triggers because of disability-related sickness. These situations can lead to claims in the employment tribunal for disability discrimination, failure to make reasonable adjustments, and unfair dismissal.

Legal Framework

Equality Act 2010

The Equality Act 2010 protects individuals with disabilities from discrimination in employment. A person is disabled if they have 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.

Key protections include:

• Protection from direct discrimination
• Protection from indirect discrimination
• Protection from discrimination arising from disability (section 15)
• Duty to make reasonable adjustments
• Protection from harassment and victimisation

These protections apply throughout employment, including sickness absence management processes.

How Sickness Absence Intersects with Disability

Sickness absence becomes a legal issue when it is connected to a disability. This includes:

• Long-term health conditions (e.g. cancer, multiple sclerosis)
• Mental health conditions (e.g. depression, anxiety disorders)
• Fluctuating conditions (e.g. epilepsy, arthritis)
• Recovery periods following treatment

Employers must distinguish between ordinary sickness absence and disability-related absence. Failure to do so can lead to unlawful treatment.

Disability Discrimination in Sickness Absence Management

1. Discrimination arising from disability (Section 15)

This occurs when an employee is treated unfavourably because of something arising from their disability, such as:

• High levels of sickness absence
• Reduced attendance due to treatment or flare-ups
• Slower performance linked to health conditions

Example:
An employee with chronic fatigue syndrome is dismissed for excessive absence without consideration of the underlying condition. This may constitute discrimination arising from disability unless the employer can objectively justify the decision.

2. Failure to make reasonable adjustments

Employers have a legal duty to make reasonable adjustments where a disabled employee is placed at a substantial disadvantage.

In sickness absence contexts, adjustments may include:

• Adjusting absence triggers in attendance policies
• Allowing additional sickness absence before disciplinary action
• Modifying return-to-work procedures
• Offering phased returns after long-term sickness
• Changing working hours or duties
• Allowing remote or flexible working

Failure to adjust absence management policies is one of the most common causes of disability discrimination claims.

3. Indirect discrimination in absence policies

Indirect discrimination may occur where a sickness absence policy applies equally to all employees but disadvantages disabled workers.

Examples include:

• Strict “trigger point” systems that penalise disability-related absences
• Uniform absence thresholds without adjustment for long-term conditions
• Attendance bonuses that exclude disabled employees due to unavoidable absence

Such policies may be lawful only if they can be objectively justified as a proportionate means of achieving a legitimate aim.

4. Direct discrimination (less common)

Direct discrimination occurs where an employee is treated less favourably specifically because of their disability.

Examples include:

• Dismissing an employee because they have a disability-related condition
• Refusing to allow sickness absence because it is disability-related
• Treating disabled employees more harshly than non-disabled employees

Direct discrimination cannot generally be justified.

5. Victimisation

Victimisation occurs where an employee is treated unfavourably because they have:

• Complained about disability discrimination
• Requested reasonable adjustments
• Supported another employee's complaint

In sickness absence cases, this may include punitive treatment after raising concerns about absence policies.

Employer Responsibilities in Managing Sickness Absence

Employers must ensure that absence management procedures are fair and compliant with discrimination law. Key responsibilities include:

• Identifying whether absence is disability-related
• Considering medical evidence and occupational health reports
• Applying reasonable adjustments where required
• Avoiding automatic disciplinary triggers for disabled employees
• Ensuring consistent treatment across employees
• Justifying decisions with objective reasoning

Acas guidance emphasises the importance of handling absence sensitively and making adjustments where appropriate to avoid discrimination claims (acas.org.uk).

Return-to-Work Processes and Legal Risk

Return-to-work interviews and procedures are standard practice, but they can create discrimination risk if not handled correctly.

Risks include:

• Pressuring employees to return before they are medically fit
• Penalising employees for ongoing disability-related absence
• Failing to adjust duties after return
• Ignoring medical recommendations for phased return

A fair return-to-work process should consider medical advice and any necessary adjustments.

Capability Dismissal and Disability

Employers may consider dismissal on capability grounds where an employee cannot sustain attendance due to illness. However, in disability cases, strict legal safeguards apply.

Before dismissal, employers should:

• Obtain up-to-date medical evidence
• Consider reasonable adjustments
• Explore alternative roles or duties
• Review attendance policies for fairness
• Assess whether dismissal is a proportionate response

Failure to follow these steps may lead to claims for unfair dismissal and disability discrimination.

Employment Tribunal Claims

Employees may bring claims where sickness absence has been mismanaged in a discriminatory way. Common claims include:

• Disability discrimination
• Discrimination arising from disability
• Failure to make reasonable adjustments
• Indirect discrimination
• Unfair dismissal

Tribunals assess:

• Whether the employer knew or should have known about the disability
• Whether adjustments were considered and implemented
• Whether absence policies were applied rigidly
• Whether dismissal was proportionate
• Whether alternative solutions were available

Compensation may include:

• Loss of earnings
• Injury to feelings
• Future financial loss where employment is affected

Time Limits and Early Conciliation

Most discrimination claims must be brought within three months less one day of the act complained of. This period may be extended through Acas Early Conciliation, which is mandatory before submitting a tribunal claim.

Ongoing sickness absence issues may involve multiple acts, but each must still fall within legal time limits.

Practical Issues in Sickness Absence Cases

1. Medical evidence disputes

Disagreements often arise between employer and employee medical evidence. Tribunals consider occupational health reports but are not bound by them.

2. Hidden disabilities

Some conditions are not immediately visible (e.g. mental health conditions). Employers may still be liable if they should reasonably have been aware of the disability.

3. Attendance management systems

Rigid systems that automatically trigger warnings or dismissal are high risk if they do not account for disability.

4. Workplace culture

Pressure to avoid absence reporting or to return early can contribute to discrimination claims.

Common Questions

Is sickness absence always protected under discrimination law?

No. Protection applies when the absence is linked to a disability as defined under the Equality Act 2010.

Can an employer dismiss someone for long-term sickness?

Yes, but only after considering reasonable adjustments and ensuring a fair process.

Do employers have to ignore sickness absence records for disabled employees?

No, but they must adjust policies to avoid disadvantage where required.

Is mental health covered as a disability?

Yes, if it meets the statutory definition of long-term and substantial impact.

Final Thoughts

Sickness absence and disability discrimination law are closely connected in UK employment law. Employers must manage absence fairly while complying with the Equality Act 2010, particularly in relation to reasonable adjustments and disability-related absence. Problems commonly arise where rigid absence policies are applied without flexibility or where dismissal decisions are made without proper consideration of medical conditions. Employees who believe they have been treated unfairly may bring claims in the employment tribunal, subject to strict time limits and procedural requirements.
