Disability discrimination at work in the UK is not limited to an employer openly refusing to hire someone because of a diagnosis. It can appear in an absence warning, an inaccessible interview, a rigid shift pattern or a manager’s reaction to a request for support. Knowing the rules helps workers recognise problems and employers make fairer decisions.
In England, Scotland and Wales, the Equality Act 2010 protects disabled people throughout recruitment and employment. Northern Ireland uses separate legislation, principally the Disability Discrimination Act 1995, with different procedures and deadlines.
Who is protected by disability discrimination law?
Under the Equality Act, disability generally means a physical or mental impairment with a substantial, long-term adverse effect on normal day-to-day activities. Substantial means more than minor or trivial; long-term usually means lasting, or likely to last, at least 12 months. Cancer, HIV and multiple sclerosis are treated as disabilities from diagnosis.
Protection covers job applicants, employees and qualifying workers, including people with non-visible conditions. Direct discrimination may also involve association with a disabled person or an employer’s mistaken belief that someone is disabled. You do not need two years of service to bring a discrimination claim.
Common disability discrimination examples
Direct and indirect discrimination
Direct discrimination involves less favourable treatment because of disability. For example, a manager rejects a qualified wheelchair user despite accessible interview and workplace arrangements. Indirect discrimination arises when a rule applying to everyone disadvantages disabled people and cannot be objectively justified.
A requirement to attend early-morning meetings might disadvantage someone whose disability involves treatment-related fatigue. The employer should examine whether the rule is necessary and proportionate, and whether changing the meeting time or offering remote access would address the problem.
Discrimination arising from disability
This occurs when someone is treated unfavourably because of something resulting from disability, rather than the disability itself. Examples include penalties for treatment-related absence or extra rest breaks. An employer may have a defence if its action is a proportionate means of achieving a legitimate aim, or it did not know and could not reasonably have known of the disability.
Disability harassment and victimisation
Disability harassment means unwanted disability-related behaviour that violates dignity or creates a hostile, humiliating or offensive environment. Repeated jokes about someone’s mobility or speech may qualify. Victimisation is retaliation connected with a discrimination complaint, such as excluding an employee from training after they support a colleague’s grievance.
Reasonable adjustments: a practical legal duty
Reasonable adjustments are measures to remove or reduce a substantial disability-related disadvantage. In Great Britain, the duty applies when an employer knows, or could reasonably be expected to know, about the disability and relevant disadvantage. Workers do not need to quote the Equality Act to start a discussion.
Adjustments may include an accessible interview, specialist software, a quieter desk, amended duties, extra breaks, a phased return or flexible hours. What counts as reasonable depends on effectiveness, practicality, cost, resources and the employer’s circumstances. An employer should seriously consider alternatives even if the precise request cannot be met.
When attendance scores conceal a disadvantage
Consider someone attending regular hospital appointments whose disability-related absences trigger an automatic warning. Instead of treating the attendance score as decisive, the manager should discuss the circumstances and consider recording or managing those absences differently. Occupational health advice may be useful, but obtaining it should not cause unreasonable delay.
A worker can make a clear written request describing the barrier, its impact and possible changes. Both sides should record their discussion and any agreed review date. Employers should explain rejected proposals and revisit adjustments when duties or health needs change.
Absence, flexible working and promotion decisions
Disability-related sickness absence does not automatically prevent attendance or capability management. But an employer must consider relevant adjustments, alternatives and the risk of discriminatory treatment before issuing warnings or deciding on dismissal. Uniform treatment is not always equal treatment.
Flexible working can itself be a reasonable adjustment. Employees may also use the separate statutory flexible working request process, but refusing that request does not eliminate disability-related obligations. Related guidance on flexible working rights and sickness absence at work can help distinguish these routes.
Promotion, performance assessments, training and redundancy selection deserve the same scrutiny. For instance, counting disability-related absence in promotion criteria without examining adjustments may disadvantage an otherwise suitable candidate. Managers should document why criteria are necessary and what alternatives they considered.
How to challenge disability discrimination at work
Write down the incidents, dates, people involved and practical consequences. Keep relevant emails, policy extracts and attendance records lawfully. If appropriate, discuss the issue with a manager or HR and specify the adjustment or resolution you want. For unresolved concerns, follow the workplace grievance procedure; our guide to raising a workplace grievance explains the usual steps.
An employer should investigate fairly, take complaints seriously and prevent retaliation. If the problem continues, seek advice from Acas, a union representative or an employment solicitor. In Great Britain, notifying Acas for early conciliation is normally necessary before an employment tribunal claim.
Tribunal deadlines changed in October 2026
For most Great Britain employment tribunal claims involving events on or after 1 October 2026, the deadline is six months minus one day. For most discrimination occurring before that date, the deadline was three months minus one day. Time limits can be complicated for repeated incidents. Timely Acas early conciliation can pause the clock, but an internal grievance does not.
Northern Ireland has different procedures, and employment disability discrimination claims generally have a three-month time limit. Anyone considering legal action should confirm their own deadline promptly instead of assuming the Great Britain rules apply.
Frequently asked questions
Does my employer have to know about my disability?
For reasonable adjustments and discrimination arising from disability, what the employer knew or reasonably should have known is relevant. Explaining barriers in writing can help, although employers may also need to make reasonable enquiries when circumstances suggest a disability.
Can disability-related absence lead to dismissal?
Possibly, but dismissal must be assessed carefully. Employers should consider adjustments, alternatives and any legal justification before taking action. The outcome depends on the evidence and individual circumstances.
Who pays for reasonable adjustments?
Employers must meet their reasonable adjustment duties without charging disabled workers for required adjustments. Schemes such as Access to Work may provide additional help, but do not replace the employer’s legal responsibilities.
Can I report disability-related jokes informally?
Yes. Informal reporting may resolve some concerns, while serious or repeated conduct may warrant a formal grievance. Neither approach should cause you to overlook a tribunal deadline.
Fair treatment requires more than a written policy
Disability rights become meaningful when employers examine specific barriers, listen to affected workers and properly consider adjustments. Workers should raise concerns early, keep clear records and seek timely advice. Practical action often prevents a disagreement from becoming a legal dispute.
