Discrimination tribunal claims can be some of the most serious and complex claims employers face. They may involve allegations about dismissal, recruitment, promotion, pay, redundancy, sickness absence, disciplinary action, harassment, victimisation or workplace treatment.
Unlike some employment claims, discrimination claims can carry significant financial and reputational risk. They may involve detailed factual disputes, witness evidence, emails, management decisions and the treatment of an employee over a long period.
Employers should not assume that a discrimination claim is weak simply because the business believes it acted fairly. These claims need careful assessment from the start, especially where the employee has already raised a grievance, contacted ACAS, or issued an employment tribunal claim.
If your business has received a discrimination claim, our employment tribunal defence service can help you assess the risk, prepare your response and defend your position.

Discrimination tribunal claims often turn on detail. The tribunal may consider what happened, why decisions were made, how other employees were treated, what managers said, and whether the employer can justify its actions.
These claims may involve protected characteristics such as age, disability, race, sex, pregnancy and maternity, religion or belief, sexual orientation, gender reassignment, or marriage and civil partnership.
Employers should avoid dismissing the complaint as simply “unfair” or “personal”. If the employee links the treatment to a protected characteristic, the business needs to consider the allegation carefully and preserve all relevant evidence.
Many discrimination disputes start with a grievance. An employee may complain about bullying, harassment, unfair treatment, exclusion, promotion decisions, comments made by colleagues, workload, sickness absence or management behaviour.
If the grievance was not handled properly, the employer’s position may become more difficult. The tribunal may look at how the business responded, whether it investigated fairly, and whether the employee was given a reasoned outcome.
Where a grievance mentions discrimination, victimisation, harassment or disability, employers should take extra care. A rushed or dismissive response can create further risk.
If a discrimination claim is issued, the employer will need to respond carefully. The ET3 response should identify the allegations, explain the employer’s position and deal clearly with each claim.
A vague denial is unlikely to be enough. The employer should explain what happened, why decisions were made and what evidence supports the business’s position.
If you need help preparing the response, our ET3 help for employers page explains how we support employers with tribunal responses.
Discrimination cases often depend heavily on documents and witness evidence. Employers should gather relevant material as early as possible.
Useful documents may include:
Employers should also identify witnesses who were directly involved. Their evidence may be important if the case proceeds to a hearing.
Disability discrimination claims can be particularly sensitive. The employee may argue that the employer failed to make reasonable adjustments, treated them unfavourably because of something arising from disability, or dismissed them unfairly because of sickness absence or performance issues.
Employers should check whether medical evidence was obtained, whether adjustments were considered and whether the business properly assessed the employee’s circumstances before taking action.
In some cases, the employer may have had a genuine business concern but still face risk if disability issues were not handled properly.
Harassment and victimisation allegations can be difficult for employers because they often involve workplace conversations, tone, conduct, messages, jokes or complaints about management behaviour.
The employer should consider whether complaints were raised earlier, whether any investigation took place, and whether managers responded appropriately.
It is also important to consider whether the alleged behaviour involved colleagues, managers, customers or third parties. Employers may need to show that they took reasonable steps to prevent unlawful conduct and dealt with complaints properly.
Some discrimination tribunal claims should be defended firmly. Others may carry enough legal or commercial risk that settlement should be considered.
The decision should be based on evidence, witnesses, documents, compensation risk, management time and the business’s wider position. Settlement is not always an admission of fault. It can be a commercial decision to control risk and uncertainty.
However, employers should not make a quick offer before understanding the strength of the claim. A poorly judged offer may encourage unrealistic expectations.
If the claim continues, the employer may need to prepare disclosure, witness statements and submissions for a preliminary or final hearing.
Witness statements should be clear, accurate and consistent with the documents. Managers should avoid exaggeration or speculation. The strongest evidence is usually factual, specific and supported by records.
If the case is likely to proceed to a hearing, our employment tribunal representation for employers page explains how we support employers through the tribunal process.
Discrimination tribunal claims require careful handling from the start. Employers should review the claim properly, preserve documents, assess the evidence and prepare a clear defence strategy.
Where the claim involves disability, harassment, victimisation, dismissal, redundancy, sickness absence or management conduct, specialist advice is usually sensible.
