Being treated unfairly at work because of your sex is something no one should have to put up with, and the law in England and Wales is clear that this kind of conduct has no place in the modern workplace. If you believe you have been sidelined, harassed, paid less, or pushed out because of your sex, the Employment Tribunal is the forum where these disputes are heard. The process can feel daunting, the time limits are tight, and the evidence you gather early on often shapes the outcome. This guide walks through how sex discrimination is defined under the Equality Act 2010, the different ways it can show up at work, and the practical steps involved in bringing a claim. It is written for people trying to work out whether what they have experienced crosses the legal line and what they can realistically do about it.

Overview

A sex discrimination claim is a legal action brought by an employee, worker, job applicant, or in some cases a contractor, against an employer who has treated them less favourably because of their sex. The governing statute is the Equality Act 2010, which consolidated earlier anti-discrimination laws and treats sex as one of nine protected characteristics.

Claims are heard by the Employment Tribunal rather than the ordinary civil courts, and the tribunal has the power to award compensation, make recommendations, and issue declarations about the rights of the parties. Unlike most civil claims, there is no cap on the compensation available for discrimination, and awards can include sums for financial loss, injury to feelings, and in some cases personal injury.

Sex discrimination covers men, women, and in some contexts this area of law also intersects with protections for gender reassignment, pregnancy, and maternity. Before a claim reaches the tribunal, claimants must first notify Acas so that early conciliation can be attempted.

Key steps

  1. Identify the type of discrimination you have experienced. Work out whether what happened fits direct discrimination, indirect discrimination, harassment, or victimisation. Each category has its own legal test, and the evidence you will need differs. Writing down a timeline of events, with dates, names, and what was said, is a useful starting point and will help later if you speak to an adviser.
  2. Raise the issue internally where appropriate. In many cases it is sensible to use the employer's grievance procedure before taking formal action. This creates a paper trail, gives the employer a chance to respond, and can sometimes resolve matters without a tribunal claim. Keep copies of everything you send and receive, and make notes of any meetings you attend.
  3. Contact Acas to start early conciliation. Before you can issue a tribunal claim, you are legally required to notify Acas, who will offer free conciliation to see if the dispute can be settled without a hearing. This step pauses the clock on your time limit. Even if conciliation does not resolve things, you will receive a certificate which you need to bring a claim.
  4. Submit your ET1 claim form within the time limit. Tribunal claims for sex discrimination generally must be brought within three months less one day of the act complained of, though this period is extended by the Acas conciliation process. The ET1 form is submitted online through the gov.uk tribunal service. Be careful to include every act of discrimination you want to rely on.
  5. Prepare for case management and the hearing. Once the employer files its response on an ET3, the tribunal will set directions for disclosure of documents, witness statements, and a final hearing. This is often the most demanding stage. Gathering supporting evidence, identifying witnesses, and thinking carefully about the losses you are claiming all become important, and many people find it helps to get guidance at this point.

Common questions

Q What is the time limit for bringing a sex discrimination claim?
You generally have three months less one day from the date of the discriminatory act to start a claim, though this is extended while you are in Acas early conciliation. If the discrimination is a continuing course of conduct rather than a one-off event, time runs from the last act in the series. Tribunals can extend time in limited circumstances where it is just and equitable, but you should not rely on this.
Q Do I need to have left my job to bring a claim?
No. You can bring a sex discrimination claim while you are still employed, and many claimants do. The law protects job applicants, current employees, workers, and in some cases people who have already left, so your employment status does not prevent you from taking action. That said, thinking through the practical implications of claiming against a current employer is worthwhile before you start.
Q How much compensation can I receive?
There is no upper limit on compensation for discrimination claims, which is one of the key differences from ordinary unfair dismissal. Awards typically include financial losses such as lost earnings, plus a separate sum for injury to feelings. The injury to feelings element is assessed using bands set out in case law, with the range depending on how serious and prolonged the conduct was.
Q What is the difference between direct and indirect discrimination?
Direct discrimination is when someone is treated less favourably specifically because of their sex, for example a woman being paid less than a man doing the same role. Indirect discrimination is more subtle: it happens when a neutral rule or practice puts people of one sex at a particular disadvantage and cannot be objectively justified by the employer as a proportionate means of achieving a legitimate aim.
Q Is sexual harassment the same as sex discrimination?
Sexual harassment is a specific form of prohibited conduct under the Equality Act 2010 and sits alongside sex discrimination rather than being identical to it. It covers unwanted conduct of a sexual nature, and also unwanted conduct related to sex that violates someone's dignity or creates a hostile environment. Both types of claim can be brought in the Employment Tribunal and often arise together.
Q Do I need a solicitor to bring a tribunal claim?
No, you are not required to have legal representation, and many people represent themselves. That said, discrimination claims tend to be among the more complex tribunal cases, with detailed evidence and legal tests to navigate. Getting guidance early on, even just to talk through your situation, can help you decide whether you have a viable claim and how to approach it.
Q What happens if my employer dismisses me for complaining?
Being treated badly because you raised a discrimination complaint, or supported someone else's complaint, is called victimisation and is itself unlawful under the Equality Act 2010. Dismissal in those circumstances can give rise to a separate claim for victimisation, and potentially an automatic unfair dismissal claim as well. Keep written evidence of the original complaint and the employer's response.
