Gender reassignment discrimination is one of the most searched and least understood parts of the Equality Act 2010. This guide sets out who the protection covers, the five ways discrimination can happen, what the 2025 Supreme Court ruling did and did not change, and what the tribunals have decided. It is written for HR teams, managers and service leads. It explains how the law applies in general and does not give legal advice on your situation.
Who is protected
Section 7 of the Act protects anyone who is proposing to undergo, is undergoing, or has undergone a process, or part of a process, to reassign their sex. Three points follow, and each one catches organisations out:
- No medical step is needed. Changing name, pronouns or presentation can be enough. Nobody has to have had, or be planning, any treatment.
- No certificate is needed. Protection does not depend on a gender recognition certificate.
- Proposing is enough. Someone who has told a manager they plan to transition is protected from that conversation onwards. See what to do first when someone tells you and you have no policy.
Nonbinary and gender-fluid people can be protected too. In Taylor v Jaguar Land Rover an employment tribunal held that a gender-fluid and nonbinary employee was protected under section 7, and found both harassment and direct discrimination. It is a first-instance decision and does not bind other tribunals. A later tribunal, in Lockwood v Cheshire and Wirral NHS Foundation Trust (2025), took a narrower view after the Supreme Court’s For Women Scotland decision: it held that a nonbinary person with no intention of transitioning did not have the protected characteristic. The position is unsettled, so treat both decisions as guides rather than rules. The Taylor explainer covers what it decided and what it did not.
Five ways discrimination happens
1. Direct discrimination. Treating someone less favourably because of gender reassignment: not promoting them, moving them away from customers, ending a contract. The EHRC Employment Code explains that direct discrimination also covers treating someone badly because they are thought to be trans, or because of their association with someone who is.
2. Indirect discrimination. A rule applied to everyone that puts trans people at a particular disadvantage. A dress code that allows no flexibility, or a rule requiring documents to match a birth certificate, are common examples. It is unlawful unless the organisation can show the rule is a proportionate way of achieving a legitimate aim. That is a judgement you have to be able to explain, and it is why defensible decision-making matters. The toolkit lets you test a rule against the situations it will meet and keep a record of your reasoning.
3. Harassment. Unwanted conduct related to gender reassignment that violates someone’s dignity or creates a hostile, degrading or offensive environment. Deliberate misgendering, repeated “jokes” and the old name used on purpose are the usual forms. An employer can be liable for what colleagues do unless it took all reasonable steps to prevent it, so policy, training and prompt action are the defence. Our manager training covers exactly those everyday moments.
4. Victimisation. Treating someone badly because they complained, supported a complaint or gave evidence. This protects colleagues who speak up, not only the person transitioning.
5. Absence for transition. At work, absence connected with transition must not be treated less favourably than absence for sickness or injury (section 16).
What For Women Scotland changed, and what it did not
In For Women Scotland (2025) the Supreme Court held that “sex”, “man” and “woman” in the Equality Act refer to biological sex. For the Act’s sex-based provisions, including single-sex services and spaces, a person is treated according to their sex at birth, whether or not they hold a certificate.
The ruling did not remove or reduce gender reassignment protection. A trans person is still protected from direct and indirect discrimination, harassment and victimisation because of gender reassignment. What changed is how the separate sex provisions operate. That matters most for facilities and single-sex services, covered in workplace facilities for trans employees and what biological sex means in UK law.
Dignity and respect: the floor, not the ceiling
Everything above describes a floor: the minimum the law guarantees every trans person, at work and as a customer. Dignity and respect is what that floor looks like day to day. It is not a stretch goal, a values statement or a matter of anyone’s beliefs. It is the ordinary standard of treatment the law already expects, and most claims arise because it was missed, not because an organisation fell short of something ambitious.
In practice, treating a trans or nonbinary person with dignity and respect means:
- Use the name and pronouns they use. Early slips happen; correct yourself and move on. Getting it wrong on purpose, or making a point of avoiding it, is a different thing.
- Change the records you control without asking for proof. Email, badge, rota, directory, display names. No certificate, letter or medical evidence is needed.
- Don’t ask about bodies, surgery, medical history or former names. None of it is your business, and “I was only curious” is not a defence to a harassment claim.
- Keep their history confidential. It is theirs to share. Do not pass it on “for context” to a new manager, a customer or a colleague.
- Hold everyone to the same standards. Same expectations, same opportunities, same conduct rules, whoever they are.
- Judge banter by its effect, not its intent. The test is whether conduct violates someone’s dignity or creates a hostile environment, not whether it was meant as a joke.
- Don’t make nonbinary people pick from two boxes you could avoid. Offer Mx as a title, and don’t ask for a sex marker on forms that don’t need one.
- Offer facilities; don’t direct them. A universal, self-contained toilet can be offered to anyone; telling one person they must use it is not the same thing.
Beliefs are not the issue here. A colleague is free to hold a gender-critical or any other protected belief; what the floor regulates is conduct. The dignity and respect page goes further into what this looks like on a working day.
Anything above the floor, such as visible allyship, staff networks or awareness events, is headroom: welcome, and worth doing, but a separate choice. Secure the floor first. An organisation that marks Trans Day of Visibility but lets a manager misgender someone every day has the order the wrong way round. The floor is held by line managers, so that is where training pays off first.
What the case law shows
- The protection has deep roots. In P v S and Cornwall County Council (1996) the European Court of Justice held that dismissing someone for undergoing gender reassignment was sex discrimination. UK law built its protection from there.
- Facilities decisions are judged on how they are managed. In Croft v Royal Mail (2003) a phased approach to toilet access during transition was held reasonable. It predates both the 2010 Act and For Women Scotland, so read it for the principle of reasonable management, not the detail.
- Claims against inclusion policies are decided on their actual effect. In Kelly v Leonardo (2025) a tribunal dismissed a gender-critical employee’s claims about her employer’s toilet policy because it had no practical effect on her. The tribunal still criticised the employer for having no consultation and no equality impact assessment.
- Beliefs are protected; conduct is still regulated. Forstater (2021) held that gender-critical belief is protected. Mackereth (2022) shows the limit: a health assessor who refused to use service users’ pronouns lost his claim. Both sides of that line are covered in protected belief and its limits.
What this means for an organisation
Most claims do not start with a policy. They start with a manager who did not know what to do, a complaint that was not logged, or a decision nobody wrote down. The practical defence is the same whichever direction a challenge comes from:
- dignity and respect treated as the everyday floor, not an aspiration
- a clear policy that covers transition at work, facilities and complaints
- managers trained to respond on day one, not to improvise
- concerns logged and escalated consistently
- decisions recorded with their reasons at the time they are made
- an equality impact assessment for anything that changes access
If you are starting from nothing, begin with what to do first. If a complaint has already arrived, see responding to complaints about trans inclusion.
The toolkit is built for this: it stress-tests your policy against the situations that become complaints, gives managers scripts for the moments that matter, and keeps the record of your reasoning. Where the stakes are higher, such as a live claim, a contested facilities decision or a board that needs assurance, consulting works through it with you on your facts, and training brings your managers up to the floor.
