Gender reassignment discrimination: an introduction

Transgender people are those whose gender identity or expression doesn’t conform to their sex at birth. The relevant legislation uses the term transsexual, however, this is now considered outdated, and many people prefer to use the term ‘transgender’ or ‘trans’.

Some transgender people decide to live permanently in the opposite sex to their birth sex (gender reassignment or transition). This may involve medical and surgical procedures which can take months or years to complete.

In Great Britain, people are protected against harassment or discrimination in the workplace because of their gender reassignment under the Equality Act 2010. They protect people who are undergoing or have undergone gender reassignment, people who are considering undergoing gender reassignment and people who are incorrectly perceived to be transgender.

In Northern Ireland, protection from discrimination on the grounds of gender reassignment is provided under the Sex Discrimination (Northern Ireland) Order 1976, as amended by the Gender Reassignment Regulations. These laws protect individuals who propose to undergo, are undergoing, or have undergone gender reassignment.

It is not necessary for people to have any medical diagnosis or treatment to gain this protection: it is a personal process of moving away from one’s birth gender to the preferred gender.

What constitutes discrimination?

Unlawful discrimination against a worker because of gender reassignment includes less favourable treatment, such as not offering the worker employment, less favourable terms and conditions, fewer opportunities for promotion and training or dismissal.

A person harasses another if they engage in unwanted conduct related to gender reassignment, which has the purpose or effect of violating the other person’s dignity or of creating an intimidating, hostile, degrading, humiliating or offensive environment.

You may be being harassed on grounds of gender reassignment, if you are:

  • humiliated;
  • subjected to unwanted comments;
  • ignored;
  • excluded.

A lot of people put up with less favourable treatment or harassment, hoping that it will stop. But it usually won’t stop until someone takes action. Harassment on the grounds of gender reassignment is treated as a form of discrimination in Northern Ireland law.

Complaints can be made under the Equality Act or the Northern Ireland order. If you are forced to resign, you may be able to make a constructive unfair dismissal claim. However, wherever possible, you should seek advice before you resign. 

Employer responsibilities

Employers must offer the same opportunities to every employee and treat everyone in the workplace fairly and with respect. 

The ‘public sector equality duty’ requires public-sector organisations to have due regard to the need to eliminate discrimination and promote equality and good relations in the workplace. Find out more about public-sector equality duty

What to do next

If you think you are being harassed or otherwise discriminated against because you are transgender, or because someone thinks you are, you may want to raise matters.
  • 1 Begin by keeping a record of incidents and contact your UNISON representative. Talk to the person who is discriminating against you or ask someone else to talk to them to see if you can resolve the issue informally.
  • 2 If you can’t resolve the issue informally, you can raise an informal grievance using your employer’s grievance procedure.
  • 3 You should be aware that strict time limits apply to making a tribunal claim. At the moment in Great Britain, this is three months less one day from the act of discrimination, but it is anticipated that the time limit will increase to six months less one day from October 2026.
  • 4 In Northern Ireland, the time limit for bringing a discrimination claim is three months exactly from the date of the act complained of. Conciliation is provided by the Labour Relations Agency (LRA), not ACAS.
