Sexual orientation discrimination

UNISON works to protect the rights of workers who may face discrimination or harassment because of their sexual orientation
Last updated: 21 April 2026

No one should be subjected to unwanted comments, excluded, humiliated or ignored because of their sexual orientation.

People in the UK are legally protected against direct and indirect discrimination, harassment and victimisation in their workplace. 

In Northern Ireland, protection from discrimination on the grounds of sexual orientation is provided under the Employment Equality (Sexual Orientation) Regulations (Northern Ireland) 2003. These protections mirror those in Great Britain, covering direct and indirect discrimination, harassment and victimisation.

If you think you are being harassed or discriminated against, talk to your UNISON rep.

Sexual orientation and discrimination

It is unlawful to discriminate at work because of sexual orientation. Sexual orientation is attraction to people of the same sex (lesbian or gay), the opposite sex (heterosexual or straight) or people of either sex (bisexual).

Less favourable treatment can also occur on the basis of perceived sexual orientation, or where an individual associates with someone of a particular sexual orientation.

The law protects everyone, but it is lesbian, gay and bisexual workers who are most likely to face this type of prejudice and discrimination.

Eliminating discrimination at work ensures everyone has equal opportunities and a fair chance to develop their skills, and is treated with dignity and respect.

In Northern Ireland, similar protection is provided in the Employment Equality (Sexual Orientation) Regulations (NI) 2003. Protection is on the grounds of actual or perceived sexual orientation. 

What counts as harassment?

The most common form of sexual orientation discrimination is harassment, such as prejudiced comments or abuse, exclusion or over-supervision. This includes actions such as homophobic comments made to you, even if you are not and are not perceived to be homosexual. 

Sexual orientation harassment at work occurs when someone engages in unwanted conduct related to sexual orientation which has the purpose or effect of violating a person’s dignity or creating an intimidating, hostile, degrading, humiliating or offensive environment. You may be being harassed if you are:

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

A lot of people put up with harassment, hoping it will go away. But it usually won’t stop until someone takes action.

Complaints can be made under the Equality Act, or the Northern Ireland regulations, if you are being harassed or otherwise treated less favourably because of sexual orientation.

If you are forced to resign, you may also be able to make a constructive dismissal claim which can itself amount to an act of discrimination. However, you should always try and seek advice before resigning. 

Legal protection from discrimination

The Equality Act and the Northern Ireland regulations protect all employees from discrimination at work because of sexual orientation.

It covers all types of employment and workers, including apprentices, those working under contract and the self-employed.

The act and the regulations cover discrimination at work and make it unlawful:

  • for employers to have a rule, policy or practice that, for example, lesbian or gay workers would be less likely to be able to fulfil than heterosexual workers;
  • to treat a worker less favourably because of their sexual orientation, their perceived sexual orientation or because they associate with someone of a particular sexual orientation.

Employers should have a policy that prevents discrimination in recruitment, pay, training, selection for promotion, disciplinary actions or grievances.

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

In Northern Ireland, section 75 of the Northern Ireland Act requires public authorities to have due regard to the need to promote equality of opportunity between persons of different sexual orientations. 

What to do next

If you think you are being harassed or otherwise discriminated against because of sexual orientation, it is advisable to start keeping a written record of every incident. Initially, discrimination may be best addressed informally but there are other things you can do
  • 1 Talk to the person who is discriminating against you or ask someone else to talk to them. If that doesn’t work, talk to your UNISON rep and ask them where you can get support and advice.
  • 2 If you’re still not satisfied, ask your UNISON rep about raising a formal grievance. Tribunal claims are separate from the grievance process.
  • 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. Early Conciliation is provided by ACAS.
  • 4 In Northern Ireland, the time limit for bringing a discrimination claim is three months exactly from the date of the act complained of. Early Conciliation is provided by the Labour Relations Agency (LRA), not ACAS.
