Sexual harassment at work can leave someone unsure whether reporting it will make their working life harder. In the UK, this is not simply a matter of confronting the person responsible. Workers have legal protections, employers have preventative duties, and complaints can lead to formal grievances or tribunal claims. Understanding each route helps you decide what to do next.
What counts as sexual harassment at work?
In England, Scotland and Wales, the Equality Act 2010 defines sexual harassment as unwanted conduct of a sexual nature that violates someone’s dignity or creates an intimidating, hostile, degrading, humiliating or offensive environment. Harmful intent is not always necessary, and one incident can be enough.
Examples include sexual remarks about someone’s body, intrusive questions, unwanted advances, sexual images shared in a work chat and unwanted touching. Harassment can happen during business travel, work events or online meetings. Describing it as “banter” does not make it acceptable.
Context matters, including the person’s experience and whether the effect was reasonable. They need not prove the behaviour was motivated by their sex. Protection can extend to employees, workers, applicants and some people personally engaged to perform work.
Your rights after workplace sexual harassment
You can report harassment without confronting the alleged harasser directly. You may also seek confidential advice before making a complaint. The law protects people against victimisation for making or supporting discrimination complaints. Cutting someone’s shifts or blocking promotion because they complained could create a separate legal problem.
Equality Act claims do not generally require two years’ service. Eligibility still depends on the facts and your working arrangement. Understanding discrimination and victimisation at work can help you recognise different forms of unlawful treatment.
Employer harassment duties: prevention comes first
Since 26 October 2024, employers in Great Britain have had a proactive duty to take reasonable steps to prevent sexual harassment. They should assess foreseeable risks rather than wait for a harassment complaint. Risks posed by customers, clients and other third parties matter too.
Practical measures may include clear reporting routes, effective training, designated contacts, risk assessments and safeguards for people working alone. Employers should also address power imbalances and ensure complaints receive a fair response. A written policy is not enough if known risks are ignored.
The Equality and Human Rights Commission can enforce the preventative duty. A tribunal can increase compensation by up to 25% in a successful qualifying harassment claim if the duty was breached. From 30 October 2026, the legal preventative standard is due to become “all reasonable steps”; that is a forthcoming change, not the rule currently in force.
What to do when harassment happens
Prioritise safety and support
If you are unsafe, leave the situation and seek help. Sexual assault may also be a crime, and specialist services can explain reporting options. You can speak with a trusted colleague, union representative, HR contact or senior manager before deciding how to proceed.
Check your employer’s sexual harassment policy. Informal resolution might be suitable in some situations, but you do not have to try it before raising a formal grievance about serious misconduct.
Preserve useful harassment evidence
Make a dated record of what happened, including the words or actions involved, the location, witnesses and your response. Preserve relevant messages, emails and meeting records lawfully. Record subsequent changes to duties or shifts, particularly if you fear retaliation.
Keep a separate chronology of incidents and management responses. Avoid accessing confidential records without permission. Secret recordings can raise legal and disciplinary issues, and may not be admitted as evidence, so obtain advice first.
Making a formal harassment complaint
A grievance should describe incidents clearly, identify available evidence and explain what action you are requesting. Send it to the person named in your employer’s procedure. Where that person is implicated, ask for another reporting contact.
Your employer should investigate promptly and sensitively, consider evidence from both sides and explain the outcome. They should consider suitable interim safeguards without automatically penalising the complainant. Ask for meeting notes and an outcome in writing, and use the appeal procedure where appropriate.
A guide to raising a workplace grievance may help you structure your account. Remember that an unresolved internal complaint does not stop the legal clock for tribunal proceedings.
Can you take a sexual harassment claim to a tribunal?
In Great Britain, the usual employment tribunal deadline is three months less one day from the act complained of. The calculation can be more complex for continuing conduct. Do not assume an exception will apply because your employer is still investigating.
You generally need to notify Acas about early conciliation before filing a claim. Timely notification affects the limitation calculation, but filing a grievance does not pause the deadline. Seek advice promptly about employment tribunal time limits.
Depending on the case, compensation may cover financial losses and injury to feelings. Since 6 April 2026, qualifying disclosures of sexual harassment can also fall under whistleblowing protection where public-interest and other legal tests are satisfied. That protection is distinct from ordinary victimisation rules.
A practical example involving a customer
Imagine a restaurant employee receiving repeated sexual comments from a regular customer. Their supervisor dismisses the issue because the customer spends heavily. The employee records dates, submits a written complaint and asks not to serve the customer alone.
The employer should assess the risk and take meaningful preventative action, rather than instructing the employee to ignore it. Whether third-party behaviour supports a particular tribunal claim depends on the circumstances and law applicable at the time; an employer’s preventative duty is not identical to individual liability.
What about Northern Ireland?
The Equality Act framework above applies to England, Scotland and Wales. Northern Ireland has separate equality laws, including the Sex Discrimination (Northern Ireland) Order 1976, and different procedures. Check Equality Commission for Northern Ireland guidance rather than assuming Great Britain tribunal rules apply.
Frequently asked questions
Can one inappropriate comment count as sexual harassment?
Yes. A single incident may meet the definition if the legal conditions are satisfied. Repeated behaviour is not always necessary.
What if my manager is responsible?
Use an alternative reporting route, such as HR, a senior manager or an independent contact specified in the policy. Keep copies of your complaint and responses.
Can I complain without witnesses?
Yes. Your account, notes, messages and surrounding circumstances may be relevant. No eyewitness does not automatically mean there is no case.
Must I finish my grievance before contacting Acas?
No. Internal and tribunal processes have different timetables. Contact Acas or seek advice early to avoid missing a legal deadline.
Conclusion
Sexual harassment at work in the UK calls for practical action, not silence. Document incidents, choose a safe reporting route and watch legal deadlines. Employers must prevent foreseeable risks and handle complaints fairly, rather than relying on policies that are never put into practice.
