What is workplace harassment?

Harassment at work is unwanted conduct related to a protected characteristic that violates your dignity or creates a hostile, degrading or offensive environment.

Under the Equality Act 2010, protected characteristics include:

  • Age.
  • Disability.
  • Gender reassignment.
  • Marriage or civil partnership.
  • Pregnancy or maternity.
  • Race – including colour, nationality and ethnic origin.
  • Religion or belief.
  • Sex.
  • Sexual orientation.

You may have a legal claim if you’ve been harassed or bullied because of one or more of these characteristics.

Even if someone says it was ‘just a joke’ or didn’t mean to offend, what matters is the effect on you.

Harassment can be:

  • Verbal – offensive jokes, slurs, comments or criticism.
  • Physical – unwanted touching, threatening gestures, blocking paths.
  • Visual – inappropriate images, emails or messages.
  • Exclusion – isolating someone from meetings, decisions or social settings.

If the conduct is sexual in nature, such as unwanted touching, comments or propositions, this may amount to sexual harassment.

Frequently asked questions

Yes, raising a formal grievance is often a good first step. It shows you’ve tried to address the issue internally and gives your employer a chance to respond. You’ll need to follow your company’s grievance policy, which usually involves submitting your complaint in writing and attending a meeting to discuss it. If the grievance isn’t handled properly or the outcome isn’t satisfactory, you may be able to take further action. Our workplace harassment solicitors can help you draft your grievance, advise on the process and support you if the situation escalates to a settlement or tribunal.

You don’t need to have formal evidence to raise a concern, but keeping records will strengthen your position. Useful evidence includes emails, messages, screenshots, diary entries, witness accounts, or notes of what was said and when. Even if no one else witnessed the behaviour, your own account is important. If you’re unsure whether you’ve gathered enough, or you’re worried about how to present your case, our workplace harassment lawyers can guide you. We’ll help you put together the clearest possible evidence to support your position and protect your right

Employers are responsible for protecting you from harassment at work - including from third parties like clients, customers or contractors. If your employer knows about the behaviour and doesn’t take steps to stop it, they could be liable. You should report any incidents and keep a record of what happened. If the situation isn’t addressed, legal options may be available. We regularly support employees facing external harassment and can help you raise it appropriately while protecting your position and your well-being at work.

Workplace harassment is any unwanted behaviour related to a protected characteristic - such as age, race, sex, or religion - that creates an intimidating, hostile, degrading, humiliating or offensive environment. It can happen once or repeatedly, and it doesn’t have to be intentional. Harassment can be verbal, physical, written, visual or even non-verbal, like exclusion. If the behaviour has made you feel uncomfortable or undermined your dignity at work, it’s worth getting legal advice. Our workplace harassment lawyers can help you understand whether what you’ve experienced is likely to be considered harassment under the Equality Act.

If you feel you can’t stay in your role because of harassment and your employer has failed to act, you may be able to resign and claim constructive dismissal. This is a serious step and you should get legal advice before making a decision. You’ll need to show that your employer’s failure to protect you breached your contract. Our constructive dismissal solicitors will talk through your situation, the risks, and potential outcomes - including settlement options. If leaving is the right move, we’ll help you do so on your terms and with the support you need.

Yes, you can bring a claim to the employment tribunal if you’ve been harassed at work and your employer has failed to act. You’ll normally need to go through the Acas Early Conciliation process first. tribunal claims have strict time limits - usually three months less one day from the date of the last incident. We’ll help you assess whether you have a claim, guide you through the process and represent you if needed. Our workplace harassment lawyers have significant experience in tribunal claims and are ranked in the Legal 500 for our expertise.

Harassment is defined in law and must relate to a protected characteristic, like sex, disability or race. Bullying, on the other hand, includes repeated behaviour that’s offensive, intimidating, or undermining. Bullying might not be unlawful discrimination, but that doesn’t mean it should be ignored. In some cases, it may breach workplace policies or create grounds for a grievance or constructive dismissal claim. We’ll help you understand your options, whether you’re being bullied, harassed or experiencing both. You don’t have to tolerate mistreatment at work - and we’re here to help you challenge it.
