What to do when someone discloses harassment

When someone tells you they have been harassed, how you respond in that first moment matters enormously. If you manage people, or you are simply the person a colleague trusted enough to tell, this can land on you with no warning. The goal is simple: listen, believe them, and support them. It is not to investigate, judge, or fix it on the spot. Get that first response right and you help the person feel safe and heard. Get it wrong and you can make things worse, and increasingly create fresh legal problems for your organisation. Here is how to handle a disclosure well.

Why the first response matters

For most people, telling someone they have been harassed takes real courage, and they are watching closely how it lands. A calm, believing response can be the difference between someone feeling supported and someone shutting down or leaving. It also matters legally. Tribunals have found that mishandling a complaint can itself amount to harassment or victimisation, a fresh claim on top of the original one. So the moment of disclosure is not only a human responsibility, it is part of meeting your legal duty.

Two things matter most: being believed, and keeping control

If you remember nothing else, remember these two.

Being believed. For many people, the fear of not being believed, or of being made to justify themselves, is exactly why they never speak up. Government-cited evidence suggests around half of those who experience harassment at work do not report it. So when someone does, believing them is the most important thing you can do. Being believed does not mean pre-judging any investigation. It means not treating the person as suspect simply for coming forward.

Autonomy. Harassment takes away a person's sense of control, so a good response gives it back. Ask what they want to happen rather than deciding for them, explain their options, and let them set the pace as far as you can. Be honest if there is something you are genuinely required to act on, but do not steamroll them into a process they are not ready for. Their sense of control is part of how they recover.

In the moment: what to do

Keep it simple and human:

• Listen, and let them talk without interrupting or questioning their account.
• Take it seriously and thank them for telling you. That alone matters more than people realise.
• Stay calm and non-judgemental, whatever you are feeling.
• Ask what they need right now, rather than deciding for them.
• Be honest about what happens next. Explain, gently, that you may need to pass this on so it can be handled properly.
• Keep it as private as you can, and share it only with those who genuinely need to know.

What not to do

• Do not minimise it, explain it away, or suggest they may have misread the situation.
• Do not promise to keep it completely secret. You may not be able to, and a broken promise destroys trust. Be honest from the start.
• Do not try to investigate it yourself in the moment, or confront the person they have named.
• Do not tell them to sort it out themselves.
• Do not sit on it. Delay looks like indifference and can make things worse.

Afterwards: the next steps

Once the conversation is over, write down what was said as soon as you can, factually and in their words, not your interpretation. Follow your organisation's policy for what happens next, and act without unreasonable delay. Throughout, keep supporting the person, keep them informed, and make sure they are protected from any backlash for having spoken up. How someone is treated after they report is just as important as the response in the room.

The legal side, briefly

Two things are worth knowing. First, as above, mishandling a disclosure can create a fresh claim for harassment or victimisation, separate from the original incident. Second, since 6 April 2026, a disclosure about sexual harassment can count as a "qualifying disclosure" under whistleblowing law. It is not automatic: the person still needs a reasonable belief in what they are reporting, and it generally needs to be in the public interest. But where those tests are met, someone who speaks up is protected from being treated badly or dismissed for doing so, and a confidentiality agreement cannot lawfully be used to override that protection. Wider limits on using NDAs in harassment cases are also expected to follow. So how you respond to a disclosure now carries real legal weight, and is part of the duty to prevent harassment.

Where practice comes in

Here is the hard truth: almost no one is ever given the chance to practise this before it happens for real. Managers are handed a policy and left to hope they get it right in the moment that matters most. That is exactly what Scenari is built for: a safe space to practise responding to a disclosure, with trauma-informed coaching, so that when someone real comes to them, they already know how to respond. And if you need expert support with a live situation, our sister organisation OneSource HR, a trauma-informed specialist in sexual misconduct at work, can help.

Common questions

Should I keep a disclosure confidential? Be honest rather than promising total secrecy. Keep it as private as possible and share only with those who need to know, but you may have a duty to act on what you have been told, so do not promise to keep it entirely to yourself.

Should I investigate when someone discloses to me? Not in that moment. Your job when someone discloses is to listen and support. Any investigation should follow your organisation's proper process, carried out fairly and without unreasonable delay.

What should I write down? A factual record of what the person told you, in their own words where possible, made as soon as possible after the conversation. Avoid adding your own opinions or conclusions.

Can we use an NDA to keep it quiet? Not to silence a protected disclosure. Since 6 April 2026, a report of sexual harassment can be a qualifying disclosure under whistleblowing law, and where it is, a confidentiality agreement cannot lawfully be used to stop the person speaking up or punish them for it. Wider limits on using NDAs in harassment cases are expected to follow.
