What is a disciplinary hearing?
A disciplinary hearing is a formal meeting where your employer presents concerns about your conduct, performance, or absence and you get the chance to respond. It is part of a wider disciplinary and grievance process that all employers should follow.
It is not an informal chat with your manager. A disciplinary hearing is a formal step that can result in written warnings, final warnings, or dismissal.
What triggers a disciplinary?
Common reasons include:
- Alleged misconduct (lateness, policy breaches, inappropriate behaviour)
- Performance concerns (not meeting targets, capability issues)
- Absence-related issues (patterns of sickness absence)
- Gross misconduct allegations (theft, violence, fraud, serious safety breaches)
Before any hearing takes place, your employer should have carried out a reasonable investigation to establish the facts.
Your legal rights
These rights are backed by employment law and the ACAS Code of Practice:
1. The right to know the case against you
Your employer must give you written notification of the specific allegations, copies of the evidence they plan to rely on, and enough time to prepare — at minimum 48 hours, though best practice is five working days.
An employer who springs a hearing without prior notice or refuses to share the evidence has already undermined the process.
2. The right to be accompanied
Under Section 10 of the Employment Relations Act 1999, you can bring a companion to any formal disciplinary hearing. This must be a trade union representative (from any union, whether or not it is recognised by your employer) or a fellow worker.
Your companion is not there for moral support alone — they can present your case, ask questions, and confer with you privately during the hearing. Read our full guide on your right to be accompanied.
3. The right to respond
You must be given a genuine opportunity to hear the allegation, ask questions, present your own evidence, call witnesses, and explain your side before any decision is made.
4. The right to appeal
Whatever the outcome, you have the right to appeal. The appeal should be heard by someone not involved in the original decision.
Before the hearing: how to prepare
Preparation is the difference between a fair outcome and a bad one.
Read the investigation pack against what should have happened at the investigation meeting, because gaps there weaken the case against you.
Step 1: read the invitation letter
Check the exact allegation. The wording matters — a vague phrase like “poor conduct” is not good enough. Check what evidence has been provided, when and where the hearing is, who will be conducting it, and whether your right to be accompanied is mentioned. If anything is missing, write back and ask for it. You are entitled to enough information to prepare properly.
Step 2: gather the evidence
Request any evidence your employer holds that is relevant — not only the evidence they plan to use against you. Under data protection law (UK GDPR), you can make a Subject Access Request for any personal data your employer holds about you.
Gather your own evidence too: emails, messages, your employment contract, relevant policies, records of previous performance reviews (especially positive ones), and details of any witness who can support your account.
Step 3: prepare a written statement
Write your response to each allegation, point by point. Keep it factual. Structure it as: the allegation, your response with reference to evidence, and any mitigating circumstances. Having this written down means you will not forget key points under pressure. You can give a copy to the panel at the start of the hearing.
Step 4: arrange your companion
If you are a member of a trade union, contact them immediately — they can provide a trained representative. A trained representative knows what questions to ask, what procedural failures to challenge, and how to present your case. This is one of the biggest advantages of union membership.
Step 5: know the possible outcomes
Understand the range of sanctions your employer can impose (see possible outcomes in our full guide). If you know the range, you can prepare arguments about proportionality — why a lesser sanction fits the facts.
Step 6: plan practically
Confirm the date works for you and your companion. If it does not, you can request a postponement — your employer must reschedule once if your companion is unavailable. Plan your route and arrive fifteen minutes early. Bring copies of all documents and evidence. Bring a notepad and pen.
On the day: what to expect
A typical disciplinary hearing follows this format:
- Introduction — the chair explains the process and confirms who is present
- Management case — your employer presents the allegation and goes through the evidence
- Your questions — you or your companion can challenge any points
- Your response — you present your case, including your written statement, evidence, and any witnesses
- Management questions — your employer may ask follow-up questions
- Summing up — both sides summarise their position
- Adjournment — the panel adjourns to consider the evidence and reach a decision
During the hearing:
- Stay calm and professional, even if the process feels unfair. Your conduct will be noted.
- Ask for breaks to confer with your companion privately — this is your right.
- Do not let yourself be rushed. If you need time to consider a question, say so.
- If new evidence is introduced that you have not seen before, ask for an adjournment to review it. You should not be ambushed.
- Take notes, or have your companion take them.
After the hearing: outcomes and next steps
Your employer should confirm the decision in writing within a few working days. The letter should include the decision and reasons, any sanction, how long a warning will remain on your record, and your right to appeal with the deadline and process.
If the outcome goes against you, how to appeal a disciplinary decision sets out the grounds and the deadline.
If you receive a warning
Check whether the sanction is proportionate. A first offence should not normally result in a final written warning or dismissal unless it involves gross misconduct. If the sanction is out of proportion, appeal.
If you are dismissed
You may have grounds for an unfair dismissal claim if your employer did not follow a fair procedure, the decision was out of proportion, the investigation was inadequate, or you were treated differently from others in similar situations.
You normally have three months minus one day from the date of dismissal to begin Early Conciliation with ACAS. This is a strict time limit.
Common employer mistakes
Watch for these — they strengthen your position on appeal or at tribunal:
- No proper investigation before the hearing
- Evidence not shared in advance
- Not enough time given to prepare
- Right to be accompanied refused
- Decision reached before the hearing (pre-determined outcome)
- New allegations introduced that were not in the invitation letter
- No appeal offered, or the same person hearing the appeal
- Inconsistent treatment — different employees treated differently for similar issues
If your employer makes any of these mistakes, raise them. If they are not corrected, record them for your appeal.
If the hearing ends in a warning, our guide explains how long a written warning stays on your file.
Where your employer questions your performance rather than your conduct, it should start with a performance improvement plan.
If you are facing a hearing without a union, our guide to whether joining a trade union is worth it sets the cost against the risk.
FAQs
Can my employer hold a disciplinary hearing without me?
Yes, but only as a last resort. Your employer must make reasonable efforts to rearrange and accommodate you first — especially if you are off sick. Going ahead without trying to accommodate you could make the process, and any resulting dismissal, unfair.
Can I bring a solicitor to a disciplinary hearing?
There is no legal right to bring a solicitor. The statutory right covers trade union representatives and fellow workers only. Your employer may agree voluntarily, and some employer policies extend the right. In practice, a trade union representative with disciplinary experience is often as effective as a solicitor — and costs the member nothing.
What if I am suspended before the hearing?
Suspension should be on full pay and treated as a neutral act — not a punishment. Your employer should only suspend when genuinely necessary, such as protecting an investigation or ensuring safety. Suspension without pay, or for an unreasonably long period without progressing the investigation, should be challenged in writing.
Can I resign before a disciplinary hearing?
You can resign at any time, but it may not serve your interests. Resigning does not erase the underlying issue and may weaken your position if you later want to make a claim. If you resign because your employer’s conduct has left you no reasonable choice, you may have a claim for constructive dismissal. Speak to a union representative before making that decision — there may be better options.
How long should I have to prepare for a disciplinary hearing?
Good practice is at least five working days. The ACAS Code of Practice requires “reasonable time” but does not specify an exact minimum. If your employer gives you less than 48 hours, push back in writing. An employer who rushes the process risks the hearing being found procedurally unfair.
