Your Rights at a Disciplinary Hearing

Being called to a disciplinary hearing is one of the most stressful moments in working life, and many people walk into the room assuming their employer holds all the cards. The reality is different. Your disciplinary hearing rights come from three places: the ACAS Code of Practice on Disciplinary and Grievance Procedures, statute, and decades of tribunal case law on what a fair process looks like. An employer who cuts corners pays for it later - a tribunal can adjust compensation by up to 25% where the Code is unreasonably ignored, and a flawed process is often what turns a dismissal into an unfair one.

What is a disciplinary hearing?

A disciplinary hearing is a formal meeting at which your employer puts allegations of misconduct or poor performance to you, hears your response, and then decides what action, if any, to take. It is not a conviction in waiting. The whole point of the hearing is that no decision has been made yet.

The framework is the ACAS Code of Practice on Disciplinary and Grievance Procedures. The Code is not a contract and breaching it is not automatically unlawful, but tribunals must take it into account, and under section 207A of the Trade Union and Labour Relations (Consolidation) Act 1992 they can raise or lower any compensation award by up to 25% where either side unreasonably failed to follow it. That single rule shapes how sensible employers run the entire process.

What is the difference between the investigation and the hearing?

A fair process has two distinct stages, and it matters which one you are in.

An investigation meeting is fact-finding. Its job is to establish what happened and whether there is a case to answer. No disciplinary decision can be made at it, and there is no statutory right to be accompanied at this stage - although many employers allow it as a matter of policy.

The disciplinary hearing is where the case is formally put to you and an outcome is decided. The ACAS Code expects that, where practicable, different people handle the investigation and the decision. If your employer rolled both into a single meeting, or the investigator also decided the outcome, that is relevant to whether the process was fair.

What are you entitled to before the hearing?

The core right is the right to know the case against you. Under the ACAS Code you can expect:

• Written notification of the allegations, with enough detail to understand what you are accused of and what the possible consequences are - including whether dismissal is on the table
• Copies of the evidence, including witness statements, provided in advance so you can respond to it
• Reasonable notice of the hearing, with enough time to prepare

It is worth asking, in writing, for the investigation report, all witness statements, any CCTV or data being relied on, and the disciplinary policy itself. If material is withheld, record that in writing. And if new allegations or new evidence surface during the hearing itself, you can ask for an adjournment to consider them - a fair employer grants it.

Who can you bring with you?

You have a statutory right to be accompanied under section 10 of the Employment Relations Act 1999. It applies to disciplinary hearings and grievance hearings alike, and your companion can be a trade union representative or a work colleague of your choice.

Your companion can do more than sit there. They can present your case, sum it up, respond on your behalf to views expressed at the hearing, and confer with you throughout. What they cannot do is answer questions put directly to you.

If your chosen companion cannot attend, you can propose a reasonable alternative time within five working days of the original date, and your employer is expected to rearrange. Refusing a properly made request to be accompanied is a breach of a statutory right in its own right, and useful evidence in any later claim.

What if you have been suspended?

Suspension is a precaution, not a punishment, and it is not a presumption of guilt. ACAS guidance is clear that suspension is expected to be considered only where necessary, kept as brief as possible, reviewed regularly, and normally on full pay. Employers are expected to consider alternatives first, such as a temporary change of duties or location.

In practice, a knee-jerk suspension imposed without thought, or one left running for months without review, can itself seriously damage the relationship of trust and confidence between you and your employer. If you are suspended, ask in writing why, for how long, when it will be reviewed, and confirm that you remain on full pay.

What happens at the hearing itself?

A properly run hearing follows a recognisable shape. The employer states the case and goes through the evidence. You respond - to each allegation, with your own evidence and, where arranged in advance, your own witnesses. Both sides can ask questions. The hearing then adjourns before any decision is made; an outcome announced on the spot without any pause suggests the decision was made beforehand.

You can ask for breaks, ask for an adjournment if something new comes up, and take notes throughout. The outcome must be confirmed in writing, with reasons and a right of appeal.

What outcomes can a disciplinary hearing have?

Most disciplinary procedures follow a ladder of warnings. The timeframes below are typical, not statutory - your employer's own policy governs the detail.

Gross misconduct - conduct so serious it destroys the employment relationship, such as theft, violence or serious dishonesty - can justify dismissal without notice even at a first hearing. Outcomes such as demotion or transfer are only available if your contract or the disciplinary policy allows them.

Do you have the right to appeal?

Yes. The ACAS Code expects every disciplinary outcome to carry a right of appeal, heard where practicable by someone more senior who was not previously involved. Put your appeal in writing, state your grounds - new evidence, procedural failings, or an outcome that was simply too harsh - and keep a copy.

Appealing matters even if you have little faith in it. Unreasonably skipping the appeal can cut any later tribunal award by up to 25% under section 207A. But note the trap that catches many people: an appeal does not pause the clock on a tribunal claim. The deadline runs from the dismissal itself.

When does a flawed process matter legally?

If the process ends in dismissal, procedure moves centre stage. In an unfair dismissal claim, the tribunal asks whether the employer acted reasonably - and for conduct dismissals it applies the Burchell test, from British Home Stores v Burchell [1978]: did the employer genuinely believe you were guilty, on reasonable grounds, after a reasonable investigation? The tribunal then asks whether dismissal fell within the band of reasonable responses open to a reasonable employer. A hearing run without notice, without evidence, or without a genuine chance to respond can fail that test even where the underlying allegation had substance.

Ordinary unfair dismissal currently requires 2 years' qualifying service, although the Employment Rights Act 2025 is expected to change that - see the guide to day one unfair dismissal rights for the current status. If the process was applied more harshly to you because of a protected characteristic, discrimination law may also be in play, with no qualifying period at all.

The deadline for an unfair dismissal claim is strict: 3 months less 1 day from the dismissal, with ACAS Early Conciliation started before it expires. See the guide to employment tribunal deadlines for how the timing works.

What to do now

If the hearing is still ahead of you, your priorities are practical: ask for the evidence in writing, arrange your companion, write your chronology, and answer the allegations point by point. If the issue behind the disciplinary is really a problem of your employer's making, you may also want to consider raising it formally - the guide to writing a grievance letter explains how a grievance and a disciplinary can run side by side. And if the process has already ended in dismissal, the deadline is now the most important fact in your case - everything else can come after.

This guide contains legal information, not legal advice. Disciplinary cases turn on their facts, and tribunals look at the process as a whole. If you are unsure how this applies to your situation, you may want to consider speaking to an employment law specialist.
