What happens in a UK employment dispute

Employment disputes are stressful, confusing, and often overwhelming. But the process underneath is more structured than most people realise. The stages are well-established, the path is well-trodden, and thousands of people walk through it every year — many without a solicitor.

Your circumstances are unique. The process isn't. Whether you're dealing with unfair dismissal, discrimination, redundancy, or unpaid wages, you'll follow broadly the same route — you may enter at a different point, move through certain stages faster, or settle before reaching a hearing. But the structure is the same.

This guide walks through the 8 stages of a UK employment dispute from first question to final outcome. Each stage links to a detailed breakdown with tasks, considerations, and tools.

Before you start

Three things matter more than anything else in the early stages of an employment dispute: understanding how the law applies to your situation, deadlines, and evidence. Most tribunal claims must be started within 3 months minus 1 day of the event you're complaining about. Miss that window and your case can be over — regardless of how strong it is.

Evidence means documents: your contract, payslips, emails, letters, meeting notes, text messages. Start gathering these immediately. Don't wait until you're sure you want to make a claim. Evidence disappears — emails get deleted, access gets revoked, memories fade.

Stage 1 of 8

Understanding your issue

Before anything else, you need to understand what actually happened, which employment rights may be relevant, and whether you have grounds for a claim. Most people skip this stage — and pay for it later.

Identify the type of issue: dismissal, discrimination, pay dispute, whistleblowing, redundancy

Check which employment rights apply to your situation

Understand whether you meet eligibility criteria (employment status, length of service)

Calculate your key deadlines — most tribunal claims must be started within 3 months minus 1 day

Gather initial evidence: contract, payslips, correspondence, notes

Typical duration: Days to 2 weeks

Stage 2 of 8

Internal process

Employment tribunals expect you to have tried to resolve things at work before making a formal claim. This usually means raising a grievance. Skipping it can reduce your compensation even if you win.

Raise the issue informally with your manager or HR if appropriate

If unresolved, submit a formal written grievance following your employer's procedure

Attend a grievance hearing — you have the right to be accompanied

If the outcome is unsatisfactory, appeal in writing within the timeframe given

Keep copies of everything: your grievance letter, their response, meeting notes, emails

Typical duration: 2–6 weeks

Full guide: Internal process

Stage 3 of 8

ACAS early conciliation

Before you can submit a tribunal claim, you must contact ACAS. This is a legal requirement, not optional. If you engage with early conciliation, a conciliator will try to broker a resolution between you and your employer. Around 76% of cases that proceed to conciliation settle at this stage.

Notify ACAS online or by phone — this starts the clock (Day A)

ACAS contacts your employer and attempts to facilitate a settlement

The conciliation period lasts up to 6 weeks (extendable in some cases)

If you settle, it's recorded on a COT3 — a legally binding agreement

If you don't settle, ACAS issues an early conciliation certificate — you need this to submit a tribunal claim

Your tribunal deadline is extended by the conciliation period

Typical duration: 1–6 weeks

Stage 4 of 8

Tribunal claim

If ACAS conciliation doesn't resolve things, you submit your claim to the employment tribunal using an ET1 form. Your employer responds with an ET3. This is where the formal legal process begins.

Complete and submit the ET1 form online through the HMCTS portal

Include your ACAS early conciliation certificate number

Set out the facts of your claim clearly — what happened, when, and what you're claiming

Your employer has 28 days to respond with an ET3

The tribunal sends both parties a notice of the claim and next steps

Typical duration: 1–4 weeks to submit; 28 days for response

Full guide: Tribunal claim

Stage 5 of 8

Case preparation

This is the longest stage and often the most important. You gather evidence, build your timeline, prepare witness statements, and assemble your bundle. How well you prepare here largely determines how your hearing goes.

Respond to any case management orders from the tribunal

Disclose relevant documents to the other side (and receive theirs)

Build a chronological timeline of events with supporting evidence

Prepare witness statements — your own and any witnesses supporting your case

Assemble the hearing bundle: an agreed, paginated set of documents both sides will refer to

Consider whether a preliminary hearing is needed to clarify legal issues

Typical duration: 2–6 months

Stage 6 of 8

Tribunal hearing

The hearing is where your case is decided. You present your evidence, the other side presents theirs, and a judge (sometimes with panel members) makes a determination. Most hearings last 1–5 days depending on complexity.

Attend in person or by video (the tribunal will confirm the format)

Present your case: opening statement, witness evidence, cross-examination

The respondent presents their case and you can cross-examine their witnesses

The judge may ask questions throughout

The decision may be given on the day or reserved for a written judgment later

Typical duration: 1–5 days; judgment may take weeks

Full guide: Tribunal hearing

Stage 7 of 8

Settlement

Settlement can happen at any point — before ACAS, during preparation, even at the door of the tribunal. Many employment disputes settle before a full hearing. Understanding your position and what a realistic outcome looks like makes negotiation more effective.

Settlement can be offered or initiated by either side at any stage

Terms are usually financial (compensation) plus practical (reference, announcement)

If agreed through ACAS, it's recorded on a COT3

If agreed privately, it's a settlement agreement — you'll need independent legal advice for it to be binding

Once signed, you waive the right to pursue the claim further

Typical duration: Can happen at any point

Full guide: Settlement

Stage 8 of 8

Appeals and enforcement

If the tribunal makes a decision and one side disagrees, there may be grounds for appeal. If you win but your employer doesn't pay, you may need to take enforcement steps. This stage only applies if the dispute reaches — and concludes — a hearing.

Appeals go to the Employment Appeal Tribunal (EAT) on points of law only

You have 42 days from the date of the written judgment to lodge an appeal

If your employer doesn't pay a tribunal award, you can apply for enforcement through the county court or HMCTS

Penalty charges can be added if the employer fails to pay within the set period

Typical duration: Weeks to months

Full guide: Appeals and enforcement

What most people get wrong

Waiting too long to act

The 3-month deadline is real and strictly enforced. Tribunals have rejected claims that were 88 seconds late. Don't assume you have time to think about it.

Skipping the grievance

Tribunals expect you to have raised the issue internally. Skipping the grievance process can reduce your compensation by up to 25% — even if you win on the substance of your claim.

Poor evidence organisation

10% of cases are struck out due to avoidable procedural errors. A disorganised case with missing documents, unclear timelines, and missed directions doesn't just look bad — it can end your claim before a judge hears it.

Assuming you need a solicitor to start

Around 70% of tribunal claims are brought without legal representation. You may need a solicitor at some point — but understanding your position, calculating your deadlines, and organising your evidence are things you can do yourself, and doing them early makes everything else easier.
