Employment Tribunal Timeline

A plain English, step-by-step guide to what happens when a workplace dispute becomes an Employment Tribunal claim — and roughly how long each stage takes.

Every case is different. The timeline below shows the typical journey, with CaseIntel benchmarks against more than 54,000 real tribunal decisions to help you understand likely outcomes.

The full picture

The Employment Tribunal journey at a glance

Most Employment Tribunal claims follow the same broad path, even though the timing of each stage varies significantly between cases.

  1. Step 01

    Workplace dispute

    A dispute arises — for example dismissal, discrimination, unpaid wages or a breakdown in the working relationship.

    Day 0
  2. Step 02

    ACAS Early Conciliation

    Free, confidential conciliation via ACAS. Often resolves the dispute without a tribunal claim being issued.

    Typically up to 6 weeks
  3. Step 03

    Tribunal claim submitted (ET1)

    Claimant files the ET1 form setting out the claims and key facts within the statutory time limit.

  4. Step 04

    Employer response (ET3)

    Respondent files a defence — usually within 28 days of being served the claim.

  5. Step 05

    Case management

    The tribunal sets directions: issues, disclosure deadlines, witness statement exchange and a hearing window.

  6. Step 06

    Disclosure of documents

    Both sides exchange relevant documents — typically emails, contracts, policies and investigation notes.

  7. Step 07

    Witness statements

    Each party prepares and exchanges written statements from the people who will give evidence.

  8. Step 08

    Final hearing

    Witnesses give evidence and are cross-examined; advocates make legal submissions; the tribunal hears the case.

    Often 1–10 days
  9. Step 09

    Judgment

    The tribunal delivers its decision — either orally at the end or reserved in writing.

  10. Step 10

    Compensation (where applicable)

    If the claim succeeds, the tribunal sets a remedy. Compensation is the most common outcome.

Stage 1

ACAS Early Conciliation

Before most Employment Tribunal claims can be issued, the claimant must first notify ACAS (the Advisory, Conciliation and Arbitration Service) and go through Early Conciliation. This is a free service designed to help parties resolve disputes without litigation.

An ACAS conciliator speaks to both sides and explores whether a settlement is possible. If it is, the matter ends with an agreement. If it isn't, ACAS issues an Early Conciliation Certificate, which the claimant needs in order to submit a tribunal claim.

Settlement

Parties agree terms, usually documented in a COT3 agreement via ACAS.

Certificate issued

No agreement reached — claimant receives a certificate and can proceed to tribunal.

Time limits

Strict deadlines apply. Early Conciliation pauses the clock; missing a deadline can end the claim.

Why settlement matters here
A meaningful number of disputes resolve at this stage. See our Settlement Agreements Explained guide for how offers are typically structured.
Stage 2

Making a Tribunal Claim

If Early Conciliation doesn't resolve the dispute, the claimant submits an ET1 claim form to the Employment Tribunal. This sets out the claims being brought (for example unfair dismissal, discrimination, unpaid wages) and the key facts.

The employer (now the respondent) is sent the claim and given a deadline — usually 28 days — to file an ET3 response setting out their defence. After both forms are in, the tribunal carries out initial case management to decide how the case will be run.

ET1 — the claim

Claimant sets out the claims and the facts, and pays no issue fee (currently).

ET3 — the response

Respondent files a defence within the deadline, accepting or contesting each claim.

Case management

The tribunal sets directions: disclosure deadlines, witness statements and a hearing window.

Stage 3

Preparing for the Hearing

Most of the work in a tribunal claim happens before the hearing itself. The parties exchange documents, prepare witness evidence and put together a bundle the tribunal will use on the day.

Disclosure

Both sides exchange relevant documents — emails, contracts, policies, meeting notes.

Witness statements

Each witness sets out their evidence in writing, usually exchanged on the same date.

The hearing bundle

A paginated bundle of documents and statements is prepared and sent to the tribunal.

Negotiation

Settlement discussions often continue throughout this period, sometimes right up to the hearing.

Preparation drives outcomes
Tribunal outcomes are heavily influenced by the quality of evidence — documents, chronologies and witness preparation — not just the headline facts of the dispute.
Stage 4

The Final Hearing

The final hearing is the formal trial of the claim. Depending on complexity, it may take anywhere from a single day to several weeks. Straightforward unfair dismissal claims are typically heard by a single Employment Judge; discrimination claims often sit before a panel including non-legal members.

Witnesses confirm their statements, are cross-examined and answer questions from the tribunal. The advocates make submissions on the law and the evidence. The tribunal then either gives an oral decision at the end or reserves judgment in writing.

Who attends

Claimant, respondent representatives, witnesses, and (usually) legal representatives.

How decisions are made

The tribunal weighs the evidence against the legal tests for each claim brought.

Liability vs remedy

Some cases split into a liability hearing and a separate remedy hearing on compensation.

Stage 5

Judgment and Compensation

If the claim succeeds, the tribunal decides on a remedy. For most unfair dismissal claims that means compensation; in some cases the tribunal can order reinstatement or re-engagement. Discrimination claims can also include injury to feelings.

If the claim fails, no compensation is awarded. Costs orders in the Employment Tribunal are relatively rare compared to other courts but are possible in limited circumstances.

FAQ

Frequently Asked Questions

How long does an Employment Tribunal usually take?+

Timelines vary widely. A straightforward unfair dismissal claim might reach a final hearing within around six to twelve months in some regions, while complex discrimination claims often take significantly longer.

Regional backlogs, the number of issues in dispute and the length of the hearing all affect how quickly a case is listed.

Do most claims reach a final hearing?+

No. A significant share of Employment Tribunal claims are resolved before a final hearing — through ACAS Early Conciliation, judicial mediation or direct negotiation between the parties.

That's why benchmarking likely outcomes early can be valuable, even if you don't intend to go all the way to a hearing.

Can I settle during the tribunal process?+

Yes. Settlement discussions can happen at any point — before issuing a claim, after it has been issued, during preparation, and even on the morning of the hearing.

Many cases are documented in a COT3 (via ACAS) or a settlement agreement.

What happens if I lose my tribunal claim?+

If a claim is unsuccessful, no compensation is awarded. Costs orders in the Employment Tribunal are relatively uncommon compared to other courts, but are possible in limited circumstances — for example, where a party has behaved unreasonably.

There may also be limited rights of appeal on points of law.

Do I need a solicitor for an Employment Tribunal?+

There is no requirement to be legally represented. Many claimants represent themselves, particularly in straightforward unfair dismissal cases.

More complex or higher-value claims — particularly discrimination or whistleblowing — often benefit from specialist employment law representation.

Can I bring a claim while still employed?+

Yes. Some claims — for example discrimination or unlawful deductions — can be brought during employment as well as after it ends.

Strict time limits still apply from the date of the act being complained about.

What is the time limit for bringing a claim?+

Most Employment Tribunal claims must be started within three months less one day of the act complained of, subject to extension via ACAS Early Conciliation.

Different rules apply to certain claims, and the clock is unforgiving — missing the deadline usually ends the claim.
