Employment tribunals in dismissal disputes: how they work, what claims can be brought, legal time limits, ACAS early conciliation, and potential remedies such as compensation, reinstatement, and unfair dismissal rulings in England and Wales.

An employment tribunal is a specialist judicial body that resolves disputes between employees and employers in England and Wales. In dismissal disputes, it is the primary forum for determining whether a termination of employment was lawful, fair, and procedurally correct.
Tribunals operate independently of government departments and courts, and are designed to provide a less formal setting than the civil courts while still applying statutory employment law. They commonly hear claims relating to unfair dismissal, wrongful dismissal, discrimination, and breach of contract.
In dismissal cases, the tribunal assesses whether the employer had a lawful reason to dismiss an employee and whether a fair process was followed before ending employment.
Legal Basis for Employment Tribunals
Employment tribunals derive their authority from statutes including the Employment Tribunals Act 1996 and the Employment Rights Act 1996. They have jurisdiction over a wide range of employment-related claims, including dismissal disputes.
In most dismissal cases, the tribunal considers:
- Whether the dismissal falls within one of the legally recognised fair reasons (conduct, capability, redundancy, statutory restriction, or “some other substantial reason”)
- Whether a fair procedure was followed in reaching the decision
- Whether the employer acted reasonably in the circumstances
For unfair dismissal claims, the tribunal applies the “range of reasonable responses” test, assessing whether a reasonable employer could have dismissed the employee in the same circumstances.
Types of Dismissal Claims Heard by Tribunals
Employment tribunals deal with several categories of dismissal-related claims.
Unfair Dismissal
A claim for unfair dismissal is based on statutory rights under the Employment Rights Act 1996. It examines whether the employer had a fair reason and followed a fair process.
Most employees require at least two years of continuous service, although some dismissals are automatically unfair (for example, whistleblowing or pregnancy-related dismissal), where no qualifying period applies.
Wrongful Dismissal
Wrongful dismissal is a contractual claim, usually focusing on whether the employer failed to give proper notice or breached the employment contract. It does not assess fairness, only legal entitlement under contract terms.
Constructive Dismissal
This arises where an employee resigns due to the employer's conduct, which is treated as a dismissal in law if the breach of contract is sufficiently serious.
The Role of ACAS Before a Tribunal Claim
Before most dismissal claims can proceed, the claimant must notify the Advisory, Conciliation and Arbitration Service (ACAS) and engage in early conciliation. This is a mandatory preliminary step in most cases.
Advisory, Conciliation and Arbitration Service facilitates settlement discussions between the parties before formal proceedings begin. If resolution is not achieved, ACAS issues an early conciliation certificate, which is required to start a tribunal claim.
Early conciliation also pauses the limitation period, which is generally three months less one day from the date of dismissal for most claims.
Time Limits for Bringing a Dismissal Claim
Strict time limits apply to employment tribunal claims.
In most dismissal disputes:
- The claim must be lodged within 3 months less one day from the effective date of termination
- The limitation period is paused during ACAS early conciliation
- A claim submitted outside the time limit may be rejected unless an extension is granted in limited circumstances
Missing the deadline is one of the most common reasons claims cannot proceed.
How an Employment Tribunal Process Works in Dismissal Cases
1. Early Conciliation
The process begins with ACAS early conciliation. If settlement is not reached, the claimant receives a certificate.
2. Submitting the ET1 Claim Form
The claimant submits an ET1 form setting out:
- Employment details
- Grounds for the claim
- Facts surrounding the dismissal
- Compensation or remedy sought
3. Employer Response (ET3)
The employer files a response (ET3), setting out their defence, including reasons for dismissal and procedural steps followed.
4. Case Management
A tribunal judge may hold preliminary hearings to define issues, set deadlines, and manage evidence.
5. Final Hearing
Both parties present evidence, witness statements, and legal arguments. The tribunal then issues a binding decision.
How Tribunals Assess Dismissal Disputes
In unfair dismissal cases, tribunals focus on two key questions:
- Did the employer have a potentially fair reason for dismissal?
- Did the employer act reasonably in treating that reason as sufficient for dismissal?
The tribunal will also consider procedural fairness, including whether:
- A proper investigation was conducted
- The employee was informed of allegations
- A disciplinary hearing took place
- The employee had the opportunity to appeal
Even if a dismissal is substantively justified, failure to follow a fair process can still result in a finding of unfair dismissal.
Remedies Available in Tribunal Dismissal Claims
If a claim succeeds, the tribunal may award one or more remedies.
Compensation
Compensation typically includes:
- Basic award (similar to statutory redundancy payment calculation)
- Compensatory award for financial losses caused by dismissal
There are statutory limits on compensatory awards in ordinary unfair dismissal cases, subject to annual adjustment.
Reinstatement or Re-engagement
In some cases, the tribunal may order:
- Reinstatement (return to the same job)
- Re-engagement (new job with the same employer or associated employer)
These remedies are less common in practice.
Common Issues in Dismissal Tribunal Cases
Procedural Errors
Employers often lose cases due to flawed disciplinary procedures rather than lack of substantive justification.
Documentation and Evidence
Tribunals rely heavily on written evidence, including:
- Emails and internal communications
- Disciplinary records
- Investigation reports
- Witness statements
Burden of Proof
In unfair dismissal claims, the employer must show the reason for dismissal and that it was reasonable.
Risks and Considerations for Claimants
Employment tribunal proceedings involve several practical considerations:
- Strict time limits must be observed
- Evidence must be carefully organised and consistent
- Costs are generally not awarded, but in rare cases may be imposed for unreasonable conduct
- Proceedings can take several months to over a year depending on complexity and backlog
Key Takeaways
An employment tribunal is the primary legal forum for resolving dismissal disputes in England and Wales. It determines whether a dismissal was lawful, fair, and properly handled in accordance with employment law.
Before reaching tribunal, most claimants must engage with ACAS early conciliation. Claims are subject to strict time limits, and cases are decided based on statutory law, procedural fairness, and evidence presented by both parties.
Tribunals can award compensation and, in limited cases, reinstatement or re-engagement, making them a key mechanism for resolving employment dismissal disputes.
