How to Appeal a Decision Made by Your Employer

When an employer makes a decision that affects your employment - such as a disciplinary sanction, grievance outcome, performance review decision, or dismissal - you usually have a right to ask for that decision to be reviewed through an internal appeal process. An appeal gives you the opportunity to explain why the outcome was incorrect, unfair, procedurally flawed, or based on incomplete information. This article explains what an appeal is, how to prepare and submit an appeal, what to expect at an appeal hearing, and what options are available if the internal appeal does not resolve the issue. The guidance below reflects current workplace standards and statutory expectations in England and Wales, drawing on practices recommended by authoritative sources.

What Does an Appeal Mean in Employment Context

An appeal is a formal request to an employer to reconsider a decision that has been made about your employment. This can include decisions arising from:

• a disciplinary process (for example, a warning or demotion);
• a grievance (a complaint about treatment at work);
• a dismissal;
• other formal decisions affecting your role or terms.

Your employer should give you an opportunity to appeal - this is part of basic procedural fairness and is reflected in workplace policies and the Acas Code of Practice on disciplinary and grievance procedures.

When You Can Appeal a Decision

You can usually appeal where you believe the decision:

• was incorrect or unfair in substance;
• followed an unfair or incomplete procedure;
• overlooked key evidence or new relevant information;
• imposed a disproportionate outcome.

The right to appeal typically arises from your employer's disciplinary or grievance policy. Some employers also provide appeal rights for other formal decisions, such as performance evaluation outcomes. If your contract or policy does not specify appeal rights, you should still ask for an internal review in writing, explaining your reasons.

Step‑by‑Step Guide to the Appeal Process

1. Review Your Employer's Policy

Check your employment contract and your employer's disciplinary or grievance procedures. These should set out:

• who to address your appeal to;
• any time limits for submitting an appeal;
• the format and content required (for example, whether you need to use a form).

If no timescale is specified, you should submit your appeal as soon as possible, with five working days being a commonly recommended timeframe.

2. Submit Your Appeal in Writing

Put your appeal in writing to create a clear record. Your appeal letter or email should:

• state which decision you are appealing;
• explain why you believe it was wrong, unfair, or procedurally flawed;
• include any new evidence or points that were not considered;
• outline what outcome you are seeking (for example, reconsideration or overturning of the decision).

Clear, reasoned arguments help your employer understand your grounds for appeal and may improve the chance of a favourable outcome.

3. Prepare for the Appeal Hearing

Your employer should invite you to a hearing to discuss your appeal. They should provide written notice of:

• the date, time and venue of the hearing; and
• your right to be accompanied by a companion (such as a work colleague or trade union representative).

At the hearing you can:

• outline why you think the original decision was unjust;
• point to unfair procedures or missing evidence;
• present new information where appropriate;
• respond to any questions or points from management.

The appeal panel should, where possible, be conducted by a person not previously involved in the case to ensure impartiality.

4. Employer Decision After the Appeal

After the hearing, your employer should give you a written conclusion of the appeal. This will normally state:

• whether they have changed, upheld, or partially varied the original decision;
• the reasons for the outcome; and
• whether this represents the final internal decision in your organisation.

Employers are expected to communicate the outcome without unreasonable delay following the appeal meeting.

Appealing a Dismissal

If the original decision was a dismissal, your appeal may ask for that dismissal to be reconsidered. A successful appeal against dismissal usually results in reinstatement, sometimes referred to as a “vanishing dismissal” because the original decision is treated as if it had never taken effect. Your employer should also correct any records or pay adjustments to reflect continuous employment where applicable.

If you do not want reinstatement, you should make this clear to your employer before they issue the final appeal outcome.

What Happens If the Appeal Is Unsuccessful

If your appeal is not upheld and you still believe the decision was unfair or procedurally flawed, several options may be available:

Further Internal Review

Some employers' procedures allow for multiple levels of appeal (for instance, first to a line manager and then to senior management or an external reviewer). Check your policy.

Grievance Route

If the appeal relates to a grievance matter, you may consider raising a formal grievance if one has not already been pursued.

Employment Tribunal Claims

If the dispute involves broader statutory rights - such as unfair dismissal or discrimination - you may consider bringing a claim to an Employment Tribunal. Usually, you are required to go through Acas Early Conciliation before submitting a tribunal claim. Time limits apply (for example, normally three months minus one day for an unfair dismissal claim), so seek guidance on deadlines early.

An unsuccessful internal appeal does not prevent you from taking a statutory claim to a tribunal, but failing to engage in appeal procedures when appropriate can be considered in tribunal proceedings and may affect remedies.

Practical Considerations and Best Practices

Keep written records of all communications, decisions and meeting notes throughout the appeal process. These can strengthen your position both internally and, if necessary, before an Employment Tribunal.

Be clear and specific in your appeal about why you think the initial outcome was incorrect or unfair. Simply stating that a decision was “unfair” without explanation may not be sufficient.

If you are a member of a trade union, seek advice and representation from your union early in the process. Union representatives can offer support, accompany you to appeal hearings, and help articulate legal principles relevant to your case.

Common Questions

Do I have a statutory right to appeal every decision my employer makes?
Not every decision triggers a statutory right of appeal. However, for formal disciplinary and grievance decisions, your employer is expected to provide an appeal process under the Acas Code and common workplace practice.

Can my employer refuse to listen to my appeal?
Employers should follow their own procedures and recognised fair practice. Ignoring an appeal where one is provided in policy or expected as a reasonable step can be viewed unfavourably in subsequent tribunal proceedings.

Can I be accompanied at an appeal hearing?
Yes. If the appeal relates to disciplinary or grievance decisions, you have a right to be accompanied by a colleague or trade union representative at appeal hearings.

Key Takeaways

Appealing an employer's decision is a structured process that allows you to seek reconsideration of disciplinary outcomes, grievance results, dismissals or other formal decisions. It normally involves submitting a written appeal, preparing for and attending a hearing, and receiving a written conclusion. Employers should handle appeals impartially and without unreasonable delay, and you have the right to be accompanied at appeal hearings. If internal routes do not resolve the issue, further steps such as additional internal reviews, grievance channels, or Employment Tribunal claims may be available. Timely engagement with appeal procedures and keeping clear written records are core to protecting your workplace rights.
