How to Appeal a Disciplinary or Grievance Outcome in Scotland (2026)

Receiving a disciplinary or grievance outcome you believe is wrong is not the end of the process — it is the beginning of the next stage. The right of appeal is one of the core requirements of the ACAS Code of Practice on Disciplinary and Grievance Procedures, and using it effectively is one of the most important steps you can take to protect your position.

Many employees treat the appeal as a formality — something to go through before accepting that the outcome is final. That is a mistake. A well-prepared appeal gives your employer a formal opportunity to correct a flawed decision, creates a further written record of the procedural and evidential failures in the original process, and — critically — is a step that employment tribunals expect employees to have taken. Failing to appeal when the opportunity existed can reduce any subsequent compensation award by up to 25 percent.

This article explains how to appeal a disciplinary or grievance outcome in Scotland, what grounds are available to you, how to structure your appeal, what happens at the hearing, and when to think about what comes next.

When to Appeal — and How Quickly

Most employers set a short deadline for internal appeals — commonly five working days from the date you receive the written outcome. This deadline is set by your employer's own disciplinary or grievance procedure. Check it carefully and do not miss it.

If your employer's procedure does not specify a deadline, the ACAS Code expects appeals to be dealt with without unnecessary delay. In practice this means you should submit your appeal promptly — within five working days as a general guide — even where the policy is silent on timing.

You should appeal if any of the following apply:

the sanction imposed — warning, demotion, or dismissal — is disproportionate to the concern
the grievance outcome fails to address the concerns you raised or gives inadequate reasons
the process was procedurally unfair — the investigation was one-sided, you were denied accompaniment, the same person investigated and decided, or you were not given evidence in advance
evidence that supports your position was not considered or was misrepresented
you have new evidence that was not available at the time of the original hearing
the decision departs from how comparable situations have been handled with other employees
the outcome was not within the range of reasonable responses to the facts

If you are unsure whether you have grounds to appeal, the answer in almost every case is: appeal anyway and set out your concerns as clearly as you can. An appeal that is considered and rejected is better for your position than no appeal at all.

Why the Appeal Matters Beyond the Internal Process

Before setting out how to write an appeal, it is worth being clear about why this stage matters so much — not just internally, but in terms of what comes next.

The ACAS Code requires it. An employer who fails to offer a right of appeal has departed from the Code. An employee who fails to use it when it is available may have any tribunal compensation reduced by up to 25 percent.

It creates a formal record. Every concern you raise in writing at the appeal stage becomes part of the formal record. If the matter proceeds to an employment tribunal, that record is before the tribunal. Procedural failures raised at appeal carry more weight than failures raised for the first time in tribunal proceedings.

It is a genuine opportunity for the decision to change. Appeals are not always unsuccessful. A well-prepared appeal — particularly one that clearly identifies specific procedural failures and refers to your employer's own policy — can and does result in outcomes being overturned or sanctions being reduced.

It tests the independence of the process. If the appeal is heard by someone genuinely independent of the original decision and the outcome is reconsidered properly, that matters. If it is not — if the appeal is clearly a rubber-stamp exercise — that itself is relevant to whether the overall process was fair.

Grounds for Appeal — What You Can Rely On

There are four main categories of appeal ground, and the strongest appeals typically rely on more than one.

Procedural failures

This is the most common and often the most powerful ground. Procedural failures include:

the investigation was inadequate — relevant witnesses were not spoken to, relevant evidence was not considered, or the same person investigated and decided the outcome
you were not given the documents or evidence before the hearing
you were not given sufficient notice of the hearing
you were denied your right to be accompanied
the allegations at the hearing differed from those in the invitation letter
the employer failed to follow a specific step required by their own disciplinary or grievance procedure

Where your employer's own procedure required a specific step and that step was not followed, this is a particularly strong ground — because you are not just saying the employer fell short of a general standard, you are saying they departed from their own stated commitment.

Evidential failures

Where the decision was based on evidence that was incomplete, inaccurate, or presented one-sidedly. This includes:

witness accounts that were accepted without being tested
evidence you provided that was not considered or addressed
documents that were not disclosed before the hearing
the decision-maker drawing conclusions not supported by the evidence

Disproportionality

Where the sanction imposed was too severe given the circumstances, the employee's length of service, their previous record, or the way comparable situations have been handled. In dismissal cases in particular, if the outcome was not within the range of reasonable responses open to the employer, disproportionality is a strong ground.

New evidence

Evidence that was not available at the time of the original hearing can be introduced at appeal. If new witnesses have come forward, new documents have come to light, or circumstances have changed in a way that is relevant to the concern, the appeal is the appropriate place to raise this.

How to Structure Your Appeal

Your appeal should be submitted in writing — by email is standard — and should be clear, specific, and factual. You do not need legal language. You need precision.

A well-structured appeal covers the following:

1. State that you are appealing and identify the decision

I am writing to formally appeal the outcome of my disciplinary hearing / grievance, as communicated to me in writing on [date].

2. Set out each ground of appeal clearly

Number your grounds. For each one, state specifically what went wrong, refer to the relevant part of the process, and where possible refer to the relevant section of your employer's own policy or the ACAS Code.

Ground 1 — Procedural failure: The investigation was conducted by [name], who also chaired the disciplinary hearing. Your disciplinary procedure at section [X] requires these roles to be conducted by different individuals. This was not followed.

Ground 2 — Evidential failure: The outcome letter states that [X]. This is factually incorrect. [Explain why, and refer to any document or account that contradicts it.]

Ground 3 — Disproportionality: Given my [X years] of service, my previously clean disciplinary record, and the circumstances of the incident, a final written warning / dismissal is disproportionate. A first written warning would have been a more reasonable response.

3. State the outcome you are seeking

Be specific. Are you asking for the dismissal to be overturned? For the warning to be reduced? For the grievance to be upheld? Say clearly what you want the appeal to achieve.

4. Request a hearing date and confirm accompaniment

I would be grateful if you could confirm the date of the appeal hearing and note that I intend to exercise my right to be accompanied.

Example Appeal Opening

Dear [Name / HR],

I am writing to formally appeal the outcome of my disciplinary hearing, as communicated to me in your letter dated [date].

I am appealing on the following grounds, which I set out below. In summary, I believe the process was procedurally flawed, that relevant evidence was not considered, and that the sanction imposed is disproportionate to the circumstances.

[Set out grounds as numbered points]

I am seeking [dismissal overturned / warning reduced to / grievance upheld in respect of X].

I would be grateful if you could confirm the date and arrangements for the appeal hearing and note that I intend to bring a companion.

Yours sincerely, [Your name]

What Happens After You Submit Your Appeal

On receiving your appeal, your employer should arrange an appeal hearing without unnecessary delay. The invitation should be in writing and should include:

the date, time, and location or method of the hearing
confirmation of your right to be accompanied
details of who will be hearing the appeal

The person hearing the appeal should not have been involved in the original decision. This is a requirement of both the ACAS Code and most employers' own procedures. If the same person who issued the original outcome is also hearing the appeal, that is a procedural failure — raise it in writing before the hearing.

What Happens at the Appeal Hearing

An appeal hearing follows a similar structure to the original hearing. You should be given the opportunity to present your grounds of appeal, refer to any evidence, and make the case for the outcome you are seeking.

At the hearing:

go through each ground of appeal clearly and specifically
refer to the relevant part of your employer's procedure or the ACAS Code where applicable
refer to any evidence that contradicts the original decision
put any new evidence formally on the record
ask questions about how the investigation was conducted and how the decision was reached
make clear what outcome you are seeking

Your companion can address the hearing on your behalf, present your case, and raise concerns about how the appeal is being conducted. Brief them properly in advance.

If significant new evidence is raised or a procedural issue comes to light during the hearing, the employer may pause the process to investigate further before reaching a decision. This is appropriate where the new issue is material to the outcome.

Your Right to Be Accompanied at Work Hearings

Possible Outcomes of the Appeal

After the hearing, your employer should communicate the outcome in writing. Possible outcomes include:

Appeal upheld — the original decision is overturned, the sanction is removed, or the grievance is upheld
Appeal partially upheld — the sanction is reduced, for example from dismissal to a final written warning, or from a final to a first written warning
Further investigation ordered — where new evidence or a procedural issue requires the matter to be looked at again before a final decision is made
Appeal dismissed — the original decision is confirmed

Whatever the outcome, it should be communicated in writing with reasons. An outcome that simply confirms the original decision without engaging with the grounds you raised is not an adequate appeal response.

The Employment Tribunal Time Limit — Do Not Wait

This is one of the most important things to understand about the appeal stage: the internal appeal process does not pause the employment tribunal time limit.

If you have been dismissed — or if your situation may give rise to a tribunal claim — the three months minus one day clock starts running from the effective date of termination, regardless of whether your internal appeal is still ongoing.

You must contact ACAS and begin early conciliation within that time limit. ACAS early conciliation then pauses the clock while conciliation is attempted. If conciliation does not resolve the matter, ACAS issues a certificate and you have a further period to submit a claim.

Do not wait until your appeal is concluded before checking your tribunal deadline. If dismissal is involved, work out the deadline immediately and put steps in place to meet it — even if the appeal is still in progress.

What to Do If Your Employer Does Not Offer a Right of Appeal

If your employer has not offered a right of appeal, or has conducted the appeal in a way that is clearly not independent — for example, the same person hearing the appeal who issued the original outcome — that is a direct departure from the ACAS Code.

In this situation:

write to your employer formally noting that you have not been provided with a right of appeal as required by the ACAS Code and, where applicable, your employer's own procedure
keep a copy of that letter as part of your record
seek independent advice about whether the failure to offer an appeal affects any subsequent tribunal claim

An employer who fails to offer a genuine right of appeal has acted outside the expected standard. That failure is relevant to any tribunal assessment of whether the overall process was fair.

Start Your Record Immediately

If you have not already been keeping a contemporaneous record, start now. Everything that happens from this point — the appeal submission, the hearing, the outcome — should be documented.

For each relevant event, note:

the date, time, and location
what happened or what was said, as accurately as possible
who was involved or present
how it affected you
any action you took and any response you received

Alongside your notes, keep copies of:

your appeal letter and the date it was submitted
all correspondence with HR or management about the appeal
the original disciplinary or grievance outcome letter
all documentation from the original process
notes of what was said at the appeal hearing, made as soon as possible afterwards
the written outcome of the appeal

Keep everything on a personal device and a personal email account, not on work equipment or systems.

FAQ

How long do I have to submit my appeal?

Most employers set a deadline of around five working days from the date you receive the written outcome. Check your employer's disciplinary or grievance procedure carefully — the deadline is set there. If the policy is silent, submit your appeal within five working days as a general guide. Do not miss the deadline.

What if I miss the appeal deadline?

Missing the internal appeal deadline does not necessarily prevent you from pursuing other options, but it may affect any subsequent tribunal claim — a tribunal may take into account that you did not use the appeal process when it was available. If you have missed the deadline, seek independent advice about your options without delay.

Can I introduce new evidence at the appeal stage?

Yes. New evidence — documents, witness accounts, or other information that was not available at the time of the original hearing — can be introduced at the appeal. The appeal hearing is the appropriate place to raise it.

Does the internal appeal pause the employment tribunal time limit?

No. The three months minus one day tribunal time limit runs from the effective date of termination regardless of whether an internal appeal is still ongoing. Do not wait until your appeal concludes before checking and acting on your tribunal deadline.

The same person who issued the original outcome is hearing my appeal. Is that acceptable?

No. The ACAS Code and most employers' own procedures require the appeal to be heard by someone not involved in the original decision. Where the same person hears both, the independence of the appeal is compromised. Raise this in writing before the hearing and note it formally at the start of the appeal hearing.

What if my employer doesn't offer a right of appeal?

An employer who fails to offer a right of appeal has departed from the ACAS Code. Write to your employer formally noting this failure and keep a copy. Seek independent advice about the effect on any tribunal claim — the failure to offer an appeal is directly relevant to whether the overall process was fair and to how any compensation might be affected.

Should I appeal even if I think it will not succeed?

Yes, in almost every case. An employee who does not use an available right of appeal may have any subsequent tribunal compensation reduced by up to 25 percent. An appeal also creates a further formal record of the concerns and gives your employer another opportunity to correct a flawed decision. The grounds for appeal and how the appeal is conducted also matters — a well-prepared appeal is not the same as a poorly-presented one.

Can Ark Advocacy attend the appeal hearing with me?

Yes. Ark Advocacy attends disciplinary and grievance appeal hearings as companion and representative for employees across Scotland. Where your employer's procedure permits it, we can represent you directly at the hearing, address it on your behalf, and raise procedural concerns formally on the record.
