Gross Misconduct Dismissal Letter: What to Include and What to Avoid

A gross misconduct dismissal involves up to four separate letters, each serving a distinct legal purpose at a specific stage of the process. Getting any one of them wrong creates procedural risk, even where the underlying conduct is clear. Knowing which letter to issue at each stage, what it must contain and what you should never include is the difference between a defensible dismissal and an avoidable tribunal claim. This guide tells you what each letter needs to say, with plain English example wording for every stage.

These examples are for guidance only. They are not legal documents and are not a substitute for advice specific to your situation.

The four letters in a gross misconduct process

A gross misconduct case requires up to four written communications:

The suspension letter is issued at the start, when you suspend the employee pending investigation.

The disciplinary hearing invitation letter is issued once the investigation is complete, calling the employee to a formal hearing.

The outcome letter confirms the result of the hearing. Where the outcome is dismissal, this is the dismissal letter.

The appeal outcome letter confirms the result of any appeal the employee makes.

Each of these documents has different legal requirements. Using the wrong letter at the wrong stage or combining stages into a single letter, creates procedural problems that are difficult to correct afterwards.

Letter one: the suspension letter

Issue this on the same day as the verbal suspension notification. The suspension letter covers the fact and terms of the suspension only. It should not include a detailed account of the allegation or any language that suggests a conclusion has already been reached.

What to include:

• →The date the suspension starts
• →Confirmation that it is on full pay
• →A clear statement that this is a neutral act and not a disciplinary sanction
• →What the employee must not do during the suspension (attending the workplace, contacting colleagues or customers without prior agreement)
• →The expected duration or review date
• →Who the employee should contact if they have questions

Example wording:

Dear [Name],

I am writing to confirm that you are suspended from work with immediate effect from [date], pending an investigation into a matter that has come to our attention.

This suspension is on full pay. It is a neutral act to allow us to carry out a thorough investigation and should not be taken as a finding that any misconduct has occurred.

During the suspension, please do not attend the workplace or contact colleagues or customers without prior written agreement from me. If you have any queries, you may contact me directly at [contact details].

We anticipate reviewing this matter within [timeframe]. We will keep you updated as the investigation progresses.

Yours sincerely, [Your name]

What to avoid: language suggesting the outcome is predetermined, conclusions stated as fact before the investigation is complete and a stated suspension period so long that it appears to be a sanction in itself.

Letter two: the disciplinary hearing invitation letter

This letter is issued once the investigation is complete. It formally invites the employee to the disciplinary hearing where their conduct will be considered. This letter triggers the formal disciplinary process.

What to include:

• →The specific allegation in clear, factual terms
• →Reference to the evidence you intend to rely on, with copies attached or access confirmed
• →The date, time and location of the hearing, with at least 48 hours notice
• →The employee's right to be accompanied by a trade union representative or a work colleague
• →A clear statement that dismissal is a potential outcome of the hearing
• →Instructions for requesting a postponement if needed

Example wording:

Dear [Name],

Following our investigation, I am writing to invite you to a disciplinary hearing to discuss the following concern:

[State the specific allegation - for example: "On [date], it is alleged that you removed materials from a customer's property at [address] without authorisation."]

The hearing will take place on [date] at [time] at [location].

You have the right to be accompanied by a trade union representative or a work colleague of your choice. Please let me know in advance if you intend to bring a companion.

I enclose copies of the evidence I intend to rely on at the hearing. Please review this before the meeting.

The possible outcomes of this hearing include a first written warning, a final written warning or dismissal. You will have a full opportunity to respond to the concern raised.

If you are unable to attend on the proposed date, please contact me as soon as possible so we can arrange an alternative within five working days.

Yours sincerely, [Your name]

What to avoid: vague allegations that do not specify the conduct, failure to attach or clearly reference the evidence, omitting the right to be accompanied and omitting the statement that dismissal is a possible outcome.

Letter three: the outcome letter (dismissal)

This is the formal dismissal letter. Issue it within one to two working days of the decision. Keep the tone factual throughout. This letter may be read by an employment tribunal.

What to include:

• →Confirmation that a hearing took place and the date it occurred
• →The allegation that was considered
• →Your finding: that the conduct occurred on the balance of probabilities
• →Why dismissal is the outcome
• →Confirmation that the dismissal is without notice, as this is a gross misconduct dismissal
• →The date employment ends
• →Outstanding payments: accrued but untaken holiday pay must be paid and should be referenced
• →The right of appeal, who to appeal to, how to appeal and the deadline

Example wording:

Dear [Name],

Further to the disciplinary hearing held on [date], I am writing to confirm the outcome.

At the hearing, I considered the allegation that [restate the allegation]. You had the opportunity to respond fully to this concern [and were accompanied by [name] / and attended alone].

Having considered all of the evidence and your response at the hearing, I have concluded on the balance of probabilities that [the conduct occurred as alleged]. I am satisfied that this conduct amounts to gross misconduct and that dismissal is the appropriate outcome.

Your employment is therefore terminated with immediate effect from [date]. As this is a dismissal for gross misconduct, you are not entitled to a notice period or payment in lieu of notice. Your final pay, including [x days of accrued holiday pay at [daily rate]], will be processed on [date].

You have the right to appeal this decision. If you wish to appeal, please write to [name] within five working days of receiving this letter, setting out the grounds on which you are appealing.

Yours sincerely, [Your name]

What to avoid: apologetic or uncertain language, unnecessary detail about the investigation process, any reference to off-the-record conversations, language that reveals the decision was made before the hearing and failure to include the appeal details.

Letter four: the appeal outcome letter

If the employee appeals, a separate letter confirms the result of the appeal hearing. Where possible, the appeal should be heard by someone who was not involved in the original decision.

What to include:

• →Acknowledgement of the grounds of appeal the employee raised
• →Confirmation of who heard the appeal and when
• →The decision: whether the dismissal is upheld, varied or overturned
• →If upheld, confirmation that the original decision stands and why
• →If overturned, confirmation of the revised outcome
• →Confirmation that this is the final stage of the internal process

Example wording (dismissal upheld):

Dear [Name],

Thank you for your appeal against the decision to dismiss you, which was received on [date].

Your appeal was heard by [name] on [date]. The grounds of your appeal were carefully considered.

Having reviewed the matter in full, the decision to dismiss you for gross misconduct is upheld. The original decision stands.

This concludes the internal appeal process.

Yours sincerely, [Your name]

What to avoid: dismissing the appeal without genuinely engaging with the grounds raised, using the same person to hear the original case and the appeal where this could have been avoided and failing to confirm the outcome in writing.

The difference between each letter at a glance

| Stage | Letter | Purpose | |---|---|---| | Before investigation | Suspension letter | Removes employee from workplace on full pay | | After investigation | Hearing invitation | Calls employee to formal hearing | | After hearing | Outcome letter | Confirms the decision and any sanction | | After appeal | Appeal outcome | Confirms result of appeal |

Using a suspension letter as a de facto dismissal letter or combining the hearing invitation with the outcome letter, creates procedural failures that are difficult to undo once a claim is filed.

A note on these examples

The wording in this guide is for general information only. It illustrates the correct structure and the elements that each letter must contain. It is not a substitute for letters drafted to reflect the specific facts of your situation. The language you use should reflect the actual allegation, the actual evidence and the actual outcome of your hearing. These examples should not be used as legal documents without amendment and review specific to your case.
