Conduct and discipline

Summary dismissal for gross misconduct letter

Dismisses without notice for a single act of gross misconduct found at a disciplinary hearing.

The hearing has found an act serious enough to destroy the employment relationship on its own: theft, violence, serious safety breaches, gross insubordination, serious dishonesty. The invitation letter said summary dismissal was possible. No notice is paid, but everything else owed is.

Before it goes

  • Your disciplinary procedure lists examples of gross misconduct and this fits.
  • The invitation letter named summary dismissal as a possible outcome and enclosed the evidence.
  • You have genuinely considered whether it is gross misconduct rather than misconduct, and whether any mitigation changes that.

The letter

[COMPANY NAME] [COMPANY ADDRESS] [DATE] [EMPLOYEE NAME] [EMPLOYEE ADDRESS] Dear [EMPLOYEE FIRST NAME], Outcome of disciplinary hearing: summary dismissal I am writing to confirm the outcome of the disciplinary hearing held on [HEARING DATE], chaired by me, at which you were accompanied by [COMPANION NAME / at which you chose not to be accompanied]. The allegation considered was: [ALLEGATION, as stated in the invitation letter.] Having considered the evidence and your response, in particular [WHAT THEY SAID], I have concluded that the allegation is upheld, because [REASONING]. I have concluded that your conduct amounts to gross misconduct, because [WHY IT IS GROSS: e.g. it was a deliberate breach of a safety rule that put others at serious risk / it involved dishonesty in relation to company money / it was an act of violence towards a colleague]. I have considered the points you raised in mitigation, including [MITIGATION], and whether any lesser sanction would be appropriate, and concluded that the conduct has fundamentally broken the trust necessary for the employment to continue. You are therefore summarily dismissed with effect from [DATE, the date this decision is communicated]. You are not entitled to notice or pay in lieu of notice. Your final pay will include pay to [DATE] and payment for [NUMBER] days of accrued but untaken holiday, less any lawful deductions. Your P45 will follow by post. Please return [COMPANY PROPERTY] to [NAME] by [DATE]. You have the right to appeal against this decision. If you wish to appeal, write to [APPEAL MANAGER NAME] at [ADDRESS / EMAIL] within five working days of receiving this letter, setting out your grounds of appeal.

Filling it in

Why it is gross
This paragraph is the whole case. Deliberate, serious, trust-destroying: say which and why, in terms of what actually happened.
Effective date
The day the decision is told to them, in the meeting or by this letter, whichever first. Not the date of the incident and not the hearing date.

What the law says

  • Employment Rights Act 1996 s.98: conduct as a potentially fair reason; the decision must be reasonable.
  • Employment Rights Act 1996 s.86(6): notice need not be given where the employee's conduct entitles the employer to terminate without notice.
  • Working Time Regulations 1998 reg.14: accrued statutory holiday is paid on termination whatever the reason.
  • Acas Code of Practice on disciplinary and grievance procedures: a tribunal can adjust compensation by up to 25% for an unreasonable failure to follow it.
Guidance, not legal advice. Employment law moves; check the current position before relying on any of it, and take advice on anything that could end someone's employment.

What turns this letter into a claim

  • Do not sack on the spot. Even for the clearest gross misconduct, suspend, investigate, invite, hear, decide. A day or two of process is what makes the dismissal fair.
  • Do not withhold accrued holiday pay as a punishment. It is owed regardless.
  • Do not describe something as gross misconduct because you are angry. If it would not be on the list in your own procedure, it is probably misconduct.

Questions people ask

What counts as gross misconduct?

Conduct so serious it justifies dismissal without notice for a single act: theft, fraud, physical violence, serious breach of safety rules, being under the influence at work, serious insubordination, serious breach of confidence. Your disciplinary procedure should give non-exhaustive examples, and this letter should fit them.

Do I still have to pay anything?

Everything except notice. Pay to the date of dismissal, accrued holiday, any expenses owed. Deductions only where the contract allows and the law permits.
