What is a gross misconduct or summary dismissal letter?

Gross misconduct or summary dismissal letter template preview

This letter provides a formal written record where an employer has concluded, following a disciplinary process, that an employee's conduct amounts to gross misconduct and that dismissal without notice is an appropriate outcome. It is designed to clearly explain the decision while preserving a proper distinction between the allegation, the evidence considered, the employee's response and the final findings.

Confirming the disciplinary outcome

The letter records that the disciplinary process has been completed and confirms the decision reached by the authorised decision-maker. It should make clear that the decision was reached after consideration of the evidence and the employee's response.

Explaining why the conduct was gross misconduct

The employer should identify the conduct found to have occurred and explain why it was considered sufficiently serious to amount to gross misconduct under the organisation's disciplinary rules, policies or contractual requirements.

Recording the dismissal decision

Where summary dismissal is decided upon, the letter confirms that employment ends without notice or payment in lieu of notice. It should also explain what payments remain due, including unpaid wages and accrued but untaken holiday where applicable.

Considering the circumstances

The decision should reflect the circumstances of the individual case, including the evidence, employee's explanation, seriousness of the conduct, relevant policies, previous disciplinary record where appropriate and any mitigating factors that were raised during the process.

Providing a right of appeal

The employee should be given a clear opportunity to appeal. The appeal should normally be considered by someone who has not previously been involved in the disciplinary decision, wherever possible.

Example

An employee was investigated following an allegation of serious misconduct involving a significant breach of the organisation's workplace rules. The investigation gathered witness statements, relevant records and other available evidence, and the employee was invited to a formal disciplinary hearing.

At the hearing, the employee was given an opportunity to respond to the allegation, challenge the evidence and provide any explanation or mitigating circumstances. The decision-maker considered the employee's explanation alongside the investigation findings and the organisation's disciplinary rules.

The decision-maker concluded that the allegation was substantiated and that the conduct was sufficiently serious to amount to gross misconduct. The organisation considered whether a lesser disciplinary sanction would be appropriate but concluded that the seriousness and circumstances of the conduct justified dismissal without notice.

A written outcome letter was issued confirming summary dismissal, the effective termination date, arrangements for final pay and accrued holiday, the return of company property and the employee's right to appeal. The appeal was to be considered by an appropriate manager who had not previously been involved in the case.

HR considerations

UK employment law and best practice

This template is designed to support the process, but the document should be used alongside the relevant HR procedure and applied to the circumstances of the individual case.

Gross misconduct and summary dismissal

Gross misconduct refers to conduct that is sufficiently serious, or has sufficiently serious consequences, that it may justify dismissal without notice. Examples can include fraud, physical violence, gross negligence and serious insubordination, although organisations should define their own examples within their disciplinary rules. https://www.acas.org.uk/dismissals/types-of-dismissal

A fair disciplinary procedure is still required

An employer should not treat gross misconduct as meaning that a disciplinary process can simply be skipped. Acas states that a fair disciplinary process should be followed before deciding to dismiss for gross misconduct. This normally includes investigation, notification of the allegations, a disciplinary hearing and an opportunity for the employee to respond. https://www.acas.org.uk/acas-code-of-practice-on-disciplinary-and-grievance-procedures/html

Investigating the allegation

The employer should carry out a reasonable investigation and consider relevant evidence before reaching a decision. The investigation should be sufficiently thorough to establish the relevant facts and should not simply be designed to prove the allegation. https://www.acas.org.uk/disciplinary-procedure-step-by-step

Considering the employee's response

The employee should be told what they are accused of and given a reasonable opportunity to respond to the allegation and evidence at a disciplinary hearing. Employees have a statutory right to be accompanied at disciplinary hearings in qualifying circumstances. https://www.gov.uk/taking-disciplinary-action/disciplinary-hearings

Proportionality and the disciplinary outcome

The decision-maker should consider whether dismissal is reasonable in all the circumstances, taking account of the seriousness of the conduct, the evidence, the employee's explanation, relevant policies and rules, and any mitigating circumstances. Acas guidance states that dismissal should be decided by someone with appropriate authority. https://www.acas.org.uk/disciplinary-procedure-step-by-step/step-5-deciding-on-the-disciplinary-outcome

Dismissal without notice

Where summary dismissal is justified, the employee's employment ends without a notice period and they do not normally receive notice pay. The employer must still pay sums properly due, including unpaid wages and accrued but untaken holiday, subject to the circumstances and applicable contractual arrangements. https://www.acas.org.uk/dismissals/dismissals-with-and-without-notice

Right of appeal

The employee should be given a right of appeal against the disciplinary outcome. Wherever possible, the appeal should be dealt with impartially by someone who has not previously been involved in the case. https://www.acas.org.uk/acas-code-of-practice-on-disciplinary-and-grievance-procedures/html

Written disciplinary rules

Employers should clearly set out their disciplinary rules and examples of conduct that may amount to gross misconduct. The rules should also explain the possible consequences of disciplinary action and the appeal arrangements. https://www.gov.uk/taking-disciplinary-action/writing-disciplinary-proceedings

Discrimination and protected circumstances

The employer should ensure that the disciplinary decision is not influenced by a protected characteristic or another legally protected activity. Where an issue may relate to disability or health, the employer should consider whether additional information, support or reasonable adjustments are relevant before reaching a decision. https://www.gov.uk/employment-status/employee-rights-and-discrimination

FAQs

Can an employee be dismissed for gross misconduct without a previous warning?

Yes. Gross misconduct can be sufficiently serious to justify dismissal without a previous warning. However, the employer should still investigate the allegation and follow a fair disciplinary procedure before deciding on dismissal.

Does gross misconduct automatically mean summary dismissal?

No. A finding of gross misconduct does not mean that dismissal is automatically the only possible outcome. The decision-maker should consider the circumstances, evidence, employee response, mitigating factors and the organisation's disciplinary rules before deciding the appropriate outcome.

Does summary dismissal mean the employee receives no final pay?

No. Summary dismissal normally means that the employee does not receive notice pay, but wages already earned and accrued but untaken holiday will normally still need to be paid.

Should the employee be allowed to appeal?

Yes. A disciplinary dismissal letter should normally provide a clear right of appeal and explain how and when the employee should submit their appeal.

Who should hear an appeal against summary dismissal?

Wherever possible, the appeal should be heard by someone who has not previously been involved in the disciplinary process and who has appropriate authority to review the decision.
