Gross Misconduct: Investigation and Action
These templates are designed to help employers investigate serious conduct issues and, where appropriate, dismiss for misconduct or gross misconduct using a fair and properly documented process.
Some employee conduct issues may justify formal disciplinary action and, in the most serious cases, may amount to gross misconduct that could lead to summary dismissal. Employers should deal with those situations carefully and consistently to reduce the risk of allegations of unlawful discrimination, constructive dismissal, or procedurally unfair dismissal.
This collection supports the key stages of that process, from the initial investigation and early communications through to formal hearings, escalating warnings, and dismissal. It is intended to work alongside a disciplinary policy and procedure and related guidance on disciplinary handling.
Gross Misconduct and Serious Misconduct Procedures
These templates are useful where an employer needs to investigate allegations of serious misconduct, decide whether formal disciplinary action is justified, and manage the process through to an appropriate outcome.
They cover the progression from fact-finding and informal intervention to formal disciplinary action, further hearings where conduct does not improve, and dismissal where that is warranted. They also include documents specifically aimed at gross misconduct scenarios, where the allegations may be serious enough to place continued employment at immediate risk.
Supporting Fairness and Consistency
Having a clear written framework for handling serious conduct issues can help employers act more consistently and demonstrate procedural fairness. That is important both for day-to-day management and for reducing the scope for later disputes about how an employee was treated.
The templates in this collection are drafted to reflect good practice and to align with UK employment law principles, including the Employment Rights Act 1996 and the ACAS Code of Practice.
A Structured Route from Investigation to Dismissal
Taken together, these documents provide practical support for the main stages of serious misconduct handling: investigation, formal disciplinary meetings, warnings, escalation, suspension in gross misconduct cases, and dismissal.
They are intended to help employers and HR teams keep the process organised, communicate clearly with employees at each stage, and maintain appropriate records throughout.

Frequently Asked Questions
An employee may have committed a very serious act at work. Can I dismiss them immediately or do I still have to follow a disciplinary process? +
Yes, you can dismiss them immediately without notice where the conduct amounts to gross misconduct, but only if you still follow a fair procedure. With gross misconduct you can dismiss the employee immediately as long as you follow a fair procedure. The Acas Code of Practice requires you to investigate, put the allegations in writing, hold a disciplinary hearing (at which the employee may be accompanied), consider their response and offer a right of appeal before any decision. Skipping those steps exposes you to an unfair dismissal claim even if the conduct was genuine. The Simply-Docs collection supports each stage, from the investigation through to the notice of dismissal.
What documents do I need when handling a gross misconduct case from investigation through to possible dismissal? +
Match each document to the stage you are at: a suspension letter if you suspend pending investigation, a written notice of the disciplinary meeting setting out the allegations and evidence, and a notice of dismissal once a decision is made (or a separate misconduct dismissal letter if the outcome is misconduct rather than gross misconduct). Simply-Docs provides a Gross Misconduct Suspension Letter, a Gross Misconduct Notice of Disciplinary Meeting, a Gross Misconduct Notice of Dismissal and a Misconduct Notice of Dismissal, intended to work alongside a disciplinary policy and procedure.
Should I suspend an employee I suspect of gross misconduct, and if so do I have to pay them during the suspension? +
Suspension is not automatic and should only be considered where there is a genuine reason, such as a risk that the employee could interfere with the investigation, influence witnesses or cause harm. The Acas Code of Practice makes clear it should be kept as brief as possible, kept under review and not presented as a disciplinary sanction or an assumption of guilt. As a general rule, suspension pending investigation should be on full pay unless your contract clearly permits otherwise. The Simply-Docs Gross Misconduct Suspension Letter communicates the suspension correctly.
What is the difference between misconduct and gross misconduct, and does it affect which letter I should use for dismissal? +
Gross misconduct is conduct so serious it destroys trust and confidence, justifying summary dismissal without notice. Acas examples include theft, fraud, physical violence, gross negligence and serious insubordination, though there is no fixed statutory list and context matters. Ordinary misconduct may warrant warnings but would not normally justify dismissal for a first offence. The distinction affects the letter. For gross misconduct, where the employee gets no notice pay (though you must still pay accrued wages and unused holiday), use the Gross Misconduct Notice of Dismissal. When dismissing for misconduct after an escalating warning process, use the Misconduct Notice of Dismissal.
What should the notice of a gross misconduct disciplinary meeting include, and is the employee entitled to bring someone with them? +
The written notice should set out the allegations in sufficient detail, refer to the evidence gathered during the investigation, confirm the date, time and venue of the hearing and make clear the possible outcomes (including dismissal). Under the Acas Code of Practice, the employee has a statutory right to be accompanied at a formal disciplinary hearing by a colleague or trade union representative, whether or not they are ultimately found to have committed gross misconduct. The Simply-Docs Gross Misconduct Notice of Disciplinary Meeting template covers these requirements.
