Gross misconduct can justify dismissal without notice, but it does not mean “dismiss first, investigate later”. GOV.UK and Acas both emphasise that employers should still investigate and follow a fair procedure.
The director’s risk is often not the seriousness of the allegation — it is treating an allegation as a proven fact too early.
Gross misconduct is a category, not a shortcut
Policies commonly give examples such as theft, violence, fraud or serious insubordination. The actual facts still matter. The employer should establish what happened and whether it falls within the organisation’s rules and the reasonable understanding of gross misconduct.
Avoid relying on a label before the investigation is complete.
Investigate proportionately
Gather relevant documents, witness accounts, CCTV or system records where lawful and necessary. The investigation should look for evidence that supports and undermines the allegation.
A predetermined investigation creates risk because the later hearing becomes little more than a formality.
Suspension is not automatic
Some allegations require the employee to be away from the workplace while facts are gathered. Others do not. Consider whether temporary changes, restricted duties or remote work could manage the risk.
Where suspension is used, communicate that it is a neutral step rather than a disciplinary sanction.
Give the employee the case to answer
Before the hearing, explain the allegation and provide enough information for the employee to prepare. At the meeting, listen to the explanation and test any new facts raised.
If significant new evidence emerges, adjourn and investigate rather than forcing the process to a conclusion.
Decide on the evidence and proportionality
The decision-maker should consider whether there is a reasonable belief, based on the investigation, that the misconduct occurred and whether dismissal is a proportionate sanction in the circumstances.
Length of service, disciplinary record, consistency and mitigation may all be relevant depending on the case.
Do not forget the appeal
A fair process normally includes an appeal. Where practicable, the appeal should be handled by someone who has not previously been involved.
The appeal is not just administrative. It is an opportunity to correct factual or procedural errors before the dispute escalates.
The Guardian Forge view
The words “gross misconduct” often make managers move faster when they should become more disciplined. Serious allegations deserve a process that can withstand scrutiny.
Speed can matter, but speed and fairness are not opposites.
