Gross Misconduct meaning

/ɡrəʊs/ /mɪsˈkɒndʌkt/
What does Gross Misconduct mean?
In employment practice, gross misconduct describes employee behaviour so serious that it destroys trust and confidence, amounts to a repudiatory breach of the employment contract and may justify summary dismissal (dismissal without notice or payment in lieu). It is not defined in statute; its meaning arises from contract and case law, with guidance from the ACAS Code of Practice (England & Wales, Scotland), the Labour Relations Agency (Northern Ireland) and the Irish Code of Practice on Grievance and Disciplinary Procedures. Examples commonly cited in contracts/handbooks include theft or fraud, violence or threats, harassment or discrimination, serious insubordination, gross negligence, serious health and safety breaches, intoxication at work, unauthorised disclosure of confidential information, and conduct bringing the employer into serious disrepute. Lists should be illustrative, not exhaustive. An employer alleging gross misconduct must still follow a fair disciplinary procedure: reasonable investigation, written allegations, a hearing, the opportunity to respond and appeal. Tribunals/courts assess reasonableness and proportionality; the label “gross misconduct” is not determinative. The legal framework is broadly consistent across the UK (Employment Rights Act 1996; Employment Rights (Northern Ireland) Order 1996) and Ireland (Unfair Dismissals Acts 1977–2015). If dismissal is upheld, notice is forfeited, but accrued statutory/contractual entitlements (e.g. wages earned, holiday...

England and Wales Court of Appeal in Hewston v Ofsted: unfair dismissal; no fair notice for single, non-safeguarding touch; lack of contrition cannot elevate misconduct; procedural non-disclosure

Andrew Hewston v OFSTED (Office for Standards in Education, Children's Services and Skills) [2025] EWCA Civ 250 What are the practical implications of this judgment? In this ruling, the Court of Appeal, with Lord Justice Underhill delivering the lead judgment, confirmed the EAT’s finding that the claimant’s dismissal was unfair, where he neither understood nor could reasonably have been expected to understand that a single episode of conduct could lead to dismissal. The decision also restates the key principles employers should apply when dismissing for gross misconduct. Notably, the Court agreed with the EAT that, where the conduct on its own does not justify dismissal, it is not reasonable for an employer to elevate its gravity solely because the employee failed to demonstrate adequate contrition or insight. Underhill LJ made a comparable observation in the recent case of Higgs v Farmor at [165]–[166], highlighting that conduct reflecting a deeply held belief may mean an employee is reluctant to accept it was wrong, or seriously wrong.

Executive Service Agreements (UK): Clause-by-Clause Drafting and Negotiation Playbook with Preferred/Fallback Positions, Risks and Guidance for Directors and Senior Employees

Employment This playbook sets out guidance for preparing and negotiating an executive service agreement for a director or senior hire. It presents a preferred stance and an alternative fall-back for the clauses most often debated, but it will not necessarily capture every point that might surface in a specific negotiation. The template is suitable for lawyers acting for the employer and for in-house counsel. Users should adapt it to reflect the client’s circumstances and to safeguard the client’s position. The risk level indicated may differ according to the client.

Conduct in financial remedy proceedings: thresholds, impact on awards, add-backs, litigation misconduct, bigamy/public policy, procedure and costs (England and Wales)

Conduct Under section 25(2)(g) of the Matrimonial Causes Act 1973 (MCA 1973) and Schedule 5, Part 5 of the Civil Partnership Act 2004 (CPA 2004) — specifically CPA 2004, Sch 5 Pt 5, para 21(2)(g) — conduct is a distinct consideration where, in the court’s opinion, it would be inequitable to disregard it. The legislation therefore expressly invites the court to assess the parties’ behaviour when determining a financial award. This, in turn, can encourage parties to set out extensive allegations of each other’s poor behaviour; Form E even asks for such details, but with the caveat that misconduct will only be taken into account ‘in very exceptional circumstances’. Clients are often keen to pursue conduct-based arguments. However, within financial order proceedings, conduct is rarely of real relevance, and firm, early advice should be provided accordingly. Clients should be informed of the court’s approach to conduct and why, in most cases, it is not usually factored into the decision...

Gross misconduct in employment: fundamental breach, gross negligence, and the interplay between wrongful dismissal, unfair dismissal and disciplinary rules (Great Britain)

This Practice Note examines what is meant by gross misconduct in the context of wrongful dismissal ie summary dismissal or termination on short notice or no notice This note explores gross misconduct within wrongful dismissal, meaning summary dismissal or ending employment on short or no notice. It considers fundamental breach of contract, conduct at odds with the duty of fidelity and/or the duty of trust and confidence, serious misconduct, gross negligence, and disciplinary rules. It also addresses misconduct for unfair dismissal purposes. Gross misconduct is behaviour by an employee so serious that the employer cannot reasonably be expected to continue the employment relationship. It must amount to a fundamental breach—one that strikes at the core of the contract. The conduct must be both gross (that is, extreme or out of the ordinary) and culpable (blameworthy). It is behaviour incompatible with the employee’s obligations of fidelity, trust and confidence, for example dishonesty or acts intended to harm the employer’s interests. A pattern of incidents may, when viewed together, be...

Summary dismissal appeal: bail bars witness contact—proceed/adjourn?

Unfair dismissal—conduct and procedure Where an employee pursues an unfair dismissal claim, the onus lies with the employer to demonstrate a fair reason for ending employment. Conduct is one of the potentially fair grounds, but a fair process must also be observed. Ultimately, it needs to be established that dismissal is an appropriate and fair sanction. The Acas Code of Practice on Disciplinary and Grievance Procedures imposes duties on both employers and employees to follow its provisions, with possible sanctions for non-compliance. It describes the standard of reasonable behaviour expected in most situations. For further guidance, see the following Practice Notes: Dismissing fairly for conduct reasons Reason for dismissal—conduct Reason for dismissal—general, in particular section: Potentially fair reasons Acas disciplinary and grievance code—procedural requirements Under the Acas Code of Practice, certain actions—labelled gross misconduct—are so serious in themselves, or carry such serious consequences, that they may justify dismissal without notice even for a first offence.

PHI Appeal: Does the Incapacity Implied Term Bar Dismissal?

You may wish to consider separately: the implied term the fairness of a dismissal which prejudices Permanent Health Insurance (PHI) rights, under the statutory law on unfair dismissal Where PHI benefits depend on employment continuing, the High Court has implied a term preventing dismissal during incapacity, save for summary dismissal (gross misconduct) or another compelling ground (eg redundancy). In Briscoe v Lubrizol, the Court of Appeal signalled a broader carve-out, permitting dismissal for ‘reasonable and proper cause’. Even so, such a term is not always to be implied. In Lloyd v BCQ (EAT) no implication was made where: a later written contract omitted any reference to the PHI scheme and contained an entire agreement clause there was, overall, no contractual entitlement to scheme benefits the contract expressly permitted dismissal for prolonged illness For more detail, including reconciling Briscoe and Lloyd, see Practice Notes: Dealing with long-term or chronic sickness—Consider any Permanent Health Insurance (PHI)...
