Gross misconduct is the most serious category of employee wrongdoing. It refers to acts that are so fundamental a breach of the contract of employment that the employer is entitled to dismiss the employee immediately — without notice or pay in lieu of notice. However, the process of reaching that decision must still be fair.
Common Examples
- Theft or fraud — stealing from the employer, clients, or colleagues, or committing financial fraud
- Physical violence — assault or fighting in the workplace
- Serious insubordination — a deliberate and significant refusal to follow legitimate instructions
- Gross negligence — reckless behaviour that causes or could cause serious harm, damage, or financial loss
- Serious breach of health and safety rules — endangering themselves or others
- Drug or alcohol abuse — being intoxicated at work or using illegal substances on the premises
- Serious harassment or bullying — including sexual harassment or discriminatory behaviour
- Breach of confidentiality — disclosing sensitive company information or trade secrets
- Serious damage to company property — deliberate or reckless destruction
- Criminal conduct — offences that affect the employee's suitability for their role or the employer's reputation
Important Considerations
Context Matters
Whether an act constitutes gross misconduct depends on the circumstances. What qualifies in one workplace may not in another. For example, a single instance of poor language may be gross misconduct in a school but not on a construction site. The employee's role, length of service, and any mitigating factors should all be considered.
Your Disciplinary Policy
Your employee handbook should include a non-exhaustive list of examples of gross misconduct. This sets expectations and strengthens your position if dismissal is challenged. The list should be described as "including but not limited to" — you cannot anticipate every possible scenario.
Investigation Is Still Required
Even when the misconduct seems obvious, you must still investigate and hold a formal disciplinary hearing. Dismissing on the spot without investigation is a frequent cause of successful unfair dismissal claims.
Suspension
Where the alleged misconduct is serious, it may be appropriate to suspend the employee on full pay while the investigation takes place. Suspension should not be used as a punishment — it is a neutral act to allow a fair investigation. It should be as brief as possible and reviewed regularly.
