Insubordination occurs when an employee deliberately refuses to follow a lawful and reasonable instruction from a manager, or behaves in a way that is openly defiant or disrespectful towards authority. While occasional disagreements or misunderstandings may be manageable through informal conversations, serious insubordination presents a far greater risk. It can undermine managerial authority, disrupt workplace order, and, in some cases, amount to gross misconduct.
For employers, HR teams, and line managers, recognising and handling serious insubordination correctly is essential. Poorly managed cases can lead to operational disruption, inconsistent standards, employee relations challenges, and legal risk.
Kingfisher Professional Services supports employers with expert HR and employment law advice, helping them navigate misconduct issues and maintain clear, fair, and legally compliant workplace standards.
What Is Insubordination?
Ordinary Insubordination
In a workplace context, insubordination refers to the deliberate refusal of an employee to follow a lawful, reasonable instruction given by a manager or authorised superior. It may also include disrespectful, argumentative, or defiant behaviour that challenges authority.
Examples of ordinary insubordination include:
- Refusing to complete a reasonable task within the employee’s role.
- Ignoring direct instructions.
- Displaying disrespectful or argumentative behaviour.
- Demonstrating minor defiance or poor attitude.
However, not all insubordination is serious. Context matters, including whether the instruction was reasonable, whether the refusal was intentional, and whether the employee had valid grounds (e.g., safety concerns or unclear duties). Employers must assess proportionality before escalating the matter.
Serious Insubordination / Gross Misconduct
Serious insubordination represents a fundamental breakdown in trust and confidence. It involves wilful and significant defiance of lawful and reasonable instructions, or behaviour so disrespectful or aggressive that it becomes incompatible with continued employment.
Examples include:
- Persistent or repeated refusal to carry out core duties.
- Publicly undermining managerial authority.
- Aggressive, abusive, or threatening behaviour towards supervisors.
- Conduct that renders working relationships unmanageable.
Serious insubordination is widely recognised in UK employment practice as an example of gross misconduct, meaning it may justify summary dismissal if handled through a fair disciplinary process.
Legal & Procedural Framework: What UK Employers Must Know
Clear Disciplinary Rules and Policies
To manage insubordination effectively, employers must have a written disciplinary procedure, usually communicated via a staff handbook or contract. Policies should:
- Define misconduct, and gross misconduct.
- Provide examples, including serious insubordination.
- Outline disciplinary stages and potential sanctions.
Without clear documentation, employers may struggle to justify disciplinary outcomes, particularly dismissal. Transparent rules help ensure fairness, consistency, and legal compliance.
Fair and Consistent Procedure – Following ACAS Guidance
Even when serious insubordination appears obvious, employers must follow a fair process before taking action. UK law expects employers to:
- Conduct an impartial investigation.
- Notify the employee of allegations in writing.
- Invite them to a disciplinary hearing.
- Allow them to be accompanied by a colleague or union representative.
- Provide a right of appeal.
A fair procedure remains essential even in cases of gross misconduct. A single act of serious insubordination can justify summary dismissal, but only if:
- The instruction was lawful and reasonable.
- The refusal or behaviour was severe enough.
- The process followed was legally sound.
Failing to follow procedure may render a dismissal unfair, regardless of the misconduct.
How to Recognise Serious Insubordination: Signs & Examples
Employers should carefully assess behaviour to determine whether it meets the threshold for serious insubordination. Common indicators include:
- Refusal to carry out a lawful, reasonable contractual instruction, especially one central to the role.
- Public defiance or challenge to authority, including aggressive or abusive language.
- Repeated refusal to comply, despite prior warnings, guidance, or informal intervention.
- Behaviour damaging to trust and confidence, particularly where safety-critical roles are involved.
- Documented evidence of refusal, including emails, messages, witness accounts, or disciplinary history.
Patterns of behaviour are especially important. A single instance may be manageable, but repeated defiance demonstrates a deeper conduct issue.
Step‑by‑Step Employer Guide to Handling Serious Insubordination
Step 1: Review Policies and Contractual Obligations
Before taking action, confirm:
- Whether the employee’s duties and responsibilities are clearly defined.
- Whether the instruction given was lawful, reasonable, and within contractual scope.
- Whether the organisation’s disciplinary policy states that serious insubordination may amount to gross misconduct.
Clear policies strengthen the employer’s position and support consistency.
Step 2: Gather and Assess Evidence – Conduct an Impartial Investigation
A thorough investigation is critical. Employers should:
- Collect all relevant evidence (written instructions, emails, witness statements, performance records).
- Determine whether the refusal or behaviour was intentional.
- Consider whether the instruction was safe, lawful, and reasonable.
- Explore legitimate reasons for refusal (e.g., health & safety concerns, unclear instructions, safeguarding).
If necessary, the employee may be suspended on full pay. Suspension should always be treated as a neutral action, not a disciplinary penalty.
Step 3: Issue Formal Notice and Invite to a Disciplinary Hearing
If the investigation indicates misconduct, write to the employee to:
- Outline the allegations clearly.
- Provide supporting evidence.
- Explain potential outcomes, including dismissal.
- Invite them to a disciplinary hearing with reasonable notice.
- Inform them of their right to be accompanied.
Step 4: Conduct the Hearing Fairly
During the hearing, employers should:
- Listen impartially to both sides.
- Allow the employee to provide evidence and call witnesses.
- Ask clarifying questions.
- Assess context, seriousness, intent, and any mitigating factors.
- Evaluate whether the misconduct amounts to serious insubordination or gross misconduct.
Maintaining objectivity is crucial to avoiding unfair dismissal claims.
Step 5: Decide the Outcome – Proportionate Sanction or Dismissal
Possible outcomes include:
- No further action.
- Informal management guidance.
- Written or final written warning.
- Dismissal with notice.
- Summary dismissal (without notice) if gross misconduct is proven and a fair process has been followed.
The decision should be documented, and the employee must receive written confirmation outlining reasons and rights.
Step 6: Offer the Right of Appeal
Employees must be given a genuine opportunity to appeal. The appeal should ideally be heard by someone not previously involved in the case.
How to Prevent Serious Insubordination – Building a Proactive Culture
Preventing insubordination is often more effective than responding after the fact. Employers can reduce risks by:
- Ensuring clear communication of roles, responsibilities, and expectations.
- Providing management training on giving lawful and reasonable instructions, conflict resolution, and early intervention.
- Encouraging a respectful workplace culture, where concerns can be raised openly.
- Documenting instructions and conduct, especially where clarity or evidence may later be required.
- Regularly reviewing disciplinary policies, ensuring they remain legally compliant and reflect organisational needs.
A proactive, transparent culture makes serious insubordination less likely and easier to manage if it does occur.
