Unfair Dismissal: Why “Gross Misconduct” Does Not Always Justify Dismissal
When an employee commits misconduct, employers understandably want to act quickly and firmly. However, even where behaviour is serious, the sanction must still be fair, reasonable and proportionate.
A recent Workplace Relations Commission decision, ADJ-00052619, is a useful reminder that labelling something as “gross misconduct” in a company policy does not automatically make dismissal the correct outcome.
What happened?
In this case, an employee became involved in a heated discussion and referred to his line manager as “useless”. The employer treated the comment as gross misconduct under its company policy.
An investigation and disciplinary process followed. The employee was initially issued with a Final Written Warning.
The employee then exercised his right to appeal. However, following the appeal, the original sanction was overturned and replaced with dismissal.
The WRC found that, although the employer had followed its procedures, the decision to dismiss was disproportionate in the circumstances. In particular, the employee had 16 years’ service, and the misconduct did not justify termination when a lesser sanction was available.
The WRC concluded that a Final Written Warning would have been the more appropriate outcome. The employer was ordered to re-engage the employee, although not on a full reinstatement basis, as the employee had contributed to the events that led to the dispute.
What can employers learn from this?
The key lesson is simple: a fair process is essential, but it is not enough on its own.
Employers also need to show that the final decision was reasonable and proportionate. A dismissal can still be found to be unfair, even where the employer has held meetings, allowed representation, issued letters and followed the steps in its disciplinary procedure.
Before deciding on a sanction, employers should ask:
- How serious was the misconduct?
- Was it a one-off incident or part of a pattern?
- Did the employee accept responsibility or show remorse?
- Has the employee a clean disciplinary record?
- How long has the employee worked for the business?
- Have similar cases been treated in the same way?
- Would a lesser sanction, such as a written warning or final written warning, be sufficient?
Practical steps for employers
When assessing misconduct, employers should:
Assess the facts objectively
Avoid making decisions based on frustration, embarrassment or emotion. The sanction should be based on the evidence and the seriousness of the conduct.
Keep the process impartial
The person investigating should not usually be the same person making the disciplinary decision. Appeal officers should also be independent where possible.
Consider proportionality
Dismissal should generally be reserved for the most serious cases or situations where trust and confidence has been irreparably damaged.
Be consistent
Look at how similar issues have been handled in the past. Inconsistent treatment can weaken the employer’s position.
Take advice before acting
Before dismissing an employee for misconduct, particularly long-serving employees, it is sensible to speak with your HR advisor.
Final point
Misconduct should not be ignored. However, employers must be careful not to jump from misconduct to dismissal without considering whether the sanction is fair in all the circumstances.
A well-run disciplinary process should not just ask, “Did the employee do it?” It should also ask, “What is the appropriate and proportionate response?”
