Can an Employer Terminate Employment for Serious Misconduct?

What Is Serious Misconduct?

"Serious misconduct" is a legal term, not just a strong adjective. Under the Fair Work Regulations 2009 (Cth) it includes conduct that is wilful or deliberate and inconsistent with the continuation of the employment contract, and conduct that causes serious and imminent risk to the health and safety of a person, or to the reputation, viability or profitability of the employer's business.

Crucially, serious misconduct must be more than poor performance, isolated error or a lapse in judgment. It describes conduct that fundamentally undermines the employment relationship — the kind of breach that, if proved, would entitle the employer to end the contract without notice.

Examples of Serious Misconduct

The Regulations and the case law recognise a range of conduct that may amount to serious misconduct depending on the surrounding circumstances. Common categories include:

Theft

Taking cash, stock, equipment or personal property belonging to the employer, clients or other staff is the archetypal example. Even small thefts can justify dismissal where they involve a serious breach of trust — for example, a cashier under-ringing a sale, or a warehouse worker taking inventory home.

Fraud

Falsifying timesheets, expense claims, customer invoices, qualifications or sales records can all amount to serious misconduct. Fraud cases turn heavily on intention and the documentary evidence — careful investigation is essential before acting.

Violence and Threats

Physical assault, fighting, throwing objects, or credible threats of violence will usually justify summary dismissal, particularly where other staff or customers were exposed to risk. The employer's response should be calibrated to the actual conduct, not to rumour.

Harassment and Bullying

Serious sexual harassment, racial abuse or sustained bullying can amount to serious misconduct. A single incident may be enough where the conduct is egregious; repeated lower-level conduct may also justify dismissal once warnings have been given and ignored.

Breaches of Safety Requirements

Deliberately bypassing safety procedures, operating equipment while affected by alcohol or drugs, or ignoring critical safety instructions can amount to serious misconduct because of the risk to the worker and others. Victorian OHS obligations make a robust response particularly important.

Misuse of Confidential Information

Taking client lists, intellectual property, pricing data or commercially sensitive information — particularly when moving to a competitor — can justify summary dismissal. Forensic evidence (email exports, USB activity, cloud uploads) often plays a central role.

Social Media Misconduct

Posts that disclose confidential information, harass colleagues, disparage the employer or breach a clear social media policy can all support serious-misconduct findings. The Fair Work Commission has consistently held that "out of hours" conduct can ground dismissal where it has a relevant connection to the employment.

When Summary Dismissal May Be Lawful

Where serious misconduct is established, the employer may terminate without notice or payment in lieu. But "may" is doing a lot of work in that sentence. The Fair Work Commission will ask:

• Did the conduct actually occur?
• Was it serious enough — assessed objectively — to justify dismissal without notice?
• Was the employee notified of the allegation and given a genuine opportunity to respond?
• Were any mitigating circumstances considered before the decision was made?
• Was the response proportionate, taking into account length of service, prior record and the nature of the role?

A "yes" to the conduct question is necessary but not sufficient. Many employers lose unfair dismissal cases even though the underlying allegation is proved, because the process fell short.

Why Procedural Fairness Still Matters

Procedural fairness is not a technicality. It is the mechanism that turns a suspicion into a defensible decision. The minimum requirements are well established:

• clearly identify the allegation, in writing, before the meeting;
• give the employee enough time and information to respond meaningfully;
• allow a support person to attend any meeting where dismissal is a possible outcome;
• genuinely consider the employee's response before making the decision; and
• document each step, including the reasoning that led to the outcome.

Workplace Investigations

In all but the simplest cases, a proper workplace investigation should precede a serious-misconduct dismissal. An investigation usually involves:

• defining the allegations precisely;
• identifying and securing relevant evidence (CCTV, timesheets, emails, system logs, financial records);
• interviewing the complainant, the respondent and any relevant witnesses;
• giving the respondent a written summary of the allegations and evidence; and
• producing a report that addresses each allegation on the balance of probabilities.

For sensitive matters — sexual harassment, allegations against a senior manager, or matters where the employer cannot be seen as neutral — an external investigator is often the safer option.

Common Employer Mistakes

The recurring missteps the Fair Work Commission sees in serious-misconduct cases include:

• Pre-judging the outcome. Drafting the termination letter before the meeting, then going through the motions.
• Vague allegations. Telling the employee they have "behaved unprofessionally" rather than specifying the conduct, date and witnesses.
• Ambush meetings. Calling the employee into a meeting with no notice and demanding an immediate response.
• Denying a support person. Refusing or discouraging a support person where dismissal is a possible outcome.
• Ignoring mitigating factors. Failing to consider length of service, clean record, contrition, health issues or personal circumstances.
• Inconsistent treatment. Dismissing one employee for conduct that has previously attracted a warning for another.
• Poor documentation. No file note, no show-cause letter, no record of the response — making it almost impossible to defend the decision later.

Common Employee Misconceptions

Employees sometimes misunderstand the position in equally important ways:

• That a long period of unblemished service immunises them from dismissal for a serious incident — it does not, although it is a relevant mitigating factor.
• That "out of hours" conduct can never lead to dismissal. It can, where there is a sufficient connection to the employment.
• That the employer must "prove it beyond reasonable doubt". The civil standard — balance of probabilities — applies.
• That resigning during an investigation prevents an unfair-dismissal claim. In some circumstances a constructive dismissal claim can still follow.

Unfair Dismissal Risks

Eligible employees can bring an unfair dismissal claim in the Fair Work Commission within 21 days of dismissal. The Commission will look at whether there was a valid reason, whether the employee was notified of the reason, whether they were given an opportunity to respond, whether a support person was permitted, and whether the size of the employer and the absence of HR expertise affected the process.

Remedies include reinstatement and compensation of up to six months' pay (capped at the high-income threshold). Even where reinstatement is not ordered, the indirect costs — legal fees, management time, settlement payments, reputational damage — are routinely significant.

Adverse action claims under the general protections provisions carry no compensation cap and can be brought in the Federal Circuit and Family Court of Australia, making them a separate and serious risk where the dismissal might be characterised as a response to a workplace right.

Practical Steps Employers Should Take Before Dismissal

1. Pause and define. Resist the instinct to act immediately. Define the allegation precisely before any meeting.
2. Secure the evidence. Preserve CCTV, system logs, financial records and any physical evidence before they can be lost or altered.
3. Consider suspension on pay. Where there is a risk to safety, evidence or other staff, suspend in writing as a neutral step pending investigation.
4. Investigate properly. Either internally by a person genuinely independent of the dispute, or externally for sensitive matters.
5. Issue a show-cause letter. Set out the allegations, attach the key evidence, advise that dismissal is a possible outcome, offer a support person, and give reasonable time to respond.
6. Hold the meeting and listen. Take the response seriously and document it. Do not pre-write the decision.
7. Decide and explain. Make the decision after considering the response, and explain the reasons in writing.
8. Final pay and entitlements. Calculate correctly — summary dismissal removes notice but not accrued leave or any contractual entitlements that survive termination.
9. Diarise the 21-day window. Anticipate an unfair dismissal application and brief your lawyer early if one is likely.
