Unfair Dismissal Defined: Employer’s Legal Guide

Ending employment is sometimes necessary when you’re running a business. But in Australia, there’s a clear legal line between a fair termination and an unfair dismissal - and getting it wrong can be costly.

This guide breaks down what “unfair dismissal” means under the Fair Work Act 2009 (Cth), who’s protected, how the Fair Work Commission (FWC) decides cases, practical steps to reduce risk, and what to do if a claim lands on your desk. With a fair process and clear documentation, you can stay compliant, protect your brand, and maintain trust with your team.

What Is Unfair Dismissal In Australia?

Under the Fair Work Act, a dismissal is “unfair” if it is harsh, unjust or unreasonable. In practice, this usually means either:

• There wasn’t a valid reason related to conduct or capacity; or
• The process wasn’t fair (for example, the employee wasn’t notified of the concerns or given a genuine chance to respond); or
• The outcome was disproportionate to the issue (for example, summary dismissal for a very minor, first-time breach).

A dismissal can be fair even when difficult, provided there is a valid reason and a fair process. Conversely, even where there is a valid reason (e.g. misconduct), a poor process can still render the dismissal unfair.

Importantly, unfair dismissal protections are part of the national workplace relations system. In most private sector workplaces across Australia, claims are made to the FWC. (There are some limited exceptions for certain state public sector and local government employees.)

Unfair Vs Wrongful Vs Unlawful: What’s The Difference?

• Unfair dismissal: Focuses on fairness under the Fair Work Act - whether the dismissal was harsh, unjust or unreasonable and whether a fair process was followed.
• Wrongful dismissal: A contractual issue - for example, not providing the contractual notice period or breaching an agreed procedure. This is generally pursued in court as a breach of contract claim, not through the FWC’s unfair dismissal jurisdiction.
• Unlawful termination/adverse action: Where someone is dismissed for a prohibited reason (for example, exercising a workplace right, temporary absence due to illness or injury, or discrimination). These sit under different parts of the Fair Work Act and have different processes and remedies.

A single termination can be challenged under more than one framework. Understanding the distinction helps you choose the right process when you need to end employment.

Who Is Protected And When Can A Claim Be Made?

Not every worker can file an unfair dismissal application. Key eligibility rules include:

• Minimum employment period: 6 months for employers with 15 or more employees; 12 months if you’re a small business employer (fewer than 15 employees).
• Award/Agreement coverage or earnings: The employee must be covered by a modern award or enterprise agreement, or if not covered, their annual earnings must be below the high income threshold (assessed at the time of dismissal).
• Casuals: Casual employees must have been employed on a regular and systematic basis and have a reasonable expectation of continuing employment to be eligible.
• Fixed-term employees: The expiry of a truly fixed-term contract generally won’t be a “dismissal” for unfair dismissal purposes.
• Time limit: Applications must be lodged within 21 days after the dismissal takes effect. Extensions are rare and require “exceptional circumstances”.

If you operate a small business, the Small Business Fair Dismissal Code provides a framework for dismissals. Following it carefully can help protect you, but you still need a valid reason and sound process.

What Does The Fair Work Commission Look At?

When the FWC assesses whether a dismissal was harsh, unjust or unreasonable, it considers a range of factors, including (but not limited to):

• Whether there was a valid reason related to conduct or capacity
• Whether the employee was notified of that reason and given a real opportunity to respond
• Any unreasonable refusal by the employer to allow a support person to assist the employee at a discussion about dismissal (note: there’s no strict duty to offer one, but refusing a reasonable request can weigh against you)
• If the dismissal related to unsatisfactory performance, whether the employee had been warned about that performance before the dismissal
• The size and HR resources of your business, which can affect the procedures followed
• Any other relevant matters in the circumstances

Practically, the FWC will expect to see contemporaneous records. If you’ve issued clear warnings, invited responses, and documented your decision-making, you’ll be in a much stronger position.

Common Scenarios The FWC Sees

• Performance concerns: Dismissing without warnings or support often leads to findings of unfairness. A clear performance process and a well-drafted Employment Contract help set expectations from day one.
• Misconduct allegations: A reasonable investigation, a chance to respond, and considering a proportionate outcome are key. Where warranted, consider first whether standing down an employee pending investigation is appropriate while you gather facts.
• Redundancy: To be a “genuine redundancy” (and therefore outside unfair dismissal), you must no longer require the role to be performed by anyone due to operational changes, comply with consultation obligations, and it must not be reasonable to redeploy the employee within your enterprise. If in doubt, seek redundancy advice before making final decisions.

Remedies: What Can The FWC Order?

If an unfair dismissal is established, the FWC can order:

• Reinstatement: The primary remedy, with continuity of employment. This can include orders for restoration of lost pay.
• Compensation: If reinstatement is inappropriate, compensation may be ordered for lost remuneration (not distress or punitive damages). It’s capped at the lesser of 26 weeks’ pay or half the high income threshold immediately before the dismissal.

The FWC doesn’t impose penalties or general damages in an unfair dismissal matter. Separate processes exist for unpaid entitlements or unlawful termination/adverse action claims. That’s why getting your process right up front is so important.

How To Reduce The Risk Of An Unfair Dismissal Claim

Most unfair dismissal risks are preventable. Build your approach around consistency, documentation and fairness.

1) Set Clear Expectations In Writing

• Use a tailored Employment Contract that sets out duties, conduct standards, and how performance issues will be managed.
• Adopt a Workplace Policy or staff handbook covering conduct, performance management, investigations, and disciplinary outcomes.

2) Address Issues Early And Follow A Fair Process

• Identify the issue (performance or conduct), meet with the employee, and confirm the concerns in writing.
• For performance issues, provide clear objectives, support and reasonable time to improve. If things don’t improve, issue written warnings before moving to dismissal.
• For conduct allegations, investigate fairly, consider any response, and evaluate whether a proportionate outcome is warning, final warning or dismissal. When appropriate, issue a structured letter - see practical guidance on show cause letters.
• If you decline a request for a support person at a meeting, document the reasons and ensure the refusal is reasonable in the circumstances.

3) Manage Process Around Notice And Timing

• Confirm whether notice is owed under the Fair Work Act, contract, or policy. If you prefer to end employment immediately, consider payment in lieu of notice (not available for certain serious misconduct).
• Be mindful of the 21-day deadline for any claim. Good records often support an early resolution if a dispute arises.

4) Treat Redundancy As Its Own Process

• Confirm operational reasons, consult as required by any award/enterprise agreement, and consider redeployment options genuinely.
• Calculate severance entitlements correctly. If you’re unsure, check your numbers against your obligations and current thresholds, or review how to calculate your redundancy payment.

5) Prepare Your Documentation Suite

• Keep templates for warnings, meeting invitations, and outcome letters. Many employers rely on an employee termination documents suite to ensure a consistent process.
• For complex matters, get early input from HR or legal - it’s often faster and cheaper than fixing issues later.

Redundancy, Misconduct And Other Tricky Areas

Genuine Redundancy

Unfair dismissal claims are excluded where a dismissal is a “genuine redundancy.” The test has three limbs: operational change means the role is no longer required; required consultation has been carried out; and there is no reasonable redeployment available within the enterprise (or associated entity where applicable). If you restructure and then rehire for substantially the same role shortly after, expect scrutiny.

Serious Misconduct And Summary Dismissal

For serious misconduct (for example, theft, fraud, assault), you can dismiss without notice. However, the FWC still considers whether you acted reasonably overall. A brief but fair investigation, putting key allegations to the employee, and considering their response before making the final decision will help. Where appropriate while investigating, consider standing the employee down to manage risk.

Probation And Minimum Employment Periods

Probation doesn’t automatically remove legal risk. While many employees won’t qualify for unfair dismissal during the minimum employment period, other claims (for example, discrimination or general protections) can still arise. A fair, short process and clear records are still important - our guide to termination during probation explains the key steps.

What To Do If You Receive An Unfair Dismissal Claim

• Move quickly: Note the return date for your employer response. Missing deadlines can limit your options.
• Gather your records: Contracts, policies, meeting notes, warnings, investigation documents, emails, and any relevant witness material.
• Assess risk: Identify strengths and weaknesses in your process. Consider whether early conciliation could resolve it commercially.
• Plan your approach: Many matters resolve at conciliation with agreed outcomes. Where settlement isn’t appropriate, prepare for a conference or hearing with a clear evidentiary bundle.
• Get help if needed: For higher-risk matters, consider support with process and strategy through performance management expertise or advice on redundancy and restructuring if that’s part of the dispute.

Key Takeaways

• Unfair dismissal in Australia is about whether a dismissal was harsh, unjust or unreasonable - both the reason and the process matter.
• Eligibility depends on the minimum employment period, award/agreement coverage or earnings compared to the high income threshold, and specific rules for casual and fixed-term employees.
• The FWC looks for valid reasons, notice of concerns, a real chance to respond, reasonable handling of a support person request, and proportionate outcomes.
• Remedies are reinstatement or capped compensation for lost remuneration - no penalties or general damages in unfair dismissal cases.
• A tailored Employment Contract, robust Workplace Policy, fair warnings, and accurate record-keeping are your best defence.
• Treat redundancy, misconduct and probation with care. Consult early on complex terminations and use structured documents such as an employee termination documents suite to stay consistent.
