Unfair Dismissal Small Business Exemption: What Employers Need To Know In Australia

If you run a small business, managing staff issues can feel personal, time-consuming and high-stakes. When performance slips, misconduct happens, or the business simply can’t sustain a role, you might need to end someone’s employment - but you also want to avoid an unfair dismissal claim.

The good news is that Australian workplace law recognises the realities of small business. In some cases, the unfair dismissal small business exemption can help protect eligible employers from unfair dismissal claims if the dismissal is handled in line with the rules.

In this guide, we’ll walk you through what the exemption is, when it applies, what the Small Business Fair Dismissal Code requires, and the practical steps you should follow to reduce your risk (without getting bogged down in legal jargon).

What Is The Unfair Dismissal Small Business Exemption?

The unfair dismissal small business exemption is a protection available to eligible small business employers against unfair dismissal claims, where the dismissal is consistent with the Small Business Fair Dismissal Code.

In plain English: if you are a small business employer and you follow the Code when dismissing an employee, you have a much stronger basis to defend an unfair dismissal claim. The Fair Work Commission will still look at the facts, including whether the Code was complied with.

This matters because unfair dismissal claims can be distracting and costly - not just financially, but in management time and stress. The exemption is designed to give small businesses a clearer, more practical framework for ending employment fairly.

Unfair Dismissal vs “General Protections” (They’re Not The Same)

A key trap for employers is assuming the small business exemption stops all employment claims. It doesn’t.

• Unfair dismissal focuses on whether the dismissal was “harsh, unjust or unreasonable”.
• General protections (also called “adverse action”) claims focus on whether the employee was dismissed for a prohibited reason (for example, because they exercised a workplace right, made a complaint, or due to discrimination).

Even if you can rely on the unfair dismissal small business exemption, you can still face other claims if the dismissal is for the wrong reasons or handled in a way that breaches other laws.

Do You Qualify As A “Small Business Employer”?

To rely on the unfair dismissal small business exemption, you first need to qualify as a small business employer at the time of the dismissal.

Generally, this means you employ fewer than 15 employees.

How Is The 15-Employee Threshold Calculated?

The headcount is usually based on a simple “number of employees” calculation (not full-time equivalent). In practice, this often means:

• Full-time and part-time employees are counted.
• Casual employees are counted if they are employed on a regular and systematic basis.
• Associated entities (for example, related companies) may also be relevant when counting employees in some circumstances.

If you’re sitting close to the 15-employee line, it’s worth getting advice early. Whether you qualify can be disputed, and details like “regular and systematic” casual work and whether another entity is an “associated entity” can be very fact-specific.

Do Employees Need A Minimum Period Of Service?

Yes - and the qualifying period is different for small businesses.

For unfair dismissal claims, employees must complete a minimum employment period before they can make a claim. For small business employers, that minimum period is typically 12 months (as opposed to 6 months for larger employers).

That doesn’t mean you can ignore process during someone’s first year. It just means unfair dismissal is less likely to be the claim pathway. You should still document issues and act reasonably, particularly because other claims can still arise.

When you’re ending employment early, it’s also important to think about the legal risks and best practice around probation and early termination, including your termination process during probation.

What Is The Small Business Fair Dismissal Code (And Why It Matters)?

The Small Business Fair Dismissal Code is essentially your roadmap. If you follow it, you’re in a much stronger position to rely on the unfair dismissal small business exemption in the event of an unfair dismissal claim.

The Code recognises two broad dismissal pathways:

• Summary dismissal (no notice) for serious misconduct, and
• Dismissal with notice for performance or conduct issues that are not “serious misconduct”.

Let’s break down what this usually looks like in a real workplace.

1) Summary Dismissal (Serious Misconduct)

You may be able to dismiss an employee immediately (or very quickly) if you have reasonable grounds to believe the employee has engaged in serious misconduct.

Common examples can include things like theft, fraud, violence, serious safety breaches, or being intoxicated at work in a way that creates significant risk.

Important: You still need a reasonable basis for your belief. In most cases, that means you should take some steps to confirm what happened before you dismiss, even if the decision needs to be made quickly.

If the situation is serious but unclear, you might consider a short investigation process first. Depending on the circumstances, you may look at options like temporarily standing the employee down while you investigate (done carefully and lawfully): standing down pending investigation.

2) Dismissal With Notice (Performance Or Misconduct)

Where the issue is performance (for example, not meeting targets, repeated mistakes, poor customer service) or less serious misconduct (for example, repeated lateness), the Code expects a fair and practical process.

As a small business employer, you don’t need a “perfect” HR process - but you do need to show that:

• the employee was told there was a problem,
• they were warned that their job could be at risk if there wasn’t improvement, and
• they were given a reasonable chance to improve.

If you’re thinking, “How many warnings do I actually need to give?” - it depends on the circumstances, but it’s a common question. Having a consistent approach (and written records) will help, and you may find it useful to review practical guidance on how many warnings before dismissal.

How To Apply The Exemption In Practice (A Step-By-Step Approach)

Knowing the Code exists is one thing. Applying it consistently - especially when you’re busy running the business - is another.

Here’s a practical framework you can use before you dismiss an employee, to strengthen your position under the unfair dismissal small business exemption.

Step 1: Get Clear On The Reason For Dismissal

Start by identifying the real reason you’re considering dismissal. Ask yourself:

• Is this a performance issue, a conduct issue, or serious misconduct?
• Is this really about the employee’s behaviour, or is the role genuinely no longer required (which might be a redundancy)?
• Do you have documents, messages, witness notes, sales reports, time records or other evidence to support the issue?

This step is crucial. If the reason shifts over time, or isn’t documented, you can end up on the back foot if a dispute arises later.

Step 2: Put Concerns To The Employee (Clearly And Calmly)

You generally want to have a direct conversation with the employee about the concerns.

Keep it factual, not personal. Explain:

• what the issue is,
• what standard you expect, and
• what needs to change (with examples where possible).

In higher-risk situations, you may also want to set this out in writing as part of a formal process. Depending on the circumstances, a structured letter can help you present the issue fairly and consistently - for example, using a show cause letter approach where appropriate.

Step 3: Provide A Reasonable Chance To Improve

What’s “reasonable” depends on the job, the seniority, and the nature of the problem.

For example:

• If it’s a skills gap, the employee may need training and time to implement feedback.
• If it’s repeated lateness, improvement can often be shown quickly - but you should still be clear about expectations.
• If it’s a serious safety issue, your timeframe might be very short because the risk is higher.

Setting a review period (for example, 2–4 weeks) and checking in during that period can help show you acted reasonably.

Step 4: Warn Them Their Employment Is At Risk

This is the step many small businesses skip, often because it feels uncomfortable.

But a clear warning is one of the most important parts of relying on the unfair dismissal small business exemption for performance or misconduct matters. Ideally, your warning should:

• be in writing (even an email can help),
• state that the employee’s employment may be terminated if there is no improvement, and
• set a timeframe for the employee to demonstrate improvement.

It doesn’t need to be aggressive or legalistic. It just needs to be clear.

Step 5: Make A Decision And Confirm The Outcome Properly

If there is no improvement (or the issue repeats), you can decide to end employment.

At that point, it’s essential to get the basics right:

• Confirm whether you are giving notice or payment in lieu of notice.
• Calculate final pay correctly (including any unused annual leave, and other entitlements where applicable).
• Give the employee a termination letter that confirms the end date and reason (at a high level).

If you’re paying out notice rather than having the employee work it, make sure you understand how payment in lieu of notice works in practice.

It’s also worth double-checking minimum notice requirements based on the employee’s length of service. Many employers keep a simple reference guide on hand for calculating notice periods so termination decisions don’t become rushed or inconsistent.

Common Small Business Mistakes That Can Undermine The Exemption

Even when the reason for dismissal is legitimate, small missteps can increase the risk of a dispute.

Here are some of the most common issues we see small business employers run into when relying on the unfair dismissal small business exemption.

Not Keeping Written Records

Busy workplaces move fast - but memories fade even faster.

Whenever you have a performance or conduct conversation, keep a simple record (date, what was discussed, what the expectations are, and what support was offered). This doesn’t need to be complicated.

Calling A Redundancy A “Dismissal” (Or Vice Versa)

If the role is no longer required due to operational changes, the situation may be a redundancy rather than a performance-based termination.

This matters because redundancy has its own legal requirements, including consultation obligations in many cases, and possible redundancy pay depending on eligibility.

If you’re planning a restructure or role reduction, it can help to sanity-check what you might owe using a redundancy calculator as a starting point - and then confirm the legal position for your specific business.

Terminating In The Heat Of The Moment

We get it - sometimes an incident happens and you want to act quickly.

But if it isn’t clear-cut serious misconduct, you should generally slow down, gather facts, and follow a simple process. A rushed dismissal can create unnecessary legal risk, even when the underlying concern is valid.

Inconsistent Treatment Between Employees

If two employees commit similar misconduct, but one is dismissed and the other is “given a pass”, this can create a fairness issue (and can also fuel other types of claims).

Consistency is one of your best risk-management tools. Clear policies and templates can help you stay consistent even when you’re under pressure.

Assuming The Exemption Is Automatic

The exemption is not a free pass. It is tied to following the Code and acting reasonably, and it operates as a defence to unfair dismissal only.

If you’re unsure whether your process lines up with the Code, it’s usually far cheaper to get advice early than to deal with a dispute later.

Key Takeaways

• The unfair dismissal small business exemption can protect eligible small business employers from unfair dismissal claims, but only if the dismissal follows the Small Business Fair Dismissal Code.
• You generally qualify as a small business employer if you employ fewer than 15 employees (including regular and systematic casuals in many cases, and sometimes taking associated entities into account).
• For serious misconduct, summary dismissal may be available, but you still need reasonable grounds and should gather facts before acting.
• For performance or less serious misconduct, the safest approach is: raise concerns, give clear expectations, provide a reasonable chance to improve, and warn that employment is at risk.
• Good record-keeping, consistent treatment, and correct final pay/notice handling are practical steps that significantly reduce legal risk.
• If the issue is really operational (not performance), you may be dealing with a redundancy - and different rules and payments can apply.
