Unsuccessful Probation Letter: Ending Probation Lawfully in Australia

Ending a probation period is never easy. As a small business owner, you want to move quickly and protect your team culture, but you also need to follow the law and communicate respectfully.

An unsuccessful probation letter helps you do both. It records your decision, explains next steps and reduces the risk of disputes down the track.

In this guide, we’ll walk through what to include, how to deliver the letter, common risks to avoid, and provide a practical unsuccessful probation termination letter sample you can adapt to your business.

What Is An Unsuccessful Probation Letter?

An unsuccessful probation letter is a formal notice to an employee that their employment will end during or at the conclusion of their probation period.

Its purpose is to clearly confirm your decision, set out the effective date, outline any notice or payment in lieu, and explain final pay and return of company property.

For small businesses, this letter is a simple way to document that you’ve made a lawful, considered decision - and that you’ve followed your contractual and Fair Work obligations.

Are You Allowed To Terminate Employment During Probation In Australia?

Generally, yes - if you handle it correctly. Probation is designed to assess a new employee’s suitability. If it’s not working out, you can end the employment during probation - provided you give the correct notice (or pay in lieu), pay entitlements owing, and avoid unlawful reasons.

Key points to remember:

• Minimum notice still applies under the National Employment Standards and your contract (often one week for probationary employees, but check your Employment Contract and any applicable award).
• Unfair dismissal eligibility generally starts after 6 months’ service (12 months for businesses with fewer than 15 employees). However, employees can still bring general protections (adverse action) or discrimination claims at any time.
• Your reason for ending employment must not be unlawful (for example, because of a protected attribute or because the employee exercised a workplace right, like making a complaint or taking paid leave).

If you’re weighing up next steps or process, this overview of terminating employment during probation covers the big picture from an Australian employer’s perspective.

What Should An Unsuccessful Probation Letter Include?

Your letter doesn’t need to be long or argumentative. It just needs to cover the essentials in plain, professional language.

Core Elements To Include

• Employee details: Full name, role title and start date.
• Decision and effective date: Confirm the employment will end and specify the termination date.
• Notice or payment in lieu: State whether you are giving working notice or payment in lieu of notice, and the amount of notice required under the contract or award.
• Brief reason (optional): A short, factual statement that performance or suitability has not met requirements during probation. Avoid detailed commentary or subjective language.
• Final pay and entitlements: Outline what the employee will be paid on termination (outstanding wages, accrued annual leave, superannuation, and any agreed expenses).
• Property and access: Explain the process and timeline for returning company property and removing system access.
• Confidentiality and post-employment obligations: Remind the employee of any ongoing obligations under the contract (e.g. confidentiality, IP ownership, restraint if applicable).
• Point of contact: Provide a contact for questions about final pay and logistics.

Tone And Content Tips

• Be clear, polite and neutral. Avoid debate in writing - the letter is a record of your decision.
• Keep reasons high-level and factual. If you’ve already given feedback during probation, you don’t need to restate everything.
• Double-check dates and amounts. Typos in dates, notice period, or pay calculations are a common trigger for disputes.
• Align with your contract and any applicable award. Your letter should reflect what you’ve promised in the Employment Contract.

Step-By-Step Process To End Probation Lawfully

A solid process reduces risk and protects your business reputation. Here’s a practical workflow many small businesses follow.

1) Check The Contract And Award

Confirm the probation clause, the required notice period, and any specific terms that apply to ending employment. Also check whether an award applies to the role and whether it affects notice, consultation, or final pay. If you need to refresh your obligations, see this overview of employment notice periods.

2) Review Timing Against Service Length

Verify the employee’s start date and continuous service. This helps you understand exposure to potential claims and whether the unfair dismissal threshold has been reached. The factors the Fair Work Commission considers in dismissals are outlined in section 387 of the Fair Work Act - useful context even where unfair dismissal doesn’t yet apply.

3) Plan A Short, Respectful Meeting

Where possible, tell the employee in a meeting before issuing the letter. Keep it brief and respectful. Confirm the decision, hand them the letter, and explain next steps. If remote, use a video or phone call and email the letter immediately after.

4) Provide Notice Or Payment In Lieu

Decide whether the person will work out their notice or whether you’ll give payment in lieu of notice. Payment in lieu is common during probation, especially in small teams, to minimise disruption.

5) Prepare Final Pay

Calculate outstanding wages, accrued annual leave, superannuation and valid expenses. Ensure payroll cut-off dates and transfer details are clear. Provide a written breakdown with the letter or shortly afterwards.

6) Recover Property And Revoke Access

Set a clear timeline for the return of property and secure your systems promptly. Explain exactly what needs to be returned and how to do so, especially if the person is remote.

7) Keep Records

Save the letter, meeting notes, evidence of notice or payment in lieu, and confirmation of returned property. Good records are your best defence if questions arise later.

Common Risks (And How To Avoid Them)

Even during probation, there are legal risks if the process is rushed or reasons are mishandled. Here are the big ones to watch.

Unlawful Reasons

Don’t end employment because of a protected attribute (like race, sex, disability, age), temporary absence for illness or injury, union membership, making a workplace complaint, or other protected workplace rights. These situations can give rise to general protections claims regardless of service length.

Inconsistent Process

When similar situations are handled inconsistently, it can look unfair or discriminatory. Use a consistent internal checklist and a standard letter format. If you’ve previously warned or supported another employee before ending probation, consider whether similar steps are appropriate here.

Over-Explaining Reasons In Writing

Lengthy, subjective performance assessments in the letter can create arguments later. Say just enough to make the communication clear and respectful. If you need a more formal performance process (e.g. you’re not sure you’ll end employment yet), a structured performance plan or a show cause letter is usually a better fit.

Misunderstanding Eligibility For Claims

Unfair dismissal claims generally require a minimum period of employment. But other claims don’t. It helps to understand the Commission’s fairness factors in section 387, and to stick to a clean process either way.

Incorrect Notice Or Final Pay

Underpaying notice, skipping accrued annual leave, or delaying final pay is a common (and avoidable) flashpoint. Double-check your numbers and reflect them accurately in your letter and payroll.

Documents And Policies That Make Probation Easier

With the right documents in place from day one, probation decisions are clearer and lower-risk.

• Employment Contract: Sets probation length, notice requirements, and post-employment obligations. A clear contract is the foundation for a smooth probation process.
• Performance Management Process: A simple, practical framework for feedback and expectations. If you foresee performance issues rather than a clean end to probation, this helps you manage risk and support improvement.
• Workplace Policies or Staff Handbook: Outline conduct standards, leave, technology use and complaint processes. Policies give employees clarity, making probation assessments more objective.
• Employee Termination Documents: A suite of compliant letters and checklists helps you action decisions cleanly and consistently.

If you’re building or updating your hiring toolkit, consider locking in a strong Employment Contract template that clearly sets expectations about probation, confidentiality, IP and notice.

Frequently Asked Questions About Unsuccessful Probation Letters

Do I Have To Give A Reason In The Letter?

It’s not legally required to give a detailed reason during probation, but a short, neutral statement about suitability is common. Avoid lengthy justifications or criticism in writing. Save detailed feedback for earlier in probation, and keep the letter as the formal confirmation.

How Much Notice Do I Need To Give?

Check the contract and any applicable award. It’s often one week during probation, but this can vary. If you don’t want the employee to work out their notice, you can generally make a payment in lieu of notice and end the employment immediately.

Can A Probationary Employee Claim Unfair Dismissal?

Usually not until they’ve completed the minimum employment period (6 months, or 12 months for small businesses under 15 employees). But they can bring other claims (like general protections or discrimination) regardless of service length, so your reason and process still matter.

Should I Meet With The Employee Or Just Send The Letter?

It’s best practice to tell the person in a brief meeting (in-person or video call), then provide the letter straight after. This is respectful and reduces confusion about logistics, pay and next steps.

Putting It Together: A Practical Checklist

Before you issue your letter, run through this quick checklist:

• Review the Employment Contract and any applicable award to confirm probation terms and notice.
• Confirm service length and consider claim risks (including the factors in section 387).
• Prepare final pay calculations (wages, accrued annual leave, super, expenses).
• Decide on working notice vs. payment in lieu.
• Draft the letter using the sample above, tailored to your business and contract.
• Plan a short meeting, then send the letter immediately after.
• Recover company property and revoke access on a clear timeline.
• File records in your HR system or personnel file.

Key Takeaways

• An unsuccessful probation letter is a concise, respectful record that employment is ending during probation and sets out notice, final pay and next steps.
• Even during probation, you must give correct notice and avoid unlawful reasons - claims like discrimination or adverse action can arise at any time.
• Keep the letter short and neutral; provide detailed feedback earlier, not in the termination letter itself.
• Use a consistent process: check the contract and award, meet with the employee, issue the letter, pay entitlements, and secure property and access.
• Having the right documents (such as an Employment Contract and Employee Termination Documents) makes probation decisions clearer and lower-risk.
• For context on process and risks, refer to guidance on terminating employment during probation and the fairness factors in section 387.
