When a team member hands you a medical certificate, you’re generally entitled to accept it at face value. But what if something doesn’t add up - dates are inconsistent, the clinic can’t be found, or you discover evidence the certificate was altered?
Submitting a false medical certificate can be a serious workplace issue. Handled poorly, it can create legal risk for your business. Handled well, it can reinforce your standards while meeting your Fair Work obligations and privacy requirements.
In this guide, we’ll unpack what a “false medical certificate” looks like, when it may amount to serious misconduct, how to investigate fairly, and the range of lawful disciplinary outcomes available to you. We’ll also share practical steps to prevent problems with clear policies and contracts.
What Is A “False Medical Certificate” In Australia?
A medical certificate is a document from a registered health practitioner that states an employee was unfit for work for a specified period. Most of the time, certificates are entirely legitimate - and the law expects you to treat them seriously.
A certificate may be “false” if, for example:
- It was fabricated or altered by the employee (forged signature or clinic logo, changed dates, edited details).
- It was issued by a person who is not a registered health practitioner.
- It was obtained through dishonest means (e.g. asking a practitioner to backdate for days the employee wasn’t actually sick).
Keep in mind that not every odd-looking certificate is fraudulent. There are differences in clinic formats, typos happen, and practitioners can choose how much detail they include. Your job is to treat concerns seriously, but approach them with an open mind and a fair process.
Is Submitting A False Medical Certificate Serious Misconduct?
Dishonesty that undermines trust - including fraud and forgery - can amount to serious misconduct under the Fair Work framework. In many cases, knowingly submitting a false medical certificate falls into that category because it’s an attempt to obtain paid leave or avoid work through dishonesty.
However, “serious misconduct” is a high bar. The label is not automatic just because a document looks suspicious. You must establish facts through a reasonable investigation and consider the context, including the employee’s explanation, their length of service, any prior warnings, and whether the conduct was intentional.
There’s also potential criminal law risk for the person who creates or alters a document to deceive (forgery or fraud). Employers don’t decide criminal liability, but your internal process should recognise the seriousness and follow a careful, procedurally fair path before any disciplinary decision.
How Should Employers Investigate A Suspected False Certificate?
When concerns arise, a fair, consistent and well-documented process is your best protection. A solid approach generally includes the following steps.
1) Preserve Evidence And Consider Temporary Arrangements
Secure the certificate and any related records (rosters, timesheets, emails, messaging). If you’re worried about workplace risk or interference with evidence, consider a non-punitive suspension on full pay or a temporary reassignment while you investigate. In some circumstances, standing down an employee pending investigation is appropriate, but ensure you have a lawful basis and follow your contract and policies.
2) Clarify What You’re Checking
Identify exactly what appears questionable (e.g. clinic doesn’t exist, dates don’t match known facts, text looks edited). Keep your inquiry focused and proportionate to the concern. You’re verifying authenticity, not performing a medical assessment of the employee’s condition.
3) Check Your Internal Policies And Contract
Your Employment Agreement and leave policies should set expectations about providing evidence and cooperating with reasonable inquiries. If your Employment Contract and policy framework are clear, it’s easier to explain what you’re asking for and why.
4) Request Information Lawfully
You can require evidence that would satisfy a reasonable person that the employee was unfit for work. That typically means a medical certificate or statutory declaration. You can ask for clarification about the certificate (e.g. practitioner’s provider number or clinic details), but avoid pressuring the employee to disclose diagnosis or sensitive health information.
As a refresher on the boundaries, read up on when employers can ask for medical certificates. If the employee has been off for an extended period or after an injury, there are also limits and obligations around medical clearance to return to work.
5) Seek The Employee’s Response
Procedural fairness is key. Put the concern to the employee in writing with enough detail to allow a meaningful response. Give them a reasonable time to reply and consider letting them bring a support person to any meeting.
This is a good time to issue a careful letter that sets out the allegations and invites a response - often called a show cause letter. Keep the tone neutral and stick to the facts.
6) Keep Privacy Front Of Mind
Don’t contact a medical practice seeking personal health information without the employee’s informed consent. If you need to verify that a certificate was issued (date and authenticity only), ask the employee for written consent first. They have rights around sensitive health information, and there are limits on employer access - see more about employee medical records and employer access.
7) Make A Decision And Document It
After considering all information, decide whether the allegation is substantiated on the balance of probabilities. If so, determine an appropriate outcome. If not, close the matter and consider whether any guidance or policy reminders are still warranted. Record your reasoning and the evidence you relied on.
What Disciplinary Action Or “Punishment” Is Lawful?
If you find an employee intentionally submitted a false medical certificate, the disciplinary response should be proportionate, consistent with past practice, and aligned with your policies and contract. Here are common options - think of them as a spectrum.
Informal Counseling Or Training
For low-level issues (e.g. careless handling rather than dishonesty), a coaching conversation or written reminder about policy requirements may be enough. This can be paired with refreshed training on acceptable evidence, leave notice obligations and workplace honesty standards.
Formal Warning
A written warning sets out what occurred, why it breaches policy, the expected standard going forward, and the consequences of further misconduct. A warning is often appropriate if there are mitigating factors (e.g. confusion about evidence rules) and trust can be rebuilt.
Final Warning
A final written warning may be suitable where the conduct is serious but termination would be disproportionate in the circumstances (for example, genuine remorse and a previously clean record).
Termination Of Employment
If the conduct amounts to serious misconduct - such as deliberate fraud or falsifying a document - termination may be justified. Whether you dismiss with notice or summarily (without notice) depends on the severity and your findings.
To reduce the risk of unfair dismissal claims, follow a fair process, give the employee an opportunity to respond, consider their response with an open mind, and base the decision on evidence. A structured performance management and termination process can help you stay on track.
Can You Deduct Pay Or Withhold Wages?
Wage deductions are tightly regulated. Even if an employee submitted a false certificate, you generally can’t unilaterally deduct pay unless permitted by law, an award, or an upfront written agreement that meets Fair Work requirements. Get familiar with the rules around withholding pay from employees before you consider any deduction.
Should You Report The Matter Externally?
If you believe a medical practitioner has engaged in wrongdoing, you may consider reporting concerns to their clinic or the relevant regulator. If you believe a potential crime has occurred (forgery/fraud), you can consider a police report. Get legal advice before escalating - this helps you manage defamation, privacy, and employment risks.
Can You Contact The Doctor Or Verify A Certificate Directly?
Employers often ask whether they can call a clinic to verify a certificate. You can verify authenticity in a limited way, but proceed carefully.
- Seek the employee’s written consent before contacting a clinic. Make it clear you’re only seeking to confirm whether the certificate was issued and by whom (not medical details).
- Avoid asking for diagnosis or clinical notes - that’s sensitive health information and generally out of bounds without explicit consent and a clear legal basis.
- If consent isn’t given, decide whether you have enough evidence from other sources to proceed (e.g. inconsistencies, document analysis, prior admissions). Be cautious about drawing adverse inferences solely from refusal - context matters.
- If the issue is not just authenticity but fitness for work, consider a tailored, independent assessment pathway with proper consent and a specific list of job-related questions. For prolonged absences or return-to-work situations, employers may seek medical clearance that focuses on capacity and reasonable adjustments, not diagnosis.
Whatever you do, ensure the scope of your inquiries is proportionate to the issue and aligns with your policies. Overreach can create privacy complaints and undermine trust.
Preventing Problems: Policies, Contracts And Training
The best way to manage risk is to set clear expectations up front and apply them consistently. A strong framework also gives you confidence that any disciplinary action will be backed by documented standards.
Set Clear Evidence Rules For Personal Leave
Your policies should explain when evidence is required for personal/carer’s leave (for example, for any absence of more than a day, or when requested by the business), what type of evidence is acceptable, how and when to submit it, and the consequences of providing false or misleading information. Reference how you’ll handle verification steps and privacy.
Align Your Contracts And Policies
Make sure your Employment Agreements point to your policies and clearly state that dishonesty and falsification of records may constitute serious misconduct. Having robust documents in place - like an Employment Contract synced with a Staff Handbook and a clear Workplace Policy suite - makes expectations transparent and defensible.
Train Managers On Fair Process
Equip managers to spot red flags without jumping to conclusions. Train them on how to request evidence, handle sensitive information, issue a show cause letter, and apply consistent, proportionate outcomes.
Use A Consistent Investigation And Decision Template
Consistency reduces claims of bias. Adopt a simple template for investigations: issue identification, evidence list, employee response, findings, outcome options considered, final decision with reasons. If issues escalate, a clean paper trail helps a lot.
Plan For Edge Cases
Sometimes the dispute isn’t about authenticity but about adequate evidence, timing, or repeated short-notice absences. Your policies should address when you can ask for evidence, including for short absences where reasonable, and how you’ll respond to non-compliance. That clarity prevents confusion and supports reasonable directions to staff.
Have A Fair “Second Chance” Pathway
Not every misstep warrants dismissal. Set out how warnings work and how employees can rebuild trust (e.g. compliance checks for a period, refresher training, closer oversight). Consistent second-chance processes show you’re fair while still upholding standards.
Key Takeaways
- Submitting a false medical certificate can amount to serious misconduct, but you must establish facts through a fair, evidence-based process before deciding on any “punishment.”
- Follow a clear investigation pathway: preserve evidence, check your contract and policies, request reasonable information, seek the employee’s response, and document your decision.
- Disciplinary outcomes should be proportionate - options range from counseling and warnings through to termination for deliberate dishonesty, supported by a fair process.
- Be careful with privacy: verify authenticity within limits, seek the employee’s consent, and avoid requesting sensitive health details without a lawful basis.
- Strong foundations reduce risk: align your Employment Contract, policy suite and training so expectations about evidence and leave are transparent and consistently applied.
- Before making deductions or withholding pay, check the strict rules that apply to wage deductions and ensure any step is lawful and documented.
