Managing Excessive Employee Sick Leave: A Legal Guide for Australian Businesses

It is 7:45 AM on a Tuesday, and your phone buzzes with yet another text message from Sarah, your lead inventory coordinator. “Hi, so sorry, feeling terrible today and won’t make my shift. Doctor certificate attached.” This is the fourth time this month, and looking back at the payroll records, Sarah has taken 18 sick days over the last five months, long after exhausting her accrued paid personal leave. You are starting to notice a pattern of absences on Tuesdays following long weekends, your other employees are growing resentful of the mounting workload, and you are dreading having to sit down and address this with her. You want to support her if she is genuinely unwell, but the operational strain on your small business is becoming unsustainable.

What is actually at stake here is not just lost productivity or roster headaches, but massive financial exposure and legal risk under the Fair Work Act 2009 (Cth). Rushing to terminate or discipline an employee who is frequently absent due to illness can expose your business to a general protections claim involving dismissal, a claim under federal and state anti-discrimination laws, or an unfair dismissal application. A single misstep can result in a Fair Work Commission (FWC) application, which must be lodged within 21 days after a dismissal takes effect. This can lead to costly compensation orders, court-imposed penalties, or forced reinstatement, which can severely disrupt a small-to-medium enterprise.

Additionally, there is significant evidentiary risk. If your business cannot prove that it requested appropriate medical evidence or that it followed a rigorous, legally compliant process before taking adverse action, courts and tribunals are highly likely to resolve any ambiguity in favour of the employee. Balancing your duty to accommodate a genuinely unwell worker with your operational need for a reliable workforce requires navigating a complex intersection of the National Employment Standards (NES), temporary absence protections under reg 3.01 of the Fair Work Regulations 2009 (Cth), and work health and safety duties.

A Step-by-Step Remediation Strategy

1. Calculate leave balances and verify statutory protections

Before initiating any formal conversation, you must have an absolute grasp of the employee's leave entitlements under the law. Paid personal/carer's leave is a core entitlement under the National Employment Standards (NES), set out in s 96 of the Fair Work Act 2009 (Cth). A full-time employee is entitled to 10 days of paid personal/carer's leave for each year of service, which accrues progressively and accumulates from year to year. Part-time employees accrue a pro-rata amount, while casuals do not receive paid sick leave but can access unpaid carer's leave.

The first critical protection you must analyze is the temporary absence protection under s 352 of the Fair Work Act 2009 (Cth), which prohibits dismissing an employee because they are temporarily absent due to illness or injury. However, under reg 3.01 of the Fair Work Regulations 2009 (Cth), an illness or injury ceases to be a protected "temporary absence" if:

• The absence extends for more than 3 consecutive months, or the total absences within a 12-month period exceed 3 months; and
• The employee is not on paid personal/carer's leave for the entire duration of the absence.

This means if an employee has substantial accrued paid leave and remains on paid personal leave, they are protected under s 352 even if it exceeds 3 months. If they exhaust their paid leave and transition to unpaid leave, and their absences exceed 3 months, they are no longer protected under s 352. Note they may still have protections under unfair dismissal or anti-discrimination laws.

Before taking action, compile a detailed record including:

• The exact amount of paid personal/carer's leave accrued and taken by the employee.
• The exact dates of all absences over the last 12 months, categorized into paid, unpaid, and unauthorized leave.
• Whether the absence is covered by state-based workers' compensation schemes, which offer longer protection periods (often 6 to 12 months depending on the state).
• Whether the employee has completed the minimum employment period (6 months, or 12 months for small businesses with fewer than 15 employees) to access unfair dismissal claims.

2. Request and scrutinise medical evidence systematically

You are legally entitled to request evidence for any period of personal leave, even for a single day, if the request is reasonable. Under the NES, an employee must give notice of the absence as soon as practicable and, if requested, provide evidence that would satisfy a reasonable person that the leave is taken because they are unfit for work.

The standard form of evidence is a medical certificate issued by a registered medical practitioner or a statutory declaration. While you must respect the doctor's assessment, you should systematically review the evidence provided.

When evaluating medical evidence, you should:

• Verify that the certificate is signed by a registered practitioner and specifies the dates of the incapacity.
• Check if the certificate is backdated; frequent backdating is a red flag that warrants closer attention.
• Avoid attempting to diagnose the employee or questioning the clinical judgment of their doctor, which can trigger discrimination claims.
• Ensure that requests for medical evidence are made consistently across your workforce, rather than targeting a single employee.
• Keep all medical certificates securely and confidentially, in accordance with Australian privacy principles.

3. Conduct a structured, supportive consultation meeting

If frequent short-term absences cause operational disruption, schedule a formal consultation meeting. Frame this as a supportive discussion focused on the employee's well-being, the operational impact, and how the business can help.

During this meeting, be mindful of the Disability Discrimination Act 1992 (Cth) and state equivalents like the Anti-Discrimination Act 1977 (NSW). If the employee suffers from a chronic physical or mental condition, they are protected from discrimination. You must explore whether reasonable adjustments can be made to help them perform their role before considering termination.

Your consultation meeting should focus on:

• The operational reality: Show a factual, objective summary of the absences and explain how they impact rosters and colleagues.
• Workplace adjustments: Discuss potential adjustments, such as modified duties, temporary part-time hours, or flexible working arrangements under the NES.
• Offering support: Direct them to your Employee Assistance Program (EAP) or advise them to discuss workplace modifications with their doctor.
• Documenting outcomes: Put any agreed adjustments in writing, send a copy to the employee, and set a review date.
• The support person: Invite the employee in writing to bring a support person to the meeting, as failing to do so is a common procedural error the FWC heavily scrutinises.

4. Implement clear notification and communication protocols

While you cannot control when an employee falls ill, you can manage how they communicate their absence. Establish clear, reasonable workplace policies governing the notification process. A failure to follow these policies can be treated as a legitimate performance or disciplinary issue.

Your business's notification policy should clearly outline:

• The timing of notice: Employees must notify their manager as soon as reasonably practicable, ideally before their shift commences.
• The method of notice: Specify that notice must be given via a direct phone call rather than an SMS or email, unless exceptional circumstances prevent it.
• The required information: The employee should state the general nature of their absence and a realistic estimate of their return date.
• The consequences of non-compliance: Clearly state that failing to notify the business in accordance with the policy may result in formal disciplinary action, independent of the illness itself.

5. Conduct an inherent requirements assessment before making a final decision

If an employee has been away for more than 3 consecutive months (or more than 3 months in a 12-month period), has exhausted their accrued paid personal leave, and is unable to return, they are no longer protected under s 352 of the Fair Work Act 2009 (Cth). However, you cannot dismiss them immediately.

To defend against an unfair dismissal or discrimination claim, you must demonstrate that the employee is unable to perform the "inherent requirements" of their role, and that there are no reasonable adjustments that would allow them to do so in the foreseeable future.

Before arriving at a termination decision, you must take the following steps:

• Request a formal medical report: Ask the employee's treating doctor or direct them to an independent medical examination to answer specific questions regarding their capacity to perform the core duties of their role.
• Consider alternative roles: Assess whether there are vacant alternative roles within the business that the employee is fit to perform.
• Issue a formal show-cause letter: If medical evidence confirms they cannot perform the inherent requirements of their role, draft a formal letter outlining that you are considering termination and inviting their response.
• Provide a reasonable opportunity to respond: Give the employee at least 3 to 5 business days to respond in writing or attend a meeting.
• Genuinely consider their response: Weigh their input and any alternative options before making your final, written decision.

The One Essential Truth of Managing Absenteeism

If there is one thing to remember tomorrow when you log on and face another notification of a sick day, it is this: the law does not prevent you from managing employee absenteeism; it prevents you from doing so without a process. The most common and costly mistake Australian business owners make is assuming that because an employee has run out of accrued paid personal leave, they can be immediately let go. In reality, the end of paid leave is simply the start of a much more demanding legal framework that requires genuine empathy, clear consultation, and objective medical evidence before any decisive action is taken.

Managing an employee with excessive sick leave requires a systematic approach that balances operational needs with strict compliance under the Fair Work Act 2009 (Cth). Employers must first calculate the employee's exact leave balances and understand the "temporary absence" protections under s 352 of the Act and reg 3.01 of the Fair Work Regulations 2009 (Cth), which shield workers on paid leave or those away for less than three consecutive months. By establishing clear notification policies, requesting valid medical certificates, conducting supportive consultations, and thoroughly assessing the inherent requirements of the role before considering termination, you can mitigate the risk of expensive unfair dismissal, discrimination, or general protections claims. When navigating these high-risk procedures, obtaining professional legal guidance from Artificer Legal ensures your business remains protected while fostering a fair, compliant, and supportive workplace.
