Looking after your team is good business and a legal requirement. One area that regularly comes up for Australian employers is “stress leave” - when an employee is unfit for work due to stress, anxiety, burnout or another mental health condition.
If you manage people, it’s important to know how stress leave works under the Fair Work system, when it’s paid, what evidence you can request, and how to balance compassion with compliance. Done right, you’ll protect your people and reduce legal risk.
In this guide, we’ll explain how stress leave fits within Australia’s employment laws, practical steps to manage requests, where unpaid time off fits in, and what to do if absences become long-term or recurring.
What Is Stress Leave Under Australian Law?
There isn’t a separate legal category called “stress leave” in the Fair Work system. In practice, stress-related absences sit within personal/carer’s leave (often called sick leave) under the National Employment Standards (NES) in the Fair Work Act 2009.
Personal/carer’s leave covers illness or injury that makes an employee unfit for work - this includes mental health conditions like stress, anxiety or depression. If an employee says they are unwell due to stress and cannot safely perform their role, the usual personal leave rules apply.
It’s also part of your broader duty to provide a safe workplace. Employers owe a duty of care to manage risks to health and safety, including psychosocial hazards like high job demands, bullying or poor role clarity. Treat stress-related absences as both a leave and a health and safety issue.
For most private sector workplaces, these entitlements are national and don’t change from state to state. Some public sector or health roles may have extra provisions in enterprise agreements, but the core approach above still applies unless your enterprise agreement says otherwise.
Is Stress Leave Paid And How Much Can Employees Take?
Full-time and part-time employees are entitled to paid personal/carer’s leave when they are unfit for work due to illness or injury (including stress). The NES entitlement is 10 days per year for full‑time staff, pro‑rated for part‑time staff. It accrues progressively and carries over year to year.
When paid personal leave is used, it’s paid at the employee’s base rate for their ordinary hours (no loadings, penalties or overtime). Make sure your payroll records it as paid personal leave rather than annual leave unless the employee specifically requests to use annual leave and you agree.
What About Casual Employees?
Casual employees don’t receive paid personal/carer’s leave. However, all employees (including casuals) can take up to two days of unpaid carer’s leave per occasion to provide care or support to an immediate family or household member who is ill or injured, or in an unexpected emergency.
If a casual employee is themselves unfit for work due to stress, there is no separate NES entitlement to “unpaid sick leave.” A casual can be unavailable for a shift, and you should manage that in line with your rostering and evidence practices. Longer unpaid time off is by agreement.
Can Employees Take Unpaid Time Off For Stress?
After a permanent employee has exhausted their paid personal leave balance, any additional time off for their own illness or injury is not automatically an NES entitlement. You may agree to unpaid leave, or the employee may choose to access annual leave (by request, subject to your approval). Your policies and the relevant award or enterprise agreement may also provide options.
For clarity, treat any unpaid time off for an employee’s own illness as unpaid leave by agreement, distinct from the two days of unpaid carer’s leave (which is for caring responsibilities, not the employee’s own illness).
How To Apply And What Evidence Can You Require?
Stress-related absences should follow the same process as other personal (sick) leave. A clear, consistent approach helps you support staff and stay compliant.
1) Notification
Employees should let you know as soon as possible that they are unfit for work and, if they can, indicate the expected length of absence. Your workplace policies should state who to notify and by when (for example, their direct manager by phone before the shift starts).
2) Evidence Requirements
You can require appropriate evidence that would satisfy a reasonable person that the employee was unfit for work. This could be a medical certificate or a statutory declaration, and you may request evidence even for short absences if your policy says so. For longer or recurring absences, evidence should be standard practice. For more detail on setting expectations, see when you can request medical certificates.
3) Payroll And Recordkeeping
Record the absence correctly as paid personal leave (if accrued and approved) or unpaid leave by agreement. Accurate records help with compliance and trend-spotting if absences increase over time.
4) Privacy And Communication
Keep medical information confidential and limit access to those who need to know. During any absence, maintain respectful, periodic contact about capacity to work and return-to-work planning without pressuring the employee to return before they’re fit.
5) Return-To-Work Clearances
For extended absences or safety-critical roles, it’s reasonable to request a “fit to work” note or to clarify any temporary restrictions to plan suitable duties. Manage this sensitively and consistently across your workforce.
Managing Extended Or Recurring Stress Leave
Repeated or long-term absences call for a structured, lawful approach. The aim is to support the employee, reduce risk and make sound decisions based on evidence.
Temporary Absence Protection (The 3‑Month Rule)
Under the Fair Work Act, employees are protected from dismissal because of a temporary absence due to illness or injury if the absence is less than three months, or if total absences in a 12‑month period are less than three months, and the employee provides reasonable evidence (for example, medical certificates). Once the absence exceeds these thresholds, the specific “temporary absence” protection may no longer apply.
Important: Losing that specific protection does not give a green light to dismiss. Other laws still apply, including general protections, anti-discrimination laws, and unfair dismissal laws (depending on eligibility). Always take care and seek advice before making decisions about employment where illness or injury is involved.
Reasonable Adjustments And Role Changes
If a medical condition affects a person’s capacity, consider reasonable adjustments, such as temporary modified duties, reduced hours or altered reporting lines. What’s “reasonable” will depend on your business size, the role, and medical guidance. Document discussions and trial periods so everyone is clear on expectations.
Independent Medical Assessments
In complex cases, you may consider an independent medical assessment to clarify capacity, prognosis and any workplace supports required. This should be handled respectfully, with clear reasons and appropriate consents.
Ill Health Termination
Ending employment for incapacity is a last resort and must follow a fair, evidence‑based process that aligns with the employee’s rights under workplace and discrimination laws. See our guide on termination on medical grounds for key steps and risks to consider.
Unpaid Leave And Alternatives
When paid entitlements are exhausted, consider options like unpaid leave by agreement, annual leave (by request), or a short pause on duties while you implement adjustments. Our overview of unpaid leave explains how these arrangements typically work in practice.
Your WHS Duties And Practical Adjustments
Stress leave often signals a work health and safety (WHS) issue. Employers must identify, assess and control psychosocial hazards so far as is reasonably practicable. This isn’t just compliance - it prevents harm and helps retention.
Psychosocial Risks To Watch
- High or sustained workloads, long hours or insufficient staffing
- Unclear roles, poor change management or conflicting priorities
- Bullying, harassment or unreasonable performance pressure
- Poor supervisor support or lack of training and resources
- Exposure to traumatic events or challenging client behaviour
Have a simple, documented risk management approach: consult with workers, assess risks, implement controls, and regularly review what’s working. Your mental health obligations sit alongside your duty to prevent physical injury - treat them with the same seriousness.
Practical Steps You Can Take
- Set realistic workloads and monitor peaks that create burnout risk
- Provide manager training on mental health conversations and early intervention
- Offer flexible work or temporary duty changes based on medical advice
- Consider an Employee Assistance Program (EAP) and promote it actively
- Establish a respectful culture with quick responses to bullying or conflict
- Use clear, consistent workplace policies so everyone understands the process
If you’re hiring or updating contracts, make sure each team member has an up‑to‑date Employment Contract that aligns with awards or enterprise agreements and references the NES personal/carer’s leave entitlement.
Policies, Documents And Day-To-Day Good Practice
Clear documents and consistent practices make stress leave easier to manage and reduce disputes. Aim to implement the following.
Core Documents To Have In Place
- Sick Leave / Personal Leave Policy: Sets out how to notify absences, when evidence is required, privacy, and return‑to‑work steps.
- WHS Policy (including psychosocial risk): Confirms your commitment to mental health and outlines risk management and reporting.
- Employment Contract: Aligns with the NES and any applicable award/enterprise agreement, clarifies evidence and communication expectations.
- Performance And Capability Procedure: Explains how you’ll assess fitness for work, approvals for adjustments, and escalation steps.
- Privacy Practices: Restrict access to medical information, store it securely, and only use it for lawful workplace purposes.
Fair And Lawful Processes
- Apply evidence requirements consistently across physical and mental health absences.
- Don’t challenge genuine medical certificates without a valid, evidence‑based reason (for example, suspected fraud).
- Contact absent employees respectfully and at reasonable intervals - avoid pressure to return before medically fit.
- Keep comprehensive records: certificates, communications, adjustments and return‑to‑work plans.
- If long‑term incapacity is on the table, follow a structured pathway and consider advice before decisions that may affect employment. See our overview of termination on medical grounds for a high‑level checklist.
If prolonged absence means you’re contemplating a change in role or employment, ensure your approach aligns with the employee’s rights and the steps discussed above.
