Fair Work Obligations Regarding Employee Mental Health (Australia)

Mental health is central to a safe, productive workplace. As an employer in Australia, you’re required to manage psychological risks at work and handle mental health–related leave and issues lawfully and respectfully.

That can feel daunting if you’re not sure where the Fair Work Act stops and where work health and safety obligations begin. The good news is that once you understand the key duties and put the right policies and documents in place, supporting your team becomes much easier.

In this guide, we’ll walk through your legal obligations around mental health, which types of leave can apply, how to respond to mental health disclosures and requests, and the practical documents and processes you should have in place to protect your people and your business.

What Are Your Legal Duties Around Mental Health At Work?

In Australia, obligations around psychological health at work sit across a few legal frameworks. Understanding how they fit together is the first step to compliance.

1) Work Health And Safety (WHS) – Psychosocial Risk Management

Under work health and safety laws (in each state and territory), a person conducting a business or undertaking (PCBU) must ensure, so far as is reasonably practicable, the health and safety of workers. “Health” includes psychological health. This means you must identify, assess and control psychosocial hazards such as excessive workload, low job control, bullying, harassment, occupational violence, remote or isolated work, and poor role clarity.

In practice, that involves consulting workers, implementing policies, training managers, monitoring workloads and hours, and responding to concerns early. It’s part of your broader duty of care as an employer to provide a safe workplace.

2) Fair Work Act 2009 (Cth) – Leave, Flexible Work And Protections

The Fair Work Act sets out the National Employment Standards (NES) and protections enforced by the Fair Work Commission. Relevant obligations include:

• Personal/carer’s leave (paid sick leave) for illness or injury, which includes mental health conditions.
• Requests for flexible working arrangements (for eligible employees) which can include adjustments linked to disability (a mental health condition may meet the definition).
• General protections (adverse action) – you must not take unlawful adverse action against an employee because they have a mental health condition, have exercised a workplace right (e.g. to take leave), or because of temporary absence due to illness/injury in accordance with the Act.
• Stop-bullying/stop-sexual harassment orders via the Fair Work Commission, if there’s a risk to health and safety from unreasonable behaviour.

3) Anti-Discrimination – Reasonable Adjustments

Under federal and state/territory discrimination laws, you must not discriminate against a worker because of disability, which includes many mental health conditions. You also need to consider reasonable adjustments to help an employee perform the inherent requirements of their role, unless this would cause unjustifiable hardship. Adjustments might include altered hours, different duties, or changes to supervision or workload.

4) Privacy – Handling Health Information

Health information is sensitive information. Many private sector employers are subject to the Privacy Act 1988 (Cth) and the Australian Privacy Principles (APPs). There is an “employee records” exemption for some information held by private sector employers, but it is limited and does not apply to prospective employees or to information collected by third parties on your behalf. Even where an exemption applies, good practice is to collect only what’s reasonably necessary, limit access on a need-to-know basis, and store it securely. An Employee Privacy Handbook is a practical way to embed these standards in your business.

What Leave Can Employees Use For Mental Health?

There’s no special “mental health day” classification in Australian employment law. However, employees can use existing NES leave entitlements when mental health affects fitness for work.

Personal/Carer’s Leave (Paid Sick Leave)

Full-time employees are entitled to 10 days of paid personal/carer’s leave per year, accruing progressively. Part-time employees accrue this on a pro‑rata basis. This leave can be used when an employee is unfit for work due to illness or injury, including depression, anxiety, acute stress, burnout or other mental health conditions.

If the issue is short-term (for example, a single day due to acute stress), it’s still personal leave if the employee is unfit for work that day. If the condition is ongoing, the employee may use accrued leave as needed, in line with notice and evidence requirements.

Carer’s Leave

Employees can also use personal/carer’s leave to provide care or support to an immediate family or household member who is ill or injured, including where that person is experiencing a mental health episode.

Unpaid Leave When Paid Leave Is Exhausted

There’s no automatic entitlement to extended unpaid sick leave under the NES. However, employers and employees often agree to a period of unpaid leave once paid personal leave is exhausted, especially in longer-term mental health situations. Clear policies make decision-making easier and help you stay consistent across your team. If you’re considering this option, it’s worth reviewing your approach to leave without pay rules to ensure your process is fair and documented.

Workers’ Compensation (If Work-Related)

Where a psychological injury is caused by work, workers’ compensation and return-to-work obligations may apply. These schemes are state-based and sit alongside your WHS duties and Fair Work obligations.

Evidence For Leave

You can request evidence that would satisfy a reasonable person that the employee is unfit for work. A medical certificate or statutory declaration is commonly used. Your policies and contracts should explain when evidence is required (for example, for single-day absences or patterns of absence) to set clear expectations and ensure consistent treatment across the workforce.

“Stress Leave” And “Mental Health Days”

Terms like “stress leave” or “mental health day” are informal. In practice, time off taken due to mental ill-health is personal/carer’s leave. If the employee has no leave balance, you might agree on unpaid leave or consider temporary adjustments to hours or duties. For practical tips on navigating these requests, see our guide to managing employee stress leave.

How Should You Respond To A Mental Health Disclosure Or Leave Request?

When an employee tells you they are struggling, or they request leave linked to mental health, a fair, consistent response reduces risk and supports recovery.

1) Acknowledge And Maintain Privacy

Thank the employee for raising it and acknowledge the impact. Limit any request for details to what is necessary to administer leave, make reasonable adjustments, and manage safety. Keep documentation secure and restrict access to those who genuinely need it for HR or safety reasons.

2) Process Leave Under The NES

Approve personal/carer’s leave where the employee is unfit for work, in line with your policies and any applicable award or enterprise agreement. If evidence is required, set out what’s needed and by when. Avoid unnecessary delays in confirming leave outcomes during a period of illness.

3) Consider Reasonable Adjustments And Flexible Work

Discuss whether temporary or longer-term adjustments could help the employee return to work or stay at work safely. This could include reduced hours, different start/finish times, changes to duties, or work location changes. For eligible employees, the Fair Work Act also provides a right to request flexible working arrangements, which you must respond to within the statutory timeframe and on permissible grounds.

4) Manage Risks And Plan The Return To Work

If the absence has been longer or the role has inherent safety risks, it can be appropriate to request medical input about fitness for duty and any recommended restrictions. A measured return-to-work plan can set expectations for the employee, manager and team. Where appropriate, you can request a clearance from a treating practitioner in line with your policies and the inherent requirements of the role; here’s a helpful overview on requesting medical clearance to return to work.

5) Address Bullying Or Conflict Early

Concerns about bullying, harassment or workload pressure must be taken seriously. Act promptly, follow your grievance or conduct process, and put immediate controls in place where there is a risk to health and safety. The Fair Work Commission can make stop-bullying or stop-sexual harassment orders where there’s a risk to health and safety from unreasonable conduct, so early, fair management is essential.

Do You Need Workplace Policies And Documents?

Clear documents make it easier to apply the rules fairly and consistently, which reduces legal risk and builds trust in your processes. At a minimum, most employers should consider the following.

Employment Contracts

Modern, well-drafted contracts should reference applicable awards, set out notice and evidence requirements for personal/carer’s leave, address privacy expectations around medical information, and outline performance and conduct requirements. Having a standard Employment Contract for full-time and part-time staff is a simple way to align your practices with the NES and any enterprise agreement or award.

Workplace Policies

Policies help implement your WHS, Fair Work and anti-discrimination duties day to day. Useful inclusions are:

• Mental Health And Wellbeing Policy: Sets your commitment to a psychologically safe workplace, outlines available supports (e.g. EAP or external helplines), and explains how staff can raise concerns.
• Bullying, Harassment And Discrimination Policy: Defines unacceptable conduct, reporting options, investigation processes and potential outcomes.
• Leave Policy: Explains notice and evidence for personal/carer’s leave and how you handle unpaid leave requests once paid leave is exhausted.
• Flexible Work Policy: Describes how requests are made and assessed, and statutory response timeframes.
• Privacy And Information Handling: Explains how health information is collected, stored and accessed, and where the employee records exemption does and doesn’t apply.

If you don’t have these yet or they need a refresh, a single Staff Handbook can bring your core policies together in one place, or you can implement a standalone Workplace Policy to address a specific gap.

Privacy Documents

Depending on your size and activities, you may need (or choose to implement) privacy documents that reflect how you collect, use and store personal and sensitive information. Beyond public-facing documents, internal guidance like an Employee Privacy Handbook helps managers and HR handle medical notes, certificates and case files consistently and securely.

Manager Training And Process Checklists

Even the best policy won’t work if managers don’t know how to apply it. Train your leaders in spotting psychosocial risks, having supportive conversations, documenting decisions, and escalating concerns correctly. A simple checklist for “mental health disclosure/leave request received” can reduce mistakes in the moment.

Common Compliance Pitfalls (And How To Avoid Them)

Most issues arise not from a lack of care, but from unclear processes or mixed messages. Here are common risks to watch for.

1) Confusing WHS And Fair Work Obligations

WHS is about proactively eliminating or minimising risks to psychological health. The Fair Work Act governs minimum employment standards, protections and dispute processes. You need to comply with both. For example, tackling a workload issue is primarily a WHS control; approving personal leave for the person impacted is a Fair Work obligation.

2) Inconsistent Evidence Requirements

If you “sometimes” request certificates and “sometimes” don’t, staff may feel singled out, and managers can make inconsistent calls under pressure. Align your Employment Contracts and leave policy so everyone knows when evidence is needed and why. Consistency is key to fairness.

3) Mishandling Sensitive Health Information

Only collect information that’s necessary, keep it secure, and limit access. Where you are subject to the Privacy Act, ensure you only collect sensitive information (like health information) with consent or under a permitted exception. Even where the employee records exemption applies, best practice is to apply APP-style safeguards internally.

4) Dismissing Too Quickly During Illness

Termination during a mental health–related absence can trigger unfair dismissal or general protections claims, especially if you don’t have clear medical evidence about fitness for work and haven’t explored reasonable adjustments. If performance concerns continue after support and adjustments, use a fair, documented performance process that gives the employee a reasonable opportunity to respond.

5) Leaving Psychosocial Hazards Uncontrolled

Bullying, unclear roles, chronic overwork, or lack of support can create ongoing risk and repeated absences. Consult with workers, review staffing and resourcing, and implement controls (such as workload balancing, role clarity, leadership training and respectful workplace programs). Prevention is more effective than reacting to each absence.

Practical Steps To Build A Mentally Healthy Workplace

Compliance is the floor, not the ceiling. These practical actions will help you go further and reduce risk across your business.

• Map Your Psychosocial Risks: Identify where stressors occur (workload spikes, customer aggression, isolated work, poor role clarity) and implement specific controls.
• Train Managers: Equip leaders to have supportive conversations, apply policies consistently, and escalate concerns early. Confidence here reduces missteps.
• Normalise Help-Seeking: Encourage staff to use personal leave when unwell and promote support options (EAP, Lifeline, Beyond Blue). Make it clear that mental health is treated like any other health issue.
• Use Clear Checklists: Standardise responses to disclosures, leave requests, and return-to-work planning so every worker has a consistent experience.
• Review Work Design: Monitor hours, workload, KPIs and rostering to avoid chronic overwork and role conflict. Consult with your team on changes.
• Document Decisions: Keep respectful, factual records of conversations, agreed adjustments, and reviews. Good documentation protects all parties if issues escalate.

Key Takeaways

• WHS laws require you to manage psychosocial risks proactively; psychological health is part of providing a safe workplace.
• The Fair Work Act covers personal/carer’s leave for mental ill-health, flexible work requests for eligible employees, and protections against adverse action.
• There is no separate “mental health day” entitlement; time off for mental health is generally personal/carer’s leave, with evidence requirements set by your policies.
• Anti-discrimination laws require reasonable adjustments unless doing so would cause unjustifiable hardship, and privacy rules apply to handling health information.
• Clear documents matter: align your Employment Contracts, implement a Staff Handbook or targeted Workplace Policies, and give managers simple checklists to follow.
• When paid leave runs out, you can consider agreed unpaid leave and temporary adjustments; set expectations clearly and handle medical information carefully, supported by an Employee Privacy Handbook.
• Early, supportive responses, consistent processes and good documentation reduce legal risk and help your team stay healthy and productive.
