Mental Health Sick Leave Explained
Learn how mental health sick leave works for stress, burnout, and legal rights.

Mental health issues like stress and burnout are common in the workplace, workers are questioning how to get adequate support, and what can business do the best support them. Questions and the legal and practical aspects of taking mental health leave also tends to exacerbate the issue.
In this article, we clarify what it means to take a mental health days off, the legal entitlements, and how employers and employees can effectively manage mental health in the workplace.
What is Mental Health Sick Leave?
Mental health sick leave refers to the time taken off work by an employee to address and recover from mental health issues.
This type of leave is recognised as equally important as leave taken for physical illnesses or injuries. When an employee feels mentally unwell, they have the right to take time off to rest, seek professional help, and recuperate, ensuring they can return to work with a clearer and healthier mindset.
This kind of leave could be considered as part of a workers personal and carers leave access, though some workplaces will go one step further and have a dedicated leave day for mental health.

Reasons for Taking Mental Health Sick Leave
Employees might need to take mental health leave for various reasons, including but not limited to:
Stress
High levels of workplace stress can lead to mental exhaustion and decreased productivity. Taking time off allows employees to decompress and address the root causes of their stress.
Burnout
Chronic workplace stress can result in burnout, characterised by emotional exhaustion, detachment, and a sense of ineffectiveness. Mental health leave can provide the necessary break to recover and rejuvenate.
Bereavement
The loss of a loved one can significantly impact mental health. Employees may need time to grieve and process their emotions without the added pressure of work responsibilities.
Mental Health Conditions
Diagnosed conditions such as depression, anxiety, OCD, PTSD, ADHD, and eating disorders may require time off for treatment, therapy sessions, or simply to rest.
Personal Issues
Other personal challenges, such as relationship problems or significant life changes, can affect mental wellbeing. Taking mental health leave can help employees cope with these issues more effectively.

Comparison with Physical Illness or Injury Leave
Mental health sick leave should be treated with the same seriousness as physical illness or injury leave. Just as an employee with the flu or a broken leg would take time off to heal, an employee struggling with mental health issues such as anxiety, depression, or severe stress requires time away from work to focus on their wellbeing.
The process for requesting mental health leave, including notifying the employer and providing necessary documentation, should mirror the procedures for physical health-related absences.
Legal Framework and Workplace Obligations
The Fair Work Act 2009 and the National Employment Standards (NES) are the primary legal frameworks governing employment conditions in Australia.
These laws ensure that all employees, except casual workers, are entitled to personal/carer’s leave, which can be used for mental health reasons. The NES guarantees full-time and part-time employees 10 days of paid personal leave per year.
Under the NES, mental health issues, including stress, anxiety, and depression, can fall under personal illness, allowing employees to use this leave for mental health reasons. This leave accrues progressively throughout the year and carries over from year to year if not used.
Employees can use their accrued personal leave for any period during which they are unfit for work due to mental health issues. If an employee exhausts their personal leave entitlements, they may be able to access other forms of leave, such as annual leave or unpaid leave, depending on their circumstances and the employer’s policies.
Employer’s Legal Duty of Care
Employers have a legal duty of care to ensure the health, safety, and wellbeing of their employees, which includes both physical and mental health. This duty is enshrined in the Work Health and Safety (WHS) laws, which require employers to provide a safe working environment and take reasonable steps to prevent risks to mental health.
Obligations to Provide a Mentally Safe Working Environment
Employers are obligated to identify and mitigate risks that could adversely affect employees’ mental health. This includes addressing factors such as excessive workload, workplace bullying, and inadequate support systems.
Benefits of a Specific Mental Health Leave Day
A dedicated mental health leave policy provides several key benefits for both employees and employers:
Reduction of Stigma
Having a specific policy helps normalise mental health issues, reducing the stigma often associated with taking time off for mental health reasons. This encourages employees to seek help when needed without fear of judgment or negative consequences.
Clarity and Consistency
A clear policy ensures that all employees understand their rights and the procedures for taking mental health sick leave. This consistency helps avoid confusion and ensures that all employees are treated fairly and equally.
Legal Compliance and Protection
A specific policy ensures that the company complies with legal obligations regarding mental health and workplace safety. This can protect the company from potential legal disputes related to discrimination or failure to provide reasonable adjustments.
Positive Workplace Culture
Promoting mental health awareness and support fosters a positive and inclusive workplace culture. This can enhance teamwork, employee morale, and attract top talent who value a supportive work environment. Mental health sick days are a crucial component of a comprehensive mental health policy in the workplace.
However, they should be integrated into a broader strategy that includes proactive measures such as psychosocial risk assessments and Employee Assistance Programs (EAP) counselling.
According to the Queensland Human Rights Commission, approximately 1 in 5 Australians have taken time off work due to a mental illness.
