Sick Employees At Work: Employer Responsibilities In Australia

When a team member turns up unwell, you’re juggling people, productivity and legal obligations all at once. Knowing what you can ask, when you need to pay, and how to keep everyone safe can feel complex - especially because each situation is a little different.

The good news is there are clear rules you can follow. With a sensible policy, the right contracts and a supportive approach, you can protect your people and your business while staying compliant with Australian law.

In this guide, we’ll walk through your core duties when an employee is sick at work, when you can seek evidence, how sick leave and pay works, and the best practical steps to implement now.

Your Core Legal Duties When Someone Is Sick At Work

As an employer in Australia, your responsibilities start with safety and extend to leave entitlements, privacy and fair treatment under workplace laws.

Provide A Safe Workplace (WHS)

Under work health and safety (WHS) laws, you must take reasonable steps to keep your workplace safe. If a staff member is visibly unwell (for example, with a contagious illness, a fever or signs they can’t safely perform their role), you can direct them to stop work, leave the premises, or work from home (if suitable) to reduce risk to others.

“Reasonable steps” may include basic infection controls (sanitiser, cleaning, distancing), adjusting duties, or temporarily reassigning tasks if someone is unwell but able to work safely in a modified way.

Respect Minimum Employment Standards

Employees covered by the National Employment Standards (NES) are entitled to paid personal/carer’s leave (often called sick leave) if they’re full-time or part-time. Casual staff don’t accrue paid sick leave, but they can take unpaid carer’s leave in certain circumstances and may have additional entitlements under an award or enterprise agreement.

Leave requests should be considered promptly and fairly. You can ask for evidence (more on that below) if the request is reasonable in the circumstances.

Avoid Adverse Action Or Discrimination

It’s unlawful to take adverse action against an employee for exercising a workplace right (such as taking paid personal leave) or because of disability or illness. Manage attendance and performance issues in a consistent, documented and fair way, focusing on capability and reasonable adjustments rather than the illness itself.

Keep Health Information Private (And Understand The Employee Records Exemption)

Health information is sensitive. Treat any medical details as confidential and restrict access to what’s strictly necessary for managing work and safety. Only collect what you need and store it securely.

In the private sector, the Privacy Act’s “employee records exemption” can apply to personal information held by an employer and directly related to the employment relationship. However, it doesn’t give you a free pass to over-collect health information, and it doesn’t generally apply to prospective employees or contractors. WHS duties, anti-discrimination laws and good privacy practice still require you to handle medical details carefully and on a “need to know” basis.

Requesting Evidence: Medical Certificates, Stat Decs And Fitness For Work

Employers can request reasonable evidence that an employee is genuinely unwell or caring for an immediate family or household member. Usually this is a medical certificate or a statutory declaration confirming the employee could not work because of illness or injury (or needed to provide care).

When Can You Ask?

• You can request evidence for any personal/carer’s leave absence if it’s reasonable in the circumstances - for example, where there are patterns of absence, the role is safety‑sensitive, the timing is critical for operations, or you have genuine concerns about fitness for work.
• Many awards and enterprise agreements allow an employer to ask for evidence after any absence (not only after consecutive days). The NES also supports evidence requests that are reasonable based on context.
• If an employee doesn’t provide reasonable evidence when requested, you can refuse paid personal/carer’s leave for that period (but consider unpaid options if appropriate).

Set expectations in your policies so everyone is clear on when evidence is required. For a deeper dive into practical rules and examples, see guidance on medical certificates.

What Should The Evidence Say?

You don’t need a diagnosis. A simple statement from a registered health practitioner that the employee “is/was unfit for work” on specified dates is usually sufficient. Avoid requesting detailed medical history or sensitive information that isn’t necessary to manage attendance or safety.

Can You Require A Medical Clearance To Return?

In higher-risk roles or where there’s a genuine safety concern, you can ask for a fitness‑for‑work clearance to make sure the employee can safely resume duties. Keep the request reasonable, targeted and proportionate to the role and the circumstances.

Paying Sick Leave And Managing Entitlements Correctly

Understanding when to pay, how leave accrues, and what to do when balances are low will help you avoid disputes and stay compliant.

How Sick Leave Accrues

• Full-time employees accrue 10 days of paid personal/carer’s leave per year (pro‑rated for part‑time), accruing progressively based on ordinary hours.
• Unused paid personal/carer’s leave carries over from year to year under the NES.
• Casual employees do not get paid sick leave under the NES, but may access unpaid carer’s leave or other entitlements under an applicable award or agreement.

Is Sick Leave Cashed Out On Termination?

No. Unused paid personal/carer’s leave is not paid out on termination under the NES. This is different to annual leave, which may be paid out on termination under certain instruments.

If You Send Someone Home, Do You Have To Pay?

If an employee is unfit for work due to illness or injury, they can access paid personal/carer’s leave (if they have an accrued balance). If they have no balance, consider options like working from home (if safe and feasible), using annual leave (by agreement), or unpaid leave.

Standing an employee down without pay is only allowed in limited circumstances (for example, a stoppage of work outside your control). Sickness itself is not a stand‑down scenario. If you direct an otherwise ready and willing employee to leave for precautionary reasons (and they’re fit to work), seek advice before withholding pay.

What If Sick Leave Runs Out?

When an employee’s personal leave balance is low or zero, plan next steps together. Options may include annual leave by agreement, unpaid leave, remote work, or temporary adjustments to duties or hours. Practical options and risk points are set out in this guide to managing sick leave when entitlements run out.

Sick Leave During The Notice Period

Employees remain entitled to personal/carer’s leave during their notice period if they are genuinely unwell. This can affect their final days at work, handover and pay calculations. Make sure managers understand the rules around sick leave during a notice period and document communications carefully.

Unpaid Carer’s Leave And Compassionate Leave

• Unpaid carer’s leave is available when paid personal/carer’s leave is exhausted, or for casuals who need to care for a family or household member.
• Compassionate leave (paid for permanent employees, unpaid for casuals) applies when a member of the employee’s immediate family or household dies or suffers a life‑threatening illness or injury.
• Use of unpaid leave should be consistent and policy‑based. A quick reference on expectations is outlined in these leave without pay rules.

Balancing Safety, Privacy And Mental Health Day-To-Day

Supporting employees while managing business risk often requires judgment. These principles will keep you on track.

Safety First (And Document Your Reasoning)

If someone is too unwell to work safely, you can direct them to stop work or leave the site. Make a short, factual file note of your reasons (symptoms observed, safety concerns, actions taken) and any alternatives you offered (remote work, adjusted duties). Good notes help if questions arise later.

Privacy And Consent - Collect Only What You Need

Keep medical information confidential and limit what you collect. If you need specific information to understand capability or reasonable adjustments, use a targeted consent process. A simple Medical Release Consent Form can help you obtain only relevant details with the employee’s permission.

It’s also helpful to document your approach in clear procedures, such as an Employee Privacy Handbook that covers health information, consent and retention periods.

Mental Health Is A Workplace Issue Too

Mental health conditions can affect attendance and performance just like physical illness. Your duty of care includes taking reasonable steps to support mental health at work - for example, workload adjustments, flexible hours or referral to an employee assistance program (EAP). Obligations and practical steps are explained in this overview of Fair Work obligations regarding employee mental health.

Reasonable Adjustments And Inherent Requirements

Where a health condition impacts work, focus on the “inherent requirements” of the role - the core tasks the employee must be able to perform. You may need to make reasonable adjustments (temporary or permanent) to help the employee meet those requirements, provided it’s not an unjustifiable hardship for the business.

Preventing Misuse Without Overreach

Most people do the right thing. If you’re concerned about potential misuse, rely on your policies, evidence requests and normal performance management processes. Avoid blanket assumptions or intrusive requests for medical detail. Treat each case on its merits and apply your procedures consistently.

Practical Steps: Policies, Contracts And Training That Make This Easier

A clear framework keeps everything fair and consistent across teams and managers. Here’s what to put in place now.

1) Employment Contracts That Set Expectations

Ensure each employee has a written contract that sets out hours, classification, remuneration, and how leave is requested and approved. Clear wording reduces disputes about availability and rostering when someone is unwell. If you’re updating templates, consider a tailored Employment Contract for full‑time and part‑time roles (with separate casual agreements where applicable).

2) A Staff Handbook And Leave Policy

Codify your approach to personal/carer’s leave, carer’s leave, evidence requirements, notification timelines (who to contact, by when), and return‑to‑work steps. A well‑written Staff Handbook helps managers respond consistently and sets clear expectations for employees.

3) A Clear Process For Evidence And Fitness For Work

Spell out when you’ll ask for a medical certificate, how to submit it, and when a fitness‑for‑work clearance is required (for example, after extended illness or for safety‑critical tasks). Reference the types of evidence you accept and keep the policy practical and easy to follow.

4) Privacy And Health Information Handling

Limit what you collect, secure it properly, and restrict access on a “need to know” basis. Your privacy procedures should address collection, consent, storage, access and retention of health information, and clarify how the employee records exemption interacts with your WHS and anti‑discrimination obligations.

5) Return-To-Work Planning

For longer absences, a simple return‑to‑work plan can clarify duties, temporary adjustments, check‑in dates and any evidence you’ll need. Involve the employee so the plan is collaborative and realistic.

6) Train Managers On Conversations And Records

Brief supervisors on how to handle sick calls, when to seek evidence, privacy boundaries and the basics of WHS and discrimination law. Encourage short, factual file notes of key decisions (without medical detail). Confidence at the frontline prevents most issues from escalating.

7) Have A Pathway For Complex Scenarios

From extended absences to competing safety and privacy concerns, some situations need tailored advice. Keep a simple escalation path (HR or your legal adviser) so managers know where to turn quickly. If you need to refresh the fundamentals, this guide sits alongside practical resources like policies, contracts and topic‑specific explainers on certificates, leave balances and notice periods.

Key Takeaways

• Your core duties are safety, lawful leave management, privacy and fair treatment. Get these right and most sick leave situations are straightforward.
• It’s reasonable to ask for evidence for personal/carer’s leave where appropriate; keep requests proportionate and avoid seeking diagnoses.
• Paid personal/carer’s leave accrues and carries over year to year, but it is not cashed out on termination under the NES.
• Standing down without pay is limited to narrow circumstances - sickness itself is not a stand‑down scenario, so take care with any “sent home” decisions.
• When balances are low, consider annual leave by agreement, unpaid leave, adjusted duties or remote work, and use a simple return‑to‑work plan for longer absences.
• Protect privacy with consent‑based, targeted requests and store health information securely; support mental health as part of safety and wellbeing.
• Strong foundations - an Employment Contract, a clear Staff Handbook, and practical privacy and evidence procedures - help managers act consistently and lawfully.
