Can Employees Use Annual Leave For Sick Leave?

When you’re running a small business or startup, leave requests can feel like a constant balancing act.

On the one hand, you want to support your team when they’re unwell. On the other, you need to keep your business operating, stay compliant with the Fair Work framework, and make sure your payroll and leave records are accurate.

A common question we hear is: can an employee use annual leave when they’re sick, instead of (or after) personal/carer’s leave?

In some situations, annual leave can be used when someone is sick - but you need to be careful about when that’s allowed, and what you’re required to do under the National Employment Standards (NES), as well as any applicable award or enterprise agreement. It’s also important that any decision is properly documented and recorded in payroll (rather than handled informally).

Below, we’ll walk you through what Australian employers need to know about using annual leave when an employee is sick, including the compliance risks to watch for and a practical process you can apply in your business.

Can Employees Use Annual Leave For Sick Leave In Australia?

In Australia, most employees have access to different types of leave for different purposes. The two that matter most here are:

• Personal/carer’s leave (sick leave): paid leave available when an employee is unfit for work due to illness or injury (and also for caring responsibilities in certain circumstances).
• Annual leave: paid leave intended for rest and recreation (often taken for holidays, breaks, and planned time away from work).

From an employer perspective, the key point is this: sick leave and annual leave are not interchangeable by default. They exist for different reasons, and your approach needs to reflect that.

What If The Employee Still Has Sick Leave Available?

If the employee is sick and has paid personal/carer’s leave available, the usual (and safest) approach is to record their absence as personal leave - provided they give notice as soon as practicable and meet any reasonable evidence requirements you have (for example, a medical certificate or statutory declaration).

Sometimes an employee may ask to use annual leave instead (for example, because they want to preserve their personal leave balance). If that happens, be cautious: you should not direct or pressure an employee to use annual leave instead of personal leave, and you should check any award/enterprise agreement and your workplace documents for specific rules. Where it’s permissible, make sure it’s clearly the employee’s choice and that you keep a written record of the request and your response.

If you want the deeper Fair Work-style breakdown, the principles are covered in our guide on using annual leave for sick leave.

What If The Employee Has No Sick Leave Left?

If the employee has run out of paid personal leave, you still have options, but you should treat them carefully and consistently. Depending on the situation, options can include:

• Annual leave (if the employee requests it and you approve it)
• Unpaid leave (often relevant if there’s no paid leave available)
• Other leave types (for example, long service leave in some circumstances, depending on the state/territory rules and eligibility)

For many businesses, the big operational risk here is inconsistency: approving annual leave “as sick leave” for one person, but refusing another without a clear policy rationale.

What If Someone Gets Sick While On Annual Leave?

This one comes up a lot in practice, especially around Christmas shutdown periods and peak leave times.

If an employee is already on annual leave and becomes sick, they can generally take personal leave for the period they’re unfit for work - and if they meet the notice and evidence requirements, you should treat that period as personal leave rather than annual leave (which usually means the annual leave is re-credited for the relevant days).

From your side as the employer, the main takeaway is: don’t guess. Have a clear internal process, confirm the evidence requirements, and apply your policy consistently.

When Does It Make Sense To Approve Annual Leave Instead Of Sick Leave?

Even where it’s legally permissible, you still need to decide what approach makes sense for your business and your team culture.

Here are some common scenarios where a request to use annual leave may arise.

1) The Employee Wants To Save Their Sick Leave

Some employees prefer to keep personal leave available “just in case” (for example, if they manage a chronic condition or have caring responsibilities).

If they request annual leave for a sick day and you approve it, make sure the request is clearly documented (even a short email trail is better than nothing) - and make sure it’s genuinely their choice, not something they were pushed into.

2) The Employee Has Exhausted Personal Leave

This is one of the most common reasons small businesses see requests for annual leave due to illness. If you approve annual leave, you should:

• ensure the employee has a sufficient annual leave balance (or clearly document if you’re approving leave in advance)
• record the leave correctly in your payroll system
• consider whether ongoing absences raise additional issues (for example, capacity concerns, medical clearance, or performance management processes)

It can also help to understand what happens to personal leave over time, including what occurs when employment ends. Our explainer on unused sick leave is useful context for employers when you’re answering employee questions about balances.

3) You Want To Keep Things Simple Operationally (But Still Compliant)

Startups often move fast, and it’s tempting to take a “whatever is easiest” approach.

The risk is that quick verbal approvals can create a workplace precedent you didn’t mean to set, especially if your business scales and you need consistency across teams and managers.

A better approach is to set a clear policy position (what you will generally approve, what you won’t, and when evidence is required), then apply it consistently.

4) Award Or Enterprise Agreement Requirements

If your employees are covered by a modern award or an enterprise agreement, there may be specific terms affecting leave processes, evidence requirements, or how different leave types interact.

This is one of the reasons we recommend not treating leave as “one size fits all” across different roles (for example, hospitality vs tech vs retail vs professional services).

How To Handle A Request To Use Annual Leave For Sick Leave (A Practical Process)

If you want to reduce risk and avoid awkward back-and-forth with staff, it helps to standardise your workflow.

Here’s a practical, employer-friendly process you can use.

Step 1: Confirm What Leave The Employee Is Requesting (And Why)

Start by clarifying whether they’re asking to:

• use annual leave instead of personal leave, even though they still have sick leave available
• use annual leave because they’ve run out of sick leave
• convert a period of annual leave into personal leave because they were sick during annual leave

Each scenario can lead to a different payroll outcome and different compliance considerations.

Step 2: Check The Employee’s Leave Balances

This sounds obvious, but it’s where many small businesses get caught out.

Before approving annual leave, check:

• their current annual leave accrual
• whether any annual leave is already booked/approved for upcoming periods
• whether you allow annual leave in advance (and if so, how you document it)

Accurate leave balances also matter when an employee resigns and you’re calculating final entitlements. If you’d like a refresher on the employer side of this, annual leave on resignation is worth reviewing.

Step 3: Apply Your Evidence Requirements Consistently

In many workplaces, employees need to provide evidence to access paid personal leave (for example, a medical certificate or statutory declaration), particularly where the absence is more than a day or falls next to weekends/public holidays.

If your employee is sick but wants to take annual leave instead, you should still consider whether evidence is needed to support the underlying absence - especially if the issue later becomes disputed (for example, if there’s disagreement about whether annual leave should be re-credited, or whether the absence was approved at all). Your award, enterprise agreement, contract, or policy may also set expectations about evidence and notice.

If you want to set clear boundaries around when evidence is required, our guide on sick days without a certificate can help you shape a policy that’s practical and reasonable.

Step 4: Confirm The Request In Writing (Keep It Simple)

You don’t need a complicated form for every decision, but you should have a written record. For example:

• the employee email or message requesting annual leave for the absence
• your written approval (or refusal, with brief reasons)
• any supporting evidence (if required)

This becomes especially important if you ever need to respond to a complaint, a Fair Work query, or an internal dispute about leave balances.

Step 5: Record The Leave Correctly In Payroll

It’s critical to record leave using the correct category. This impacts:

• the employee’s remaining annual leave and personal leave balances
• payslip accuracy
• your internal reporting and compliance record-keeping
• final pay calculations when employment ends

For many employers, annual leave payments (including loading where applicable) can also create confusion. If you want to sense-check what should be paid and how it’s generally handled, annual leave payments is a helpful reference point.

Step 6: Watch For Patterns (But Manage Them Carefully)

If you see repeated requests to use annual leave for illness, it can be a signal of something else, such as:

• a genuine health issue requiring support or adjustments
• burnout and workload pressure in the business
• a performance or attendance issue that needs a structured process

Where there are ongoing absences, it’s often worth getting tailored advice before you take action, particularly if you’re considering capacity management or disciplinary steps.

Common Employer Mistakes (And How To Avoid Them)

Most compliance issues around leave don’t come from bad intent. They come from businesses growing quickly, different managers handling leave differently, or a lack of clear documentation.

Here are common pitfalls we see, and how you can avoid them.

1) Treating Annual Leave As A “Replacement” For Personal Leave Automatically

If an employee is genuinely sick and entitled to paid personal leave, the safer default is usually to record it as personal leave (subject to notice and evidence requirements) rather than shifting it into annual leave without a clear request from the employee and a clear record.

When annual leave becomes the “default sick leave”, it can create confusion about entitlements and increase the risk of disputes later.

2) Approving Requests Inconsistently

In a startup, it’s common for founders to approve leave informally. The risk is that different people get different outcomes for similar situations, which can lead to:

• employee complaints
• cultural issues (perceptions of unfairness)
• legal risk, especially if an employee alleges adverse action or discrimination connected to illness

A clear written policy helps reduce this risk significantly.

3) Not Having The Right Employment Documents In Place

Leave entitlements largely come from the National Employment Standards (NES) and any applicable award/enterprise agreement, but your internal documents matter too, especially for setting expectations about:

• how leave is requested and approved
• when evidence is required
• who to notify and when
• what happens if an employee is sick while on annual leave

Putting the basics in place early is a smart move as you hire. This often starts with a solid Employment Contract and grows into clearer internal rules as your team expands (especially once you have managers approving leave across departments).

Many businesses also consolidate leave and attendance expectations into a Staff Handbook, so your approach is consistent and easy to roll out.

4) Allowing Annual Leave In Advance Without Clear Agreement

Some employers allow employees to “go into negative annual leave” as a goodwill gesture.

This can be workable, but it’s important to document it properly and think through:

• what happens if the employee resigns before accruing that leave back
• whether you’ll deduct any negative balance from final pay (and whether that’s permissible in the particular circumstances)
• how you’ll apply this consistently across the business

Because wage deductions and final pay can be sensitive, it’s worth getting advice before you implement a blanket approach.

How To Set A Clear Policy For Annual Leave And Sick Leave In Your Startup

If you want to grow without constant case-by-case decision-making, a clear policy position is one of the simplest ways to reduce risk.

Your policy doesn’t need to be complicated, but it should be written, communicated, and followed.

Key Policy Points To Include

As a starting point, consider covering:

• Request process: how employees request annual leave and personal leave (and who approves it).
• Notice expectations: what “as soon as practicable” means in your business when someone is sick (for example, notify their manager before start time).
• Evidence requirements: when you will require a medical certificate or statutory declaration.
• Sick during annual leave: whether and how annual leave can be reclassified as personal leave if illness occurs (including what evidence you require).
• Annual leave in advance: whether you allow negative annual leave balances, and what approval process applies.
• Record-keeping: the importance of accurate payroll records and leave balances.

Make Sure Your Documents Match How You Actually Operate

The biggest “silent risk” for startups is having policies that look good on paper but aren’t followed day-to-day.

If your managers routinely approve leave via Slack, for example, your policy should reflect an acceptable written request method (and your record-keeping should capture those approvals).

Consistency is what protects you when a situation escalates.

Key Takeaways

• In limited circumstances, annual leave can be used when an employee is sick - but annual leave and personal leave aren’t automatically interchangeable.
• Start by clarifying the scenario: an employee requesting annual leave instead of personal leave, an employee with no personal leave left, or an employee getting sick during annual leave.
• Apply a consistent process: confirm the request, check leave balances, apply notice/evidence requirements, document approvals, and record leave correctly in payroll.
• Most small business risk comes from inconsistency and poor documentation, not from the leave decision itself.
• A clear Employment Contract and internal leave policy (often in a Staff Handbook) helps your startup scale with fewer disputes and less admin stress.
