Sick Leave For Casual Workers In Victoria: Employer Requirements

Hiring casual staff can give your business the flexibility to manage fluctuating demand, extended trading hours, and seasonal peaks.

But when a casual worker calls in sick, things can get confusing fast - especially if you’re trying to balance fairness, rostering needs, and your legal obligations.

This guide explains how sick leave for casual workers in Victoria works in practice, what the National Employment Standards (NES) say, what to check in awards and enterprise agreements, and how you can set up simple processes that reduce payroll mistakes and workplace disputes.

Are Casual Employees Entitled To Paid Sick Leave In Victoria?

For most small businesses, the key point is this:

• Casual employees generally do not get paid sick leave (paid personal/carer’s leave) under the NES.

Paid personal/carer’s leave is an entitlement for full-time and part-time employees. It accrues over time and can be used when an employee is unfit for work due to illness or injury, or to provide care to an immediate family or household member.

Because casuals don’t accrue paid leave, the usual expectation is:

• if a casual is sick and can’t work their shift, the shift is typically unpaid, and
• you’ll need to manage the operational impact (finding cover, adjusting rosters, etc.).

That said, managing sick leave for casual workers in Victoria can still involve legal obligations and risks for employers - particularly around:

• unpaid leave entitlements that casuals do have (e.g. unpaid carer’s leave),
• award or enterprise agreement rules,
• casual status and casual conversion (including where an employee may not be a “true casual” under the Fair Work Act definition), and
• general protections and discrimination laws (for example, you can’t take adverse action against someone for exercising a workplace right, and illness/injury can raise separate legal risks depending on the circumstances).

Important Reminder: Victoria Vs Federal Rules

Most Victorian businesses are covered by the national workplace relations system (Fair Work). That means your starting point is usually the Fair Work Act and the NES, rather than state-based leave rules.

However, there are some Victorian employers and employees who may fall outside the national system (for example, certain state public sector roles). If you’re not sure which system applies to your workplace, it’s worth checking early, because the rules can differ.

When Can A Casual Still Be Paid (Or Get Leave) If They’re Sick?

Even though casuals usually don’t receive paid sick leave, there are several situations where time off can still be relevant, and sometimes paid.

1) Unpaid Carer’s Leave (Casuals Can Access This)

Casual employees can access unpaid carer’s leave under the NES in certain circumstances (for example, if they need to care for an immediate family or household member who is ill or injured).

This is one reason employers should still have a clear “sick and carer’s leave” process for casuals, even where the absence won’t be paid.

2) Unpaid Compassionate Leave (Including Casuals)

Casual employees are also generally entitled to unpaid compassionate leave under the NES in qualifying circumstances.

From an employer perspective, you’ll still need a consistent way to:

• record the absence correctly,
• request evidence when appropriate, and
• manage coverage without penalising someone for accessing their entitlements.

3) Paid Family And Domestic Violence (FDV) Leave

In Australia, paid family and domestic violence leave under the NES applies to employees, including casual employees, when they need to do something to deal with the impact of family and domestic violence and it’s impractical to do so outside ordinary work hours.

This is a separate entitlement to “sick leave”, but it often comes up in the same operational context (short-notice absences, evidence requests, privacy concerns, and payroll processing).

4) Your Award Or Enterprise Agreement Might Add Extra Entitlements

While the NES is the baseline, your employee’s modern award or enterprise agreement may include additional rules that affect casual absences, such as:

• minimum engagement periods,
• notice requirements,
• shift cancellation rules, and
• process requirements for providing evidence.

These rules don’t always create “paid sick leave” for casuals, but they can affect what you can do when a casual can’t attend work (and what you must pay if you cancel or change shifts).

5) You Might Choose To Pay Anyway (Discretionary Payments)

Some employers choose to pay a casual for a missed shift as a goodwill gesture (for example, if they have been reliable and you want to support them through a short illness).

You can generally do this, but it’s important to be consistent and careful about setting expectations. If you regularly pay “sick leave” to casuals without clear rules, you can accidentally create:

• employee relations issues (claims of unfairness), and/or
• a contractual expectation over time.

If you want the option to do discretionary payments, consider documenting it in a policy as “at management discretion” and not an automatic entitlement.

How Should You Manage Sick Leave Requests From Casuals In Victoria?

The simplest way to reduce risk is to treat casual absences as a process, not a scramble.

Here’s a practical approach many small businesses use to manage sick leave for casual workers in Victoria in a consistent, legally safer way.

Step 1: Ask For Notice As Early As Possible

You can require casual workers to notify you they can’t attend their shift as soon as practicable.

To make this workable, set a clear expectation in writing, such as:

• who they should contact (manager on duty, roster coordinator),
• how they should contact you (call vs text vs app message), and
• the minimum information needed (e.g. “I’m unwell and can’t work today”).

Be careful not to demand detailed medical information. Usually, you only need to know they’re unfit for work.

Step 2: Confirm Whether It’s Sick Leave, Carer’s Leave, Or Something Else

From a payroll and compliance standpoint, it matters whether the absence is:

• the casual worker is unwell (typically an unpaid absence),
• they’re caring for someone else (potentially unpaid carer’s leave), or
• it relates to family and domestic violence (potentially paid FDV leave).

You don’t need to interrogate the employee, but you should ensure the absence is classified correctly in your records.

Step 3: Decide Whether Evidence Is Reasonable For That Shift

Many businesses only request evidence when:

• the absence is frequent or patterned (e.g. every Saturday),
• the worker was rostered for a critical shift,
• there’s a dispute about whether the employee was genuinely unfit, or
• the worker is requesting a paid entitlement (like FDV leave) or a specific form of leave.

Your approach should be reasonable and applied consistently.

Step 4: Record The Absence Properly (Even If It’s Unpaid)

Even if no payment is made, you should still record:

• the rostered shift,
• the reason code (sick / carer’s / other approved leave),
• any evidence provided, and
• who approved the absence and when.

Good records are a simple way to protect your business if there’s ever a disagreement later about what happened and why.

Step 5: Use Clear Employment Documentation

A lot of conflict about sick leave for casual workers in Victoria is really conflict about expectations.

A well-drafted Employment Contract can help by setting out practical rules around:

• casual nature of employment,
• rostering and availability,
• notification requirements for absences, and
• what happens when shifts can’t be worked.

Medical Certificates, Evidence Requests, And Privacy: Getting The Balance Right

Evidence is one of the most sensitive parts of managing sick leave for casual workers in Victoria.

On the one hand, you need to manage operational risk and reduce fake sickies. On the other hand, employees have privacy rights and you must avoid unreasonable demands.

When Can You Ask For Evidence?

As a general principle, you can ask for evidence that would satisfy a reasonable person that the employee is unfit for work (or needed leave for the relevant reason).

Evidence might include:

• a medical certificate,
• a statutory declaration, or
• other documentation depending on the circumstances.

In practice, many employers ask for medical certificates in higher-risk situations. If you’re unsure what’s reasonable, it can help to understand how medical certificates work for casual staff specifically.

Do Casuals Need A Medical Certificate For One Day Off?

There’s no universal “one day = no certificate” rule in every workplace. What matters is what’s reasonable, plus any award, enterprise agreement, or workplace policy that applies.

Many small businesses choose a practical rule (for example, “a certificate is required for 2+ consecutive shifts, or where the absence is immediately before/after a public holiday”). If you do this, apply it consistently.

It’s also common for employees to ask about sick days without a certificate. From an employer perspective, the key is to make your expectations clear and reasonable, and to document them.

Can You Accept Statutory Declarations?

Yes, in many cases a statutory declaration can be acceptable evidence, depending on the situation and what’s required under the relevant industrial instrument.

If you want a simple, compliant format, a statutory declaration can be an option when a medical certificate isn’t available (for example, if the illness was short and the employee couldn’t get an appointment).

How Much Medical Detail Can You Ask For?

Generally, you should avoid requesting specific diagnoses or sensitive details unless there’s a genuine need.

Where you have concerns about fitness for duties (for example, operating machinery or returning after a significant illness), you may be able to request clearance. The safest approach is to only ask for what’s reasonably necessary and relevant to the role - which is why it helps to understand medical clearance rules in an employment context.

Storing Evidence And Maintaining Confidentiality

When you receive medical certificates, stat decs, or other sensitive documents, treat them as confidential employee records. Limit access to managers who genuinely need to know, and store them securely.

This isn’t just good practice - it helps build trust and reduces the risk of privacy complaints.

Common Compliance Risks For Employers Managing Casual Sick Leave In Victoria

Most disputes about sick leave for casual workers in Victoria don’t happen because an employer is trying to do the wrong thing. They happen because the rules weren’t clear, or the employer applied them inconsistently under pressure.

Here are some common risk areas to watch for.

1) Getting Casual Status Wrong (Including Casual Conversion Issues)

Under the Fair Work Act, whether someone is a casual employee generally depends on whether the employment was offered and accepted without a firm advance commitment to continuing and indefinite work (and what the contract and offer say about things like ongoing work, agreed patterns, and the employer’s ability to offer/withdraw shifts).

If a worker is engaged as a “casual” on paper, but the arrangement actually involves a firm advance commitment or should have been treated as ongoing employment, this can create disputes about entitlements and processes (including casual conversion obligations and, in some cases, backpay risks).

If you’re relying heavily on casuals for stable, long-term roles, it’s worth getting advice early and making sure your contracts, rostering practices, and payroll treatment are aligned.

2) Adverse Action Or Discrimination Issues

Even if a casual isn’t entitled to paid sick leave, you still need to be careful about how you respond when they’re unwell.

Examples of risky behaviour include:

• removing someone from future rosters because they exercised a workplace right (for example, taking unpaid carer’s leave, compassionate leave, or paid FDV leave),
• taking action against a worker for a temporary absence due to illness or injury where protections apply (often linked to notice and evidence requirements), or
• making negative comments about illness or injury that could link to disability discrimination.

It’s fine to manage performance, attendance patterns, and genuine operational needs - but do it based on evidence and fair process, and document the reasons for rostering and staffing decisions.

3) Inconsistent Evidence Requests

If you only ask certain workers for medical certificates (for example, younger staff, or staff from a particular background), you can create a perception of unfairness - and potentially a legal risk.

Consistency is one of the best protections you have. A simple written policy (and training for supervisors) helps a lot here.

4) Not Having A Plan When Leave Entitlements Run Out (Or Don’t Apply)

Sometimes casual workers will have extended time away from work due to illness or injury. Even though paid sick leave may not apply, you’ll still need to manage:

• operational coverage,
• ongoing communication, and
• whether shifts continue to be offered.

If the situation becomes more complex (especially where the worker may be moving into longer-term absence patterns), it can help to understand how employers can approach leave when entitlements run out - and how to document decisions carefully.

5) Confusion Around Shift Changes And Cancellations

When a casual calls in sick, you’ll often need to cancel or reallocate a shift at short notice. Depending on the award and the facts, there may be minimum notice rules or payment obligations when shifts are changed.

This is one area where it’s worth checking the employee’s award and keeping a written roster change process so you can show what notice was given and why.

Key Takeaways

• Sick leave for casual workers in Victoria usually means unpaid time off, because casual employees generally don’t accrue paid personal/carer’s leave under the NES.
• Casuals can still have important leave-related rights (including unpaid carer’s leave, unpaid compassionate leave, and paid family and domestic violence leave in qualifying circumstances).
• Award and enterprise agreement terms can affect how you manage absences (including rostering, evidence requirements, and shift changes), so it’s important to check what applies to your workplace.
• Having a consistent process for notifications, evidence requests, and record keeping helps you avoid payroll errors and reduces the chance of disputes.
• Be cautious about casual status, casual conversion obligations, adverse action risks, and inconsistent treatment - these are common compliance problems for small businesses managing casual staff.
• Clear documentation (including a well-drafted casual employment contract and practical workplace policies) is one of the best ways to set expectations and protect your business.
