Can I Change a Roster Last Minute in Australia — or Do I Need to Give Notice?

7 Apr 2026 By Fitz HR 6 min read

It's Saturday morning. You're overstaffed, or you're short a person and need someone in now. You change the roster. Simple, right? Not always — and getting this wrong is one of the most common sources of underpayment claims in hospitality. The answer depends on who you're asking and what their contract says.

It Depends on Employment Type

The rules around roster changes in Australian hospitality are not one-size-fits-all. Most venue owners assume they have full flexibility — they don't. The type of employment is everything. Casual employees, part-time employees, and full-time employees all have different entitlements — and getting this wrong is one of the most common sources of underpayment and Award breaches.

Here's how the rules break down in practice:

Employment Type Can you change rosters last minute? Key obligations
Casual Generally yes — no guaranteed hours 2-hour minimum per shift if called in. If cancelled before starting, no pay required.
Part-time With reasonable notice, yes. Unilaterally removing agreed hours is a breach. 3-hour minimum engagement per shift. Must pay minimum even if sent home early.
Full-time Operational changes with notice are generally lawful. Significant changes to agreed hours require agreement. 7.6 hours per day / 38 hours per week. Changes outside this are overtime.

The Part-Time Employee Problem

Part-time employees under the Hospitality Industry (General) Award MA000009 have agreed hours set out in their employment agreement. These are guaranteed. You cannot unilaterally reduce them without the employee's agreement.

The Award requires that any change to a part-time employee's regular pattern of hours — days, start times, finish times — be agreed in writing. A text message or verbal agreement in a pinch is not ideal, but the key word is "agreed" — you cannot simply impose the change.

A common scenario: a quiet lunch service leads to a part-time employee being sent home after 1 hour. It feels reasonable operationally — but legally, you still owe them 3 hours' pay. This is one of the most common underpayment claims the Fair Work Ombudsman sees in hospitality, and it catches venue owners who didn't know the minimum engagement rule.

The 3-Hour Rule — Part-Time

If a part-time employee comes in and you send them home before 3 hours, you still pay them for 3 hours at their full rate. This is a minimum engagement requirement and it applies even if you had a genuine operational reason for the early finish.

Casual Employees — More Flexibility, Still Rules

Casual employees are engaged on an as-needed basis and have no guaranteed hours — so you have considerably more flexibility to change, reduce, or cancel shifts. However, there are still obligations:

Minimum engagement

If you call a casual in for a shift, you must pay them for a minimum of 2 hours — even if you only needed them for 45 minutes. Once they show up, the minimum engagement applies.

Cancellation before the shift starts

If you cancel a casual's shift before they have left home, no pay is required. If they have already left home or are on their way, a payment for reasonable travel costs or time may be appropriate — though the Award does not specifically prescribe this.

Casual conversion implications

If you regularly roster a casual on the same days and times over a long period, they may be eligible for casual conversion to part-time employment. Once converted, the part-time rules apply and that flexibility is reduced.

What About the Right to Disconnect?

Since 2024, under the Fair Work Act 2009 (Cth), employees have a legislated right to disconnect — to refuse to monitor or respond to contact from their employer outside of working hours, unless that refusal is unreasonable. This is a shift many employers haven't caught up with yet — and it directly affects how last-minute roster changes are communicated.

Sending a roster change via WhatsApp at 9pm for a 6am shift the next morning is the kind of contact that employees can now lawfully decline to engage with. This doesn't mean you can't send the message — but you can no longer assume receipt equals acknowledgement, and you cannot discipline an employee for not responding to after-hours contact about a last-minute change.

What Not to Do with Rosters

These are the mistakes that turn a routine roster change into a wage claim:

✗
Don't send a part-time employee home early without paying the 3-hour minimum. Even if you only needed them for 45 minutes, the minimum engagement applies once they arrive. This is the most common roster-related underpayment in hospitality.
✗
Don't assume a verbal agreement is enough for a part-time change. The Hospitality Award requires changes to a part-time employee's regular hours to be agreed in writing. A text is better than nothing — but get something documented.
✗
Don't systematically reduce a part-time employee's hours without their agreement. Sustained reduction of agreed hours without consent can amount to a constructive dismissal claim — even if the employee keeps turning up.
✗
Don't expect a response to after-hours roster messages. Since 2024, the right to disconnect means employees can lawfully ignore work contact outside their rostered hours. Plan roster changes during business hours where possible.

Best Practice for Roster Changes

Give as much notice as possible. The Award references "reasonable notice" — in practice, 7 days is the standard for planned changes. For operational reasons, 24-48 hours is generally accepted when it can't be avoided.

Get agreement for part-time changes. A quick written confirmation ("Happy for the change on Saturday?") is far better than an assumed yes, especially if the employee later disputes it.

Document changes. Keep a record of any roster changes, who agreed, and when. This matters if a dispute arises about hours worked or entitlements owed. If a roster change leads to conflict or complaints, how you respond matters — especially if an employee raises Fair Work. And if the situation escalates to termination, make sure you understand what you can and can't do in the moment.

Unilaterally cutting a part-time employee's hours without agreement is a contract breach — it can amount to a constructive dismissal claim if it's severe or sustained enough. A part-time employee who has had their guaranteed hours systematically reduced may have grounds to argue the employment relationship has been fundamentally changed without consent.

Frequently Asked Questions

Can I change a roster last minute in Australia?
It depends on the employee type. Casuals can generally have rosters changed without notice since they have no guaranteed hours. Part-time employees must receive reasonable notice and roster changes should be agreed in writing. If you send a part-time employee home early, you must still pay the 3-hour minimum engagement.
How much notice do I need to give to change a roster?
The Hospitality Award requires reasonable notice of roster changes. Where practicable, 7 days is the standard. For genuine operational reasons, shorter notice may be acceptable — but the employee's agreement is recommended wherever possible, especially for part-time staff.
Do I have to pay a part-time employee if I send them home early?
Yes. Under the Hospitality Award, part-time employees have a minimum engagement of 3 hours. If you send them home before they have worked 3 hours, you must still pay them for the full 3-hour minimum — even if they only worked 1 hour.
Can I cancel a casual's shift last minute without paying them?
If a casual employee has not yet started their shift, you can generally cancel it without payment. However, if they have already started work, they are entitled to be paid for time worked and the 2-hour minimum engagement applies.
What is the right to disconnect and does it affect rosters?
The right to disconnect gives employees the right to refuse to respond to work contact outside working hours. This means employees can now lawfully choose not to respond to last-minute roster change messages sent after hours — and you cannot discipline them for it.
What is the minimum shift for casual employees in hospitality?
Under the Hospitality Award, casual employees are entitled to a minimum engagement of 2 hours per shift. If you ask a casual to come in and they work less than 2 hours, you must still pay them for 2 hours at the applicable casual rate.

This is one of the most misunderstood obligations in hospitality HR. Most rostering disputes don't come from bad intentions — they come from not knowing the rule before making the call.
