Yes, employers can legally change a casual employee’s roster in Australia. There is no set amount of notice the law universally requires, but most modern awards do specify minimum notice periods for shift changes, and some situations require a full consultation process before you can alter a regular pattern of hours. Get it wrong and you are looking at underpayment claims, adverse action complaints, or a Fair Work Commission dispute.
- There is no single notice period, it depends on your award. Most modern awards set specific notice requirements for casual shift changes, ranging from one hour to several days. If your award requires notice and you skip it, the employee may be entitled to additional pay.
- Changing a regular pattern of hours requires consultation, not just notice. If a casual works a predictable schedule, most awards require you to notify them, explain the change, and genuinely consider their response before it takes effect.
- Award minimum engagement periods still apply, even if you send a casual home early. If a casual starts their shift, most awards require you to pay a minimum number of hours regardless of how long they actually work.
- After 6 months (12 months for small businesses), eligible casuals can request to convert to permanent employment. Consistently cutting their hours after a conversion request could constitute adverse action under the Fair Work Act 2009 (Cth).
- A written Casual Employment Agreement sets clear expectations from day one. It is one of the most effective ways to reduce disputes about roster changes and hours.
Who is a casual employee in Australia?
A casual employee is someone whose employment has no firm advance commitment to continuing and indefinite work, and who receives a casual loading in place of paid leave entitlements. That is the definition under the Fair Work Act 2009 (Cth), updated from 26 August 2024 as part of the Closing Loopholes reforms.
The important change from 2024 is that the definition now looks at the practical reality of the relationship, not just what the employment contract says. If a casual employee has worked the same shifts every week for a year, that pattern is relevant evidence. It does not automatically convert them to a permanent employee, but it does affect both their rostering rights and their ability to request casual conversion.
Casual employees receive a loading, typically 25%, on top of the ordinary hourly rate to compensate for the absence of paid annual leave, personal leave, and most other leave entitlements available to permanent staff. That loading does not buy you unlimited flexibility. The rules below still apply.
Can you change a casual employee’s rostered hours?
Yes. Casual employment is built around workforce flexibility. You can offer fewer hours one week, more the next, or no shifts at all. There is no legal requirement to maintain a consistent pattern of hours week to week. This is fundamentally different from part-time or full-time employees, where changes to contracted hours require a formal process and, often, the employee’s agreement.
That said, flexibility is not the same as an unlimited right to change hours without process. Two obligations apply almost universally.
First, most modern awards include a consultation obligation. Before you change a casual’s regular roster or ordinary hours, you must notify them of the proposed change, give them information about it, and invite them to give their view on how it affects them. This applies where the casual works a regular and predictable pattern, not to irregular or sporadic casuals whose hours genuinely vary week to week.
Second, if the employee has worked a regular pattern for six months or more (12 months for small businesses with fewer than 15 employees), they may have accrued the right to request conversion to permanent employment under the Employee Choice Pathway. Dramatically reducing their hours immediately after they raise that prospect, or in response to their exercising a workplace right, can give rise to an adverse action claim. The Fair Work Ombudsman takes these seriously.
How do you change a casual roster legally?
The process depends on whether you are changing a published roster or changing a regular pattern. Both are permitted, but the steps differ.
Changing a roster before it is published
You have full discretion over shift offers before you publish a roster. You are not obliged to offer any particular number of hours, and a casual can accept or decline any shift offered. Keep a record of offers made and accepted, this is good practice and legally required under the Fair Work Act record-keeping rules (records must be kept for at least seven years).
Changing a roster after it has been published
Once a casual employee has accepted a shift and it appears on a published roster, changing or cancelling it becomes more complicated. Check your modern award. Many awards set minimum notice periods for shift changes and cancellation requirements. For example, the General Retail Industry Award 2020 requires at least one hour’s notice for a roster change; the Hospitality Industry (General) Award 2020 has its own provisions. If your award requires notice and you do not give it, the employee may be entitled to additional payments.
If you cannot find your award’s rules, the Fair Work Ombudsman’s rosters page has a searchable tool that lets you find award-specific rostering rules by industry.
Changing a regular pattern of hours
This is where most employers get into trouble. If a casual has been working regular, consistent shifts, say, every Tuesday and Thursday morning for six months, they have a regular roster in the practical sense, even if their contract says otherwise. Before you change that pattern, your award almost certainly requires you to:
- Notify the employee of the proposed change and when it will start
- Give them information about the nature of the change and why it is happening
- Invite them to share their view, including any impact on family or caring responsibilities
- Consider their view before making a final decision
The consultation process does not give the employee a veto. You can proceed with the change after genuinely considering their response. But skipping the process entirely, especially if the employee later makes an adverse action claim, puts you in a weak position with the Fair Work Commission.
How much notice does an employer have to give for a casual shift change?
There is no single answer. The notice required for a casual shift change depends on your modern award or enterprise agreement, not a universal rule in the Fair Work Act. If no award applies, the standard is “reasonable notice” based on the circumstances.
Here is how it works in practice across the most common awards:
| Award | Notice for roster change | Cancellation / short-notice rules |
|---|---|---|
| General Retail Industry Award 2020 | 7 days for regular roster changes | Can change with 1 hour’s notice in specific circumstances (e.g. emergency) |
| Hospitality Industry (General) Award 2020 | 7 days where practicable | Shorter notice permitted by agreement or in unforeseen circumstances |
| Fast Food Industry Award 2010 | 7 days where practicable | Shorter notice if agreed with employee |
| Clerks Private Sector Award 2020 | 7 days for changes to regular roster | Changes with less notice may attract penalty rates |
| Hair and Beauty Industry Award 2010 | 7 days where practicable | Short-notice changes may require employee agreement |
The 7-day figure appears frequently across awards, but it is not universal and not in the Fair Work Act itself. What the Fair Work Act does require is that employers with modern award coverage follow the consultation obligations in that award when changing regular rosters or ordinary hours.
For casual employees with irregular or sporadic hours, the notice obligation is lower. The formal consultation provisions in most awards only apply where the casual has a regular and predictable pattern of work. One-off shift changes for genuinely irregular casuals generally do not trigger the same notice requirements.
If you are not covered by a modern award, or you are unsure which one applies, the Fair Work Ombudsman’s Pay and Conditions Tool (PACT) can identify the applicable award for your industry and role. Alternatively, an employment lawyer can confirm your obligations in under 30 minutes.
What are minimum engagement periods, and do they apply to casuals?
Yes, and this is the most commonly misunderstood aspect of casual rostering. Most modern awards set a minimum engagement period per shift, meaning that once a casual employee arrives and starts work, you must pay them for a minimum number of hours regardless of how long they actually work.
Common minimum engagement periods include:
| Award | Minimum engagement |
|---|---|
| General Retail Industry Award 2020 | 3 hours |
| Hospitality Industry (General) Award 2020 | 2 hours |
| Fast Food Industry Award 2010 | 2 hours |
| Clerks Private Sector Award 2020 | 3 hours |
| Hair and Beauty Industry Award 2010 | 3 hours |
In practice, this means: if you roster a casual for a four-hour shift, business gets quiet, and you send them home after 90 minutes, you still owe them the three-hour minimum under the relevant award. This applies even if they agree to leave early. The minimum engagement is a floor, not a default that can be contracted away.
The Fair Work Ombudsman regularly finds businesses that have underpaid casuals by not accounting for minimum engagement periods, particularly in retail and hospitality. If you are in the habit of sending casual staff home early when things are quiet, check your award’s minimum engagement provisions before you do it again.
When does a regular roster trigger permanent employment rights?
This is the question employers ask most often after a long-term casual starts pushing back on roster changes, and it is also where the biggest legal risk sits.
Since 26 August 2024, the definition of casual employment turns on whether there is “no firm advance commitment to continuing and indefinite work, considering the real substance, practical reality and true nature of the relationship.” Regular, predictable rostering is one of the factors the Fair Work Commission can weigh when assessing whether that commitment actually exists.
A consistent roster does not automatically convert someone to a permanent employee. But it does open the door to the Employee Choice Pathway: after six months of employment (12 months for small businesses), eligible casuals can give written notice that they believe they no longer meet the casual definition and want to convert to permanent employment. Once you receive that notice, you must respond in writing within 21 days, accepting the conversion or providing specific grounds for refusal.
Valid grounds for refusal include that the employee still meets the casual definition or there are fair and reasonable operational grounds for refusal (for example, significant changes to work organisation would be required). “I just prefer casuals” is not valid. If in doubt, get advice before you refuse, a poorly worded refusal can become a Fair Work Commission dispute.
A separate obligation applies to non-small-business employers: you must assess long-term casuals and proactively offer conversion where eligible. Check your award or agreement for the specific timing requirements.
What is the Casual Employment Information Statement, and who needs one?
From 26 August 2024, all employers must provide the Casual Employment Information Statement (CEIS) to casual employees. The CEIS is a Fair Work document that explains casuals’ rights and entitlements, including the right to request conversion.
You must provide the CEIS to every new casual employee before or as soon as possible after they start work. You must also provide it at intervals during the employment: for non-small businesses, after 6 and 12 months of employment and annually after that; for small businesses, after 12 months. You can download the current CEIS directly from the Fair Work Ombudsman’s website.
If you do not provide the CEIS when required, that is a breach of the National Employment Standards, not a trivial paperwork error. Civil penalties for contraventions of the Fair Work Act can reach $93,900 for an individual and $469,500 for a body corporate.
Can roster changes ever be unlawful?
Yes. Three scenarios make roster changes unlawful regardless of the casual flexibility principle.
Adverse action. Under the general protections provisions of the Fair Work Act, you cannot take adverse action against an employee for exercising a workplace right. Reducing a casual’s hours because they made a complaint to Fair Work, requested a conversion to permanent employment, or took unpaid carer’s leave is adverse action. The burden of proof reverses in these cases, you have to show the reason for the roster change was not related to the protected activity.
Discrimination. Roster changes that disproportionately affect employees with protected attributes, gender, age, carer status, disability, race, religion, can breach the anti-discrimination protections that apply to all employees including casuals. A pattern of consistently reducing hours for employees with young children or religious observance requirements is a live risk.
Sham contracting. If you classify a worker as casual to avoid leave entitlements and permanent employment obligations, while providing them with a predictable, ongoing pattern of work, that is sham contracting. Fair Work inspectors investigate these arrangements actively. The risk is not just a penalty, it is also liability for back-pay of leave entitlements for the entire period.
What Lawpath employment lawyers see in practice
Across consultations on employment matters, our lawyers regularly see a few patterns that do not show up in the standard Fair Work guidance.
The most common mistake is employers cutting a casual’s hours sharply without any communication, and then finding out months later that the employee filed an adverse action complaint at around the same time as the hours were cut. The timing alone creates a connection that is hard to explain away, even if the business reason was legitimate. Document the business reason for any significant roster reduction at the time you make the decision.
A second pattern we see consistently: employers who have not checked their modern award in years. Award provisions on minimum engagement, notice for roster changes, and consultation obligations are updated regularly. What was true in 2018 or 2020 may not be the same now. If your employment contract or casual agreement pre-dates the 2024 Closing Loopholes changes, it is worth reviewing.
Third, there is a genuine misunderstanding about what “casual” means for unfair dismissal. After 12 months of regular and systematic employment, a casual may have access to unfair dismissal protections under the Fair Work Act, even though they are on a casual contract. This means “I’ll just stop offering them shifts” is not always a clean exit strategy for long-term casuals. Get advice before you make that call.
What should a casual employment agreement include?
A well-drafted Casual Employment Agreement is your first line of protection here. At minimum, it should clearly state that the employment is casual in nature, that there is no guarantee of hours, and that shift offers are made at the employer’s discretion. That language reinforces the absence of a firm advance commitment, which is the legal test for casual status.
It should also reference the applicable modern award (or confirm the award does not apply and explain what minimum entitlements apply instead), include the casual loading percentage, and set out how roster changes and shift cancellations will be communicated.
If you are rostering a casual employee on what is expected to be a regular basis, address that directly in the agreement. Confirm that while hours may be similar week to week, that pattern does not constitute a commitment to ongoing hours, and that the arrangement is reviewable at any time. That will not override the law, if the practical reality becomes an ongoing commitment, the law will look at the reality, but it sets expectations and reduces disputes.
You also need to provide the CEIS at the time of engagement. Include a signed acknowledgment so you have a record.
Casual roster change checklist
Before you change a casual employee’s roster, work through this checklist:
- Check your modern award. Find the minimum engagement period, notice requirements for roster changes, and any consultation obligations that apply to your industry.
- Assess whether the employee works a regular pattern. If yes, the consultation obligation under your award almost certainly applies before you change their regular hours.
- Consult before you change. Notify the employee of the proposed change, give them the reason, and invite their response in writing. Keep a record.
- Check your reason for the change. Is it a legitimate business reason? Document it now, not later.
- Review the timing. If the employee has recently made a complaint, requested conversion, or exercised any other workplace right, the timing of a roster reduction will be scrutinised. Take legal advice.
- Confirm your CEIS obligations. Is the CEIS up to date? Have you provided it at the required intervals?
- Check whether the employee may have unfair dismissal access. If they have worked regular and systematic hours for more than 12 months, get advice before you effectively stop rostering them.
Frequently asked questions
Can I reduce a casual employee’s hours without notice?
For one-off shift changes, the notice required depends on your modern award. Many awards allow short-notice changes in genuine emergencies. For changes to a regular pattern of hours, most awards require a consultation process before the change takes effect. Reducing hours without any notice or consultation when the employee works a predictable schedule is a breach of the consultation provisions in most awards.
Can I stop offering shifts to a casual employee altogether?
Generally yes, you are not obliged to offer any shifts to a casual employee. But if the employee has worked regular and systematic hours for 12 months or more, they may have access to unfair dismissal protections. Stopping shifts entirely without a legitimate reason, or in response to the employee exercising a workplace right, may constitute constructive dismissal or adverse action. Get legal advice before ceasing to roster a long-term regular casual.
What happens if I change a casual’s roster and they refuse to accept the change?
A casual employee can decline a shift offer. That is one of the defining features of casual employment. If you change published shifts, the employee may decline the new arrangement, particularly if they had accepted the original shift. You cannot penalise a casual for declining a shift (for example, by never offering them shifts again), as this could constitute adverse action.
Does a regular casual roster mean the employee becomes permanent?
Not automatically. A regular roster is one of the factors the Fair Work Commission considers when assessing the practical nature of the employment relationship under the 2024 definition of casual employment. It does not by itself convert a casual to permanent, but it may open the door to the Employee Choice Pathway, where the employee can give notice that they believe they no longer meet the casual definition.
Can I change a casual’s roster to avoid them reaching 6 months of employment?
No. Deliberately reducing or ceasing to offer shifts in order to prevent a casual from reaching the 6-month threshold (and becoming eligible for the Employee Choice Pathway) is likely to be adverse action under the general protections provisions of the Fair Work Act. The Fair Work Commission has jurisdiction to deal with these disputes, and penalties are significant.
Do casual employees have to be given a reason for a roster change?
If the change affects a regular pattern of hours, your modern award’s consultation provisions will require you to provide information about the nature of the change and invite the employee’s response. For one-off changes, the formal consultation obligation may not apply, but communicating the reason is always good practice and reduces disputes.
What if I send a casual home early, do I still have to pay them?
Yes, in most cases. Modern awards set minimum engagement periods for casual employees, typically two to three hours depending on the industry. If a casual starts their shift and you send them home before the minimum engagement period is up, you must pay them for the full minimum period. This applies even if the employee agrees to leave early.
What is the Casual Employment Information Statement?
The CEIS is a Fair Work document that employers must give to all casual employees. It explains casual entitlements and the process for requesting conversion to permanent employment. From 26 August 2024, the CEIS must be given to new casuals at the start of employment, and to existing casuals at specified intervals (after 6 months, 12 months, and annually after that for non-small businesses). Failing to provide it is a breach of the National Employment Standards.
Where to from here
Changing a casual roster is legal, but the rules around how and when you do it have more substance than most employers realise. The 2024 Closing Loopholes changes shifted the focus to the practical reality of the employment arrangement, not just what a contract says. That means regular patterns of hours matter more now than they did before. So does documentation.
If you have casual employees who have been working a consistent pattern, now is a good time to review your employment agreements, your CEIS obligations, and your modern award’s rostering provisions. A bit of housekeeping now is far cheaper than a Fair Work Commission dispute later.
