Rostering is how you match your people to your workload – and when demand changes, your roster usually needs to change with it. Whether you’re running a café, a clinic or a retail store, you’ll sometimes need to add, move or reduce shifts at short notice.
The tricky part is making those changes lawfully and fairly. In Australia, the Fair Work Act, Modern Awards and Enterprise Agreements set rules around consultation, notice and how you handle changes to regular hours. If you don’t follow the process, you can quickly find yourself dealing with complaints, penalties or avoidable disputes.
The good news: with a clear process and the right documents, you can change employee rosters confidently while staying compliant. This guide breaks down what counts as a roster change, what the law requires, step-by-step processes, and common pitfalls to avoid – all in plain English.
What Counts As A Roster Change Under Australian Law?
A roster change is any adjustment to an employee’s usual pattern of work. This can include:
- Changing start or finish times
- Adding, removing or swapping shifts
- Altering the days someone works
- Introducing or removing rostered days off
- Varying agreed ordinary hours for part-time employees
Roster changes can affect full-time, part-time and casual staff (your obligations differ between these categories). In general, you’ll need to look at three places to understand the rules that apply to you:
- The Fair Work Act 2009 (Cth) and the National Employment Standards (NES)
- The relevant Modern Award or Enterprise Agreement
- The employee’s contract and your workplace policies
Awards and agreements set the practical rostering rules (like notice, posting rosters, minimum engagements and consultation). The Fair Work Act requires awards and agreements to include a consultation term for changes to regular rosters or ordinary hours.
Can You Change Rosters? The Rules (Fair Work, Awards And Agreements)
Yes – employers can change rosters, but there are process requirements you need to follow. The specifics differ by industry and instrument, so always check the applicable Award or Enterprise Agreement for your staff. A helpful starting point is understanding the common building blocks across most instruments.
Consultation About Changes to Regular Rosters or Ordinary Hours
Modern Awards and Enterprise Agreements include a consultation term requiring you to:
- Inform affected employees about the proposed change
- Provide information about the likely effects on them
- Invite them to give their views (including any impact on them)
- Consider their views before making a final decision
Consultation doesn’t mean you need unanimous agreement, but you do need to genuinely listen and consider employee feedback before confirming the change.
Notice And How Rosters Are Posted
Many Awards require rosters to be posted a set period in advance (for example, at least 7 days in some industries), and only changed by mutual agreement or where there are unforeseen circumstances. Others set different timelines or methods. There isn’t a single “standard” notice period that applies to every workplace.
If you want a deeper dive into the moving parts (like minimum engagements, rules about consecutive days off and roster posting methods), it’s worth reviewing the legal requirements for employee rostering in Australia or getting advice on your Award.
Reasonableness, Emergencies And Mutual Agreement
- Mutual agreement: Many Awards allow changes by agreement. If you and the employee agree to an earlier start or a swapped shift, put that agreement in writing.
- Unforeseen circumstances: Some instruments allow short-notice changes to deal with things like sudden unplanned absences or emergencies.
- Reasonableness and fairness: Your approach must be reasonable and non-discriminatory. Avoid using roster changes to disadvantage someone because they’ve exercised a workplace right.
Minimum Notice For Shift Changes Isn’t One-Size-Fits-All
Minimum notice for changing or cancelling a shift depends on the Award or Agreement. Some set specific timeframes (and even compensation if notice isn’t met). A practical overview of these concepts is in our guide to the minimum notice for shift changes.
Specific Considerations For Casual, Part-Time And Full-Time Employees
Your obligations change depending on employment type.
Casual Employees
Casuals don’t have a firm advance commitment to ongoing work, so rostering is generally more flexible. However, risks arise if casuals develop a regular and systematic pattern and you cut or cancel shifts abruptly without following Award rules.
- Check your Award for minimum engagement periods and short-notice cancellation rules.
- If a shift is already accepted, treat cancellations carefully – a clear, fair process helps avoid disputes.
- Where casuals have an established pattern, consultation and reasonable notice are still good practice.
Common questions about casual rostering, including when someone can say no to a shift or how much notice is expected, are covered in our resources on notice requirements for casual employees and whether casual employees can refuse shifts. If you sometimes need to cancel work altogether, align your approach with a clear shift cancellation policy.
Part-Time Employees
Part-time staff usually have agreed ordinary hours (days/times) set out in writing. Awards often require you to document agreed variations. Changing those agreed hours typically triggers the consultation term and Award-specific rules. If you need ongoing flexibility, consider whether the written pattern is still fit for purpose and update it by agreement.
Full-Time Employees
Full-timers have ordinary hours capped by the Award or Agreement and the NES. You can typically move hours within span-of-hours rules and roster patterns, but you must consult about changes to regular rosters or ordinary hours, comply with rest breaks and respect any applicable notice or posting rules.
Step-By-Step: How To Change An Employee Roster Lawfully
Use this practical process to manage changes with low risk and high trust.
1) Check Your Instruments And Contracts
Identify the relevant Award or Enterprise Agreement, then read the clauses on rosters, posting timelines, minimum engagements, penalties, and consultation. Review the employee’s contract for hours, rostering provisions and any flexibility clauses. If your contracts need an update, consider issuing a tailored Employment Contract that aligns with your rostering practices.
2) Map The Proposed Change And Why It’s Needed
Write down what will change (days, times, duration, start date) and why (operational need, staffing changes, new trading hours). A short note helps keep consultation focused and consistent across your team.
3) Consult With Affected Employees
Share the proposal in writing. Explain the likely effects, invite feedback, and give a reasonable window for responses (taking into account Award timelines). Consider any alternatives or adjustments (for example, childcare, study or transport constraints). Document the discussion and the outcome.
4) Confirm The Final Decision And Issue The Roster
Once you’ve considered feedback, make your decision and confirm it in writing. Update the roster through your usual method (noticeboard, system, app) and ensure it’s posted within Award timeframes. If you’re making a permanent variation to a part-time employee’s agreed pattern, capture that agreement in writing.
5) Pay Correctly If The Change Triggers Different Entitlements
If the change leads to overtime, penalties, allowances or meal breaks, make sure your payroll calculates these correctly. If you need a refresher, revisit how penalty rates and overtime work under your Award.
6) Keep Records And Update Policies
Retain copies of notices, consultation notes and the final roster. If rostering changes are common in your business, a clear policy within your Staff Handbook can set expectations and standardise your process. For thorny or high-risk scenarios, it can be worth speaking with an Employment Lawyer.
Other Compliance To Keep In Mind When Rostering
Roster compliance overlaps with several other employment law requirements.
- Breaks and rest: Ensure you meet your Award rules and NES limits on maximum weekly hours and provide the right meal and rest breaks. If you need a refresher, our overview of Fair Work breaks can help.
- Minimum engagements: Many Awards require a minimum number of hours per shift (particularly for casuals and part-timers).
- Split shifts and spans of hours: Awards often restrict when shifts can be worked and when split shifts are allowed to avoid unreasonable patterns.
- Anti-discrimination and adverse action: Avoid using roster changes to disadvantage someone because of a protected attribute or because they raised a workplace concern.
- Record-keeping and payslips: Keep accurate records of hours, rosters and pay. This is essential if the Fair Work Ombudsman ever reviews your workplace.
- Stand downs vs. roster reductions: Standing down employees has narrow legal criteria under the Fair Work Act. Don’t rely on “stand down” to manage demand dips unless you meet those criteria – consider lawful roster adjustments instead.
If you’re often juggling last-minute changes, it can help to do an internal audit against the legal requirements for employee rostering and tighten your processes.
Common Pitfalls And How To Avoid Them
- Treating “7 days’ notice” as universal: Notice and posting rules differ by Award. Always check the instrument that applies to your team.
- Skipping consultation: You must consult about changes to regular rosters or ordinary hours. A short written consultation process helps you comply and builds goodwill.
- Changing part-time agreed hours informally: Capture variations to part-time patterns in writing to stay aligned with Award requirements.
- Forgetting minimum engagements: Short-notice changes that dip below minimum hours can lead to underpayments.
- Underpaying penalties or overtime: Roster changes can trigger higher rates. Double-check payroll settings when you shift patterns.
- Poor documentation: If there’s a dispute, well-kept notes, emails and rosters are your best defence.
- No clear policy: Without a policy, managers handle changes differently. A simple written process improves consistency and compliance.
Key Takeaways
- You can change employee rosters in Australia, but you need to follow the consultation term in your Award or Agreement and meet any posting/notice rules.
- There is no single notice period that applies to all workplaces – check your instrument for roster timelines, minimum engagements and when changes are allowed.
- Approach casual, part-time and full-time rosters differently: casuals are flexible but still protected; part-time agreed hours need written variation; full-time changes must respect breaks and spans of hours.
- Use a simple process: review the rules, consult in writing, decide, confirm and post the roster, then keep records.
- Watch the flow-on effects: roster changes often impact breaks, overtime, penalty rates and allowances – pay correctly.
- Strong basics (tailored Employment Contracts, a Staff Handbook policy and consistent records) make compliance smoother and reduce disputes.
