Employment Leave Act: Why your biggest transition risk may sit outside payroll

For most employers, the Employment Leave Act comes into force on 6 August 2028. Many employers will initially treat the change as a payroll-system project: wait for the software provider to update the calculations, test the release and prepare for go-live.

That view is understandable. It is also likely to leave important risks unresolved.

The new legislation changes more than the way leave is calculated. It increases the importance of information that sits across employment agreements, rostering, timekeeping, workforce management and payroll. A system can only calculate correctly when the organisation has first defined the right inputs and can supply them consistently.

In other words, one of your biggest payroll risks may be something payroll cannot fix on pay day.

Why this is not simply a software update

Under the current Holidays Act, experienced payroll teams often make sense of imperfect arrangements at the end of the process. They interpret patterns of work, investigate exceptions, reconstruct missing information and find a defensible way to pay an employee correctly.

Under the Employment Leave Act, several key inputs will need to be understood much earlier and maintained more deliberately. Employers will need reliable information about agreed work patterns and standard, additional and casual hours, together with accurate day-by-day records where these are required to apply the new rules.

Your payroll provider should be expected to build and test the new calculations. It cannot, however, decide what your employment agreements mean, define a week for your employees, repair unclear rostering practices or create data that the organisation has never captured.

That is why the transition needs to involve Payroll, HR, Finance, operational managers, employment advisers and system providers. If it is left solely with payroll, some of the most important decisions may never reach the people authorised to make them.

The deceptively difficult question: what is a week?

In practical terms, employers need to be able to answer a deceptively simple question: what does a normal working week look like for this employee?

Organisations will need to be much clearer about the hours and working patterns that make up each employee’s agreed working arrangements.

For someone who consistently works the same five days and the same hours, the answer may appear obvious. For employees with rotating rosters, changing shifts, seasonal work, multiple roles, additional hours or genuinely variable patterns, it can be much more difficult.

The issue is not merely mathematical. An organisation may need to establish what has been agreed with the employee, whether the written agreement reflects reality, and how subsequent changes will be recorded. Payroll cannot safely invent that answer when a leave request arrives.

Employers should therefore begin testing several questions now:

• Are work patterns clearly described in employment agreements?
• Do the agreements match how people actually work?
• How are changes to standard hours agreed and recorded?
• Can standard hours be distinguished from additional hours?
• Who is responsible for notifying payroll when an agreed pattern changes?
• Can the organisation produce accurate day-by-day hours when required?

If different teams give different answers, that is already useful information. It identifies a governance and process gap that should be resolved before new calculations are introduced.

Existing employment agreements may preserve old obligations

Another transition risk sits in the wording of individual and collective employment agreements.

Some agreements simply provide the minimum entitlement required by the legislation in force at the time. Others state specific leave entitlements or calculation methods. Existing employment agreements will need to be reviewed carefully. Some contractual provisions may require alignment with the new statutory framework, while more generous contractual benefits may continue to have effect. The treatment of individual and collective agreement provisions should be assessed with appropriate legal advice.

The Act also provides a transitional process for aligning existing employment agreements with the new framework. Organisations should understand how that process applies to their agreements and seek appropriate legal advice where contractual terms may need to change.

The Employment Leave Act may produce broadly comparable entitlements overall, but the outcome will not be identical for every employee. Organisations should not assume that every existing clause will automatically align with the new framework.

‍

This creates several practical questions:

• Which agreements refer to the legislation, and which prescribe their own entitlement?
• Are there different clauses across business units, employee groups or collective agreements?
• Could legacy wording require an organisation to maintain a more generous outcome?
• Will changes require consultation, agreement or collective bargaining?
• Could payroll need to support different methods during a transition period?

This review should involve appropriate employment-law advice. PPS can support the payroll interpretation, data analysis, modelling and operational design, but contractual changes need to be managed through the correct legal and employment-relations processes.

High leave balances create a financial and behavioural question

Employers with significant outstanding leave balances should also model what happens across the transition.

The issue is not simply the value shown in the general ledger. Employees may respond differently once they understand that the calculation method is changing. Some may choose to take leave before the new rules begin. Depending on the transitional treatment, contractual arrangements and system design, some organisations may need to distinguish between existing balances and entitlements accrued under the new framework.

A useful review should therefore consider:

• the size and distribution of current leave balances;
• which employee groups present the greatest exposure;
• how existing entitlements will be treated at transition;
• whether different scenarios materially change the financial outcome;
• whether additional system fields or separate calculation logic may be required; and
• how leave-management decisions could affect operational capacity before go-live.

Early cost modelling gives management time to make deliberate decisions. Discovering the impact during implementation turns the same issue into a deadline-driven problem.

Data readiness may be the real implementation constraint

Organisations often focus on whether their payroll platform will be ready. A better question is whether the data reaching that platform will be complete, accurate and timely.

The new framework increases the need for clear connections between HR, rostering, timekeeping and payroll. If an employee changes their agreed pattern but the information remains with their manager, the payroll calculation may still be wrong even if the software is working exactly as designed.

This makes data ownership critical. As a matter of good payroll governance, PPS recommends that every important input should have:

• a clear source;
• an accountable owner;
• an agreed approval process;
• a reliable route into payroll;
• an effective date; and
• an audit trail.

Flexible workforces will require particular attention. Hospitality, healthcare, education, retail and other roster-driven environments may have valid reasons for variable work patterns, but flexibility does not remove the need to define, capture and communicate the relevant information.

Capability cannot be installed with the system release

Payroll requires an unusual combination of employment legislation, mathematics, systems knowledge, finance, logic and operational judgement. It is difficult to find all of that capability in one person, and the Employment Leave Act will create questions that cross several professional boundaries.

Generic training has value, but organisations also need to understand how the Act interacts with their own agreements, workforce and systems. A standard example rarely reflects the employee who works in two roles, the team with a rotating roster, the collective agreement with legacy wording or the manager who changes a shift without updating the source system.

Effective preparation should therefore include scenario-based learning using the organisation's real arrangements. This helps teams identify where the legislation is understood, where internal practices are inconsistent and where further advice or design work is needed.

PPS provides tailored in-house training ranging from focused sessions of a few hours to detailed one- or two-day programmes. These sessions can use your actual workforce scenarios, explore existing system and process issues, and give Payroll, HR, Finance and managers a shared understanding of their responsibilities.

What employers should do now

There is no need to panic, but there is a strong case for starting early. The purpose of an initial review is not to redesign everything immediately. It is to identify which parts of the transition will require time, agreement, investment or specialist advice.

At a minimum, organisations should:

1. Establish cross-functional ownership for the transition.
2. Map the employment agreements and workforce arrangements in scope.
3. Identify employee groups with variable or complex work patterns.
4. Assess whether standard hours, additional hours and daily time data are available and reliable.
5. Review how changes to agreed work patterns reach payroll.
6. Model the treatment and potential cost of existing leave entitlements and high balances.
7. Engage payroll, rostering and timekeeping vendors about required data and implementation plans.
8. Identify the training needs of Payroll, HR, Finance and operational managers.
9. Build sufficient time for employment-agreement review, consultation and, where applicable, bargaining.
10. Complete a formal readiness review well before the final implementation year.

Start with clarity, not configuration

The Employment Leave Act may simplify some calculations, but it does not remove complexity. In many cases, it moves that complexity into the definition of work patterns, the quality of employment agreements, the flow of operational data and the decisions made before payroll begins processing.

The organisations that handle the transition well will not necessarily be those that configure their systems first. They will be those that first understand their workforce, contractual obligations, data and exposure.

PPS has already begun cost modelling and transition planning with clients. We can support your organisation through:

• Employment Leave Act readiness reviews;
