How To Calculate Continuous Service For Redundancy Pay

Redundancy is one of those words no small business owner wants to deal with - but at some point, many growing (and even stable) businesses face a restructure, downturn, loss of a key contract, or shift in strategy that makes certain roles no longer required.

When that happens, one of the biggest legal and commercial risks is getting the employee’s continuous service wrong. Continuous service affects redundancy pay, notice periods, and in some cases whether you can claim exemptions (or whether an employee can challenge the process).

This guide breaks down what continuous service means for redundancy in practice for Australian small businesses, how continuous service is calculated, and what to watch out for when you’re making redundancy decisions.

What Does “Continuous Service” Mean For Redundancy?

When people search for continuous service and redundancy, they’re usually trying to answer a very practical question:

“How long has this employee really been employed for, and how does that affect what I need to pay them (or consult about) if their role is redundant?”

In most cases, continuous service means the period the employee has been employed by you (their employer) without their employment being ended and restarted.

Continuous service matters because it is often used to calculate:

• Redundancy pay (how many weeks you owe, if redundancy pay applies)
• Notice of termination (or payment in lieu of notice, if you end employment immediately)
• Other entitlements depending on an award, enterprise agreement, or contract (for example, some awards have consultation requirements, redeployment steps, or extra rules around terminations)

It’s important to separate two things that often get mixed up:

• Service for redundancy/notice under the Fair Work Act 2009 (Cth) and the National Employment Standards (NES), and
• Service for leave entitlements (like annual leave and personal/carer’s leave), which can have slightly different rules depending on what happens during employment.

If you’re planning a redundancy, it’s worth checking the employee’s start date, the exact employer entity, and any changes to their employment status before you assume the service period is straightforward.

Why Continuous Service Matters In A Redundancy (And Where Small Businesses Get Caught)

From a small business perspective, continuous service can impact your redundancy decision in two big ways:

• Cost (the longer the service, the higher the redundancy pay and notice obligations can be)
• Risk (miscalculations can lead to underpayment claims, disputes, or a process that looks unfair)

Where businesses commonly get caught is when employment history is not “clean”. For example:

• The employee started as a casual and later became permanent.
• The employee worked for a related business, then moved across to your entity.
• The business was sold and you took on staff as part of the transition.
• There was a gap in work (such as a stand down, seasonal break, unpaid leave, or workers’ comp absence) and it’s unclear if service was broken.
• The employee resigned, then came back later, and you’re unsure whether this counts as one continuous period or two separate periods.

These details matter because redundancy pay under the NES is tied to years of service, and if you get the service period wrong, you can easily get the redundancy pay wrong.

It’s also worth remembering: redundancy is not just about payment. A redundancy should be a genuine redundancy, which usually involves consultation (where required), considering redeployment, and ensuring the role is no longer required due to operational changes - not because of an employee’s performance.

How Continuous Service Is Calculated For Redundancy Pay

To handle continuous service properly in a redundancy, you need a repeatable process for calculating service.

Step 1: Identify The Legal Employer

The first question is: who is the employer?

In many small businesses, the trading name is not the same as the legal entity. If an employee has been employed by different entities over time (even if the brand and workplace looked the same), their continuous service may not automatically carry across.

This is especially important if you operate with multiple entities, such as different companies or trusts.

Step 2: Confirm The Start Date (And Any Breaks In Employment)

Usually, continuous service starts on the employee’s employment start date and runs until the termination date.

A true “break” generally occurs if employment is terminated and later a new employment relationship begins. However, not every absence breaks continuous service.

Examples of periods that commonly occur during continuous service include:

• annual leave
• personal/carer’s leave
• parental leave (paid or unpaid)
• unpaid leave that is approved
• community service leave (like jury duty)

These are typically not “breaks” in continuous service in the way employers worry about. But they can still affect calculations in certain contexts (for example, some unpaid leave periods may not count as service for some entitlements).

Step 3: Check Status Changes (Casual To Permanent)

A very common issue is where a worker starts as a casual and later becomes full-time or part-time.

As a practical rule of thumb under the NES, casual employees aren’t entitled to redundancy pay. If a casual later becomes a permanent employee, redundancy pay is usually calculated from when their permanent employment started (not their earlier casual engagements) unless an award, enterprise agreement, or contract provides a more generous outcome.

As a practical step, you should:

• check whether there was a clear conversion point (with paperwork), and
• confirm what the applicable award, agreement, or contract says (if anything) about recognising earlier service.

If your contracts and records are unclear, this is where payroll data, rosters, and written communications become important.

Having clear onboarding documentation and the right Employment Contract from the start can save a lot of uncertainty later.

Step 4: Consider Business Sales And Transfers

If you bought a business and retained employees, continuous service can become complex quickly.

Depending on whether there’s a “transfer of business” under workplace laws and whether the new employer recognises prior service, an employee’s service may carry over for some purposes. In other situations, service may not be recognised by the new employer - but that doesn’t automatically mean liabilities disappear, and there can still be redundancy, consultation, and other compliance issues to manage carefully.

If you’re acquiring a business, it’s also smart to do legal due diligence early so you know what employment liabilities you’re inheriting. This is particularly relevant where the outgoing owner has underpaid wages or misclassified employees.

Does A Small Business Have To Pay Redundancy If Continuous Service Is Long?

Many business owners assume longer continuous service automatically means a redundancy payout is unavoidable.

In reality, redundancy pay depends on multiple factors - and one of them is whether you’re a small business employer under the Fair Work Act (generally, fewer than 15 employees).

If you are a small business employer (as defined), you may be exempt from paying redundancy pay under the NES. However:

• you can still have obligations under an award, contract, or enterprise agreement (depending on what applies),
• you still need to comply with notice requirements, and
• you still need to manage the process carefully to reduce the risk of claims.

Even if you don’t owe redundancy pay, you should not treat redundancy as a “quick exit”. A poorly handled termination can create legal and cultural fallout, including disputes, reputational harm, and loss of trust with remaining staff.

Also, if you’re close to the 15-employee threshold, it’s worth double-checking how you count employees. For example, headcount can be affected by associated entities, and some casual employees may be counted if they are employed on a regular and systematic basis.

Practical Steps To Manage Redundancy And Continuous Service Correctly

If you want to manage redundancy and continuous service in a way that’s both legally compliant and practical, you need a process you can follow each time.

1) Document The Operational Reason For The Redundancy

Start with the business reason and put it in writing. Examples include:

• loss of a major client contract
• automation or new software reducing workload
• closing a location or reducing trading hours
• restructure due to financial pressure

This matters because redundancy should be about the role being no longer required, not about performance or conduct.

If the driver is performance, you generally need a different approach (such as performance management) rather than a redundancy label.

2) Confirm The Employee’s Continuous Service Timeline

Create a simple “service timeline” for the employee, including:

• start date and employment status at start
• any changes (casual to part-time/full-time, promotions, secondments)
• any periods of unpaid leave or extended absence
• the legal employer entity at each stage

This is where you reduce the chance of underpaying or overpaying entitlements.

3) Check The Applicable Industrial Instrument

Even when the NES provides the baseline, an award or enterprise agreement can add steps, including consultation obligations.

This is one of the most common “hidden risks” in redundancy: the pay might be right, but the process is wrong.

Also, if you rely heavily on rosters and shift changes, it’s a good idea to have clear rules in place so you’re not creating inconsistent practices that come back to bite you later. A well-drafted set of workplace arrangements (and supporting policies) can help you manage that consistently over time.

4) Get The Notice Period Right (Or Pay In Lieu)

Notice can be a major source of disputes, especially when redundancies happen quickly.

If you’re paying out notice rather than having the employee work the notice period, you’ll want to handle payment in lieu of notice properly - including ensuring the final pay slip reflects the correct breakdown and checking superannuation treatment, which can depend on what the payment is for and how it’s characterised.

Also check whether the employee is taking leave during their notice period, as this can affect timing and payout calculations.

5) Calculate Final Pay Items Beyond Redundancy

Redundancy pay (where it applies) is only one part of the “final pay” picture.

Your final pay calculation may also need to include:

• unused annual leave
• any leave loading (if applicable under an award or contract)
• outstanding wages up to the termination date
• overtime or penalty rates that have been worked but not yet paid
• reimbursements owed

If you’re uncertain, it’s often worth doing a parallel “sense check” calculation before issuing the final pay, particularly for long-serving employees or where rostering is complex.

6) Make Sure Your Paperwork Supports The Decision

Good paperwork is not about being bureaucratic - it’s about reducing ambiguity.

At minimum, you want:

• a termination letter that clearly explains redundancy and key dates
• records of consultation (if required)
• a breakdown of how you calculated continuous service and final pay
• up-to-date employment contracts and policies

If your existing documents are inconsistent (for example, you’ve grown quickly and hired people informally), it may be time to review and standardise your suite of documents, including your Workplace Policy settings for things like leave requests, notice expectations, and changes to working arrangements.

Common Continuous Service Redundancy Scenarios (And How To Think About Them)

Every business is different, but there are patterns we see regularly when advising small businesses.

Scenario A: The Employee Took Extended Unpaid Leave

Extended unpaid leave is a common “grey area” for employers because it feels like a break in work.

As a general principle, approved leave is usually not a termination of employment - so the employment relationship continues.

The practical step is to:

• check any written approvals and correspondence, and
• confirm whether that leave period counts as “service” for the entitlement you are calculating (this can vary depending on the entitlement and applicable instrument).

Scenario B: The Employee Changed From Casual To Permanent

If the employee has a long history of casual work before converting, it can be tricky to determine what counts and from when.

This is where having clear conversion documentation (and a new or updated contract) is critical. If you’re converting casual staff, it’s worth doing it properly with documentation that matches the reality of the role.

Scenario C: You “Moved” Staff Between Related Entities

This is common in growing businesses: you start as a sole trader or under one company, then restructure or set up a new entity and move people across.

From the employee’s perspective, nothing changed. From a legal perspective, it might have.

If the employment contract does not clearly document the employer entity (or if the transfer isn’t documented properly), you can end up with disputes about continuous service and who owes what.

Scenario D: You’re Buying Or Selling A Business

Business sales are where continuous service and redundancy issues can become expensive quickly.

If you’re selling a business, you may want clarity in your sale documents about employee entitlements and whether employees are being transferred or terminated.

If you’re buying a business, you want to understand what employee liabilities you’re taking on - and the documentation should reflect this clearly. That’s why a structured process (like using an Business Sale Agreement suited to your transaction) is often essential.

Key Takeaways

• Continuous service issues in redundancy often come down to one key question: how long has the employee been employed by the legal employer, and has their employment ever been ended and restarted?
• Continuous service affects redundancy pay, notice, and sometimes the process you must follow (especially where an award or agreement requires consultation).
• Small businesses may be exempt from redundancy pay under the NES, but you can still have notice obligations and award/contract compliance requirements.
• Common “risk areas” include casual-to-permanent conversions, moves between related entities, business sales, and periods of unpaid leave or long absences.
• A practical redundancy process includes documenting the operational reason, building a service timeline, checking the applicable award/contract, and carefully calculating final pay.
• Up-to-date contracts and policies (including a clear Employment Contract and consistent Workplace Policy approach) reduce disputes and make service calculations far easier.
