Casual vs Part-Time vs Full-Time: Getting the Classification Right to Avoid Fair Work Penalties

Estimated read time: 7 minutes · Last updated April 2026

Calling a worker “casual” when they are actually a regular part-time employee is one of the most common and most expensive mistakes in Australian small business payroll. Since 27 February 2024, civil penalties for misclassification and underpayment sit at up to $495,000 per contravention for an individual — and intentional underpayment became a criminal offence on 1 January 2025.

Employment type is not a label you pick. It is a legal category with a specific definition, and the consequences of getting it wrong flow through every entitlement: leave, notice, casual loading, redundancy, and superannuation.

This post lays out the three core types, how the Fair Work Act defines them today, and the specific traps small businesses fall into.

The three types under the National Employment Standards

The FWO types-of-employees page is the primary reference. At a high level:

• Full-time: ongoing employment, around 38 ordinary hours a week, paid leave entitlements.
• Part-time: ongoing employment, agreed regular hours under 38 a week, paid leave entitlements on a pro-rata basis.
• Casual: no firm advance commitment to ongoing work, paid a casual loading in place of paid leave.

The single hardest line to hold is the casual one. It is defined not by what you call the worker, but by the nature of the arrangement.

What makes an employee actually casual

The FWO casual employees page is the authoritative source. In plain English, an employee is casual when there is no firm advance commitment from the employer to continuing and indefinite work with an agreed pattern. The test looks at the real substance of the relationship, not the wording of the contract.

Indicators that a worker is actually casual:

• Shifts offered and accepted on a per-shift basis.
• No guaranteed hours week to week.
• The worker can reasonably refuse a shift.
• The worker receives a casual loading on their pay slip.

Indicators that the “casual” label may not hold up:

• The same roster every week for months.
• Agreed ongoing hours that the worker is expected to show up for.
• Paid leave arrangements that look permanent.
• Disciplinary consequences if the worker declines a shift.

If you recognise your business in the second list, the question isn’t whether the worker is really casual — it is what to do about it.

Entitlements, compared

This is where the cost of misclassification compounds.

• Paid leave. Full-time and part-time employees accrue annual leave and personal/carer’s leave. Casuals don’t — that is what the casual loading is for.
• Notice and redundancy. Full-time and part-time employees are entitled to notice of termination under the National Employment Standards. Casuals generally are not.
• Casual loading. Paid on top of the ordinary hourly rate, set by the applicable Modern Award. See your award’s summary page — for example, the Hospitality Award summary or the General Retail Award summary.
• Super. All three types accrue super on ordinary time earnings at the current rate set out on the ATO’s key super rates and thresholds page.

The casual conversion pathway

If a casual has been working regular, systematic hours over a qualifying period, they have a right to become a permanent employee. The detail sits on the FWO casual employees page under casual conversion.

The key points for owners:

• The obligation to offer or consider conversion is on you, not on the employee.
• You must provide written notice confirming whether or not the conversion is offered, and why.
• Ignoring the obligation doesn’t make it go away. It creates an additional contravention.

Practically, if you have a “casual” who has worked a consistent roster for six months, do the conversion assessment now. Either offer permanent employment or document in writing the operational reasons why it is not reasonable.

The cost of getting it wrong

Misclassification shows up in two directions.

Calling a permanent employee “casual”. The FWO can recover unpaid annual leave, personal leave and notice periods going back through the whole employment history, plus civil penalties under the Fair Work Act litigation framework. Where it looks deliberate, the case can be referred for criminal prosecution under the laws that commenced 1 January 2025.

Calling a true employee a “contractor”. This is sham contracting and is treated separately under the Fair Work Act. Penalties apply per contravention at the same civil penalty scale — up to $495,000 for an individual, more for serious contraventions. The Closing Loopholes reforms tightened the rules around sham contracting and added a reasonableness defence, but that defence has to be documented, not assumed.

A simple small-business test

For each person you pay, ask three questions:

• Does the worker have a firm, agreed pattern of hours I am committed to each week?
• Am I the only business they work for, using my tools, under my direction?
• Would I be surprised if they didn’t turn up to their usual shift?

If the answer to any of these is yes, they are probably not a casual, and they are probably not an independent contractor either. That is the point at which the conversation shifts from “what am I calling them” to “what am I paying them.”

What to do this week

• List every worker and write their current type next to their name.
• For anyone marked “casual”, check the last 12 weeks of rosters. If the pattern is consistent, flag for conversion review.
• For anyone marked “contractor”, check who owns the tools, who sets the hours and whether the worker invoices other clients. If in doubt, move them to employee.
• Document the reasoning for each classification in a one-line file note.

The bottom line

The label on the pay slip isn’t what decides it. The substance of the working arrangement decides it, and the FWO reads that substance against the Fair Work Act — not against your contract. Getting classification right is cheaper than defending the wrong answer.
