Casual vs Permanent Staff at a Servo: The Honest Breakdown

Most petrol station operators did not sit down one day and design their staffing model. They hired their first person as a casual because it seemed easier, added a permanent employee when someone reliable wanted more hours, and ended up with a mix they never quite planned. That is fine for getting started. But if you are managing two or more sites, or trying to get your labour costs under control, it is worth actually thinking about which arrangement suits which role. Here is the honest breakdown.

What casual employment actually means at a servo

A casual employee has no guaranteed hours and no expectation of ongoing work. In exchange for that flexibility, they receive a loading on top of their base rate, currently 25% under the Vehicle Repair, Services and Retail Award (MA000089), which is the award that covers most petrol station workers in Australia.

Casuals must be engaged for a minimum of three consecutive hours per shift. They do not accrue annual leave or personal leave in the same way permanent employees do, though they are entitled to unpaid carer's leave and compassionate leave. After 12 months of regular and systematic engagement, casuals have the right to request conversion to permanent employment.

In practice, many servo operators have long-term casuals who work predictable hours week after week. That arrangement is legally fine but worth being deliberate about, because a long-term casual working regular hours costs more than a permanent employee doing the same work.

The real cost of casual loading

The 25% casual loading is the headline number, but it is not the full picture. The loading applies to the base rate before penalty rates are added. On a Saturday or a public holiday, that loading compounds on top of an already elevated penalty rate.

As a rough guide: a casual working a Saturday afternoon shift at a servo is costing you meaningfully more per hour than a permanent part-timer working the same shift. Over a year of regular Saturday shifts, that difference is significant. Most operators underestimate it because they are looking at base rates, not total cost.

The comparison most operators skip is the full cost of a permanent employee, including superannuation at 11.5%, leave entitlements, and notice periods. When you run the numbers honestly, a permanent employee working predictable hours is almost always cheaper per hour than a casual doing the same work consistently. The flexibility of casual employment has a real price, and it is worth knowing what you are actually paying for it.

Why permanent staff suit some roles and not others

Permanent employment makes the most sense for roles that are genuinely ongoing and predictable. Your morning opener who works Monday to Friday. Your experienced shift supervisor who handles the afternoon trade. Your most senior till operator who you would not want to lose.

These are people you have invested time in training. They know your POS system, your fuel ordering process, and how you like the forecourt run. That knowledge has value, and the best way to protect it is to give those people a permanent arrangement that makes them feel like they have a real job, not just shifts when you need them.

Casual employment makes more sense for roles that genuinely are irregular. Weekend cover. Holiday fill-ins. The student who can only work during semester breaks. Forcing a permanent arrangement onto genuinely variable hours creates compliance obligations you do not need.

The staffing mix most multi-site operators land on

Operators who have thought this through tend to end up with roughly the same structure: a core of permanent staff covering the predictable, high-value shifts, with a casual pool providing flexibility for the rest.

A reasonable starting point for a single busy servo: two to three permanent part-timers covering your reliable weekday shifts, and a pool of four to six casuals for weekends, evening cover, and last-minute gaps. The exact numbers depend on your trading hours and traffic patterns, but the principle holds.

For multi-site operators, the casual pool often serves multiple locations. A casual who is eligible and available to work at any of your sites gives you far more scheduling flexibility than casuals tied to a single location. Worth factoring in when you are hiring.

How your roster system should handle both types

Whatever mix you land on, your roster system needs to reflect it accurately. That means knowing, at the staff record level, whether someone is casual or permanent, what their contracted hours are, and what their availability looks like.

When you build a roster, you want to see at a glance which shifts are covered by permanent staff, which are casual, and where you are at risk of going over hours for either group. Casual oversharing is a real problem: casuals who work regular, predictable hours are building a legal case for conversion, and if you are not tracking it, you will not know it is happening until someone asks.

PIN clock-in is particularly important for casuals. Because their hours vary, accurate time records matter more, not less. An automated timesheet built from actual clock-in data is the cleanest way to make sure you are paying the right amount for the right hours, every single fortnight.
