Double Duty: Can Employees Work Full-Time and Casual for the Same Employer?
Every year around Christmas, I get the same question from business owners:
“Can my employee work full-time during the week and pick up casual shifts for me on weekends?”
It sounds simple, but it’s one of the trickiest compliance issues small businesses face.
The short answer?
✅
Yes, it’s possible.
🚩
But only if it’s done correctly.
Why It's A Problem for Some Businesses?
The line between “helping out with a few extra shifts” and “breaching the Award” can be thin.
Without the right structure, you risk:
- Underpaying overtime or weekend penalties
- Breaching Award or NES obligations
- Creating confusion about hours, roles, or entitlements
- Accidentally doubling up on leave accruals or tax
The key is making sure each role is
clearly defined, voluntary, and legally distinct.
The 3 Must-Haves for Dual Employment
If a team member works both full-time and casual for you, make sure these boxes are ticked:
1. The employee must request the arrangement.
It has to be their choice - not yours. If the idea comes from the business, it could look like pressure to take on extra work or avoid overtime costs.
2. The duties must be distinctly different.
The two roles can’t just be the same job with a different label. For example:
👎 A full-time warehouse worker who picks up weekend “casual shifts” doing the same job.
👍 A full-time admin assistant who also works occasional weekend events for the company.
3. Each role needs its own contract.
You’ll need two separate employment contracts - one for the permanent role, one for the casual. Each should list:
- The correct Award and classification
- Distinct duties and responsibilities
- Relevant pay rates and conditions
- This helps prove the roles are genuinely separate if Fair Work ever asks.
Common Mistakes To Avoid
These are the issues I see most often when reviewing business setups:
- Using casual shifts to “avoid overtime” (a huge red flag).
- Only having one contract covering both roles.
- Not documenting which hours relate to which job.
- Paying flat rates that don’t meet Award requirements.
If any of those sound familiar, it’s time for a quick check before Fair Work does it for you.
Quick Compliance Checklist
Here’s a simple way to check if your setup stacks up:
☑️ The second job was requested by the employee.
☑️ The roles have different duties.
☑️ You have two contracts, each referencing the right Award.
☑️ You’re paying correct rates and penalties for both.
If you can tick all four — you’re in good shape. If not, it’s worth a closer look.
The Takeaway
Yes, an employee can work full-time and casual for the same employer - but the moment it’s done for convenience or cost-saving, you risk crossing into non-compliance territory.
The fix is simple: keep roles separate, contracts clear, and decisions voluntary.
