Unfair dismissal Australia 2026: Avoid expensive tribunal claims
What Is Unfair Dismissal (And Why It’s Expensive)
You fire an employee. They claim you were unfair. They file a claim at the Fair Work Commission.
If the tribunal agrees with them, you must:
- Reinstate them (bring them back to work)
- Pay lost wages (sometimes 12+ months)
- Pay compensation (up to 6 months wages)
- Pay legal costs (sometimes $10K+)
Total cost: $50,000–$200,000+ per claim.
And it’s public. Your business name appears in tribunal decisions.
When Dismissal Is Unfair
Fair Work looks at three questions:
1. Was there a valid reason?
Valid reasons:
- Serious misconduct (theft, violence, gross negligence)
- Repeated poor performance (documented)
- Redundancy (genuine business need)
- Incapacity (can’t do the job)
Invalid reasons:
- “I don’t like them”
- Personal dispute
- Took parental leave
- Reported safety issue
- Complained about wages
- Union membership
- Disability
2. Was the process fair?
Fair process means:
- Warning (written notice of issue)
- Opportunity to respond (hearing their side)
- Documentation (records of conversations)
- Consideration (reviewing their response)
- Notice or payment (usually 2 weeks)
Unfair process:
- Fired on the spot (no warning)
- No chance to explain
- No documentation
- Instant dismissal
3. Was dismissal proportionate?
Proportionate means:
- Serious misconduct = instant dismissal OK
- First-time minor error = warning first
Disproportionate:
- First absence = fired immediately
- Small mistake = terminated
Common Mistakes Businesses Make
Mistake 1: Firing on the spot
Employee makes a mistake. You’re angry. You say, “You’re fired.”
Reality: Unless it’s serious misconduct, this is unfair. They can claim $50K+ compensation.
How to avoid: Give warning. Document the issue. Schedule a meeting. Let them respond.
Mistake 2: No written documentation
You’ve complained verbally 5 times. Employee says it never happened. No written record.
Reality: Tribunal believes the employee. No proof you gave warnings.
How to avoid: Email after each conversation. “Following our chat today about X, we need you to improve by Y date.”
Mistake 3: Firing after they take leave
Employee takes parental leave. Returns. You fire them 2 weeks later.
Reality: Illegal. Automatically unfair. Tribunal will order reinstatement + compensation.
How to avoid: Don’t fire employees who recently returned from protected leave. Wait 3+ months if possible.
Mistake 4: Redundancy without genuine need
You say, “We’re downsizing.” Employee loses job. You hire a replacement 3 months later doing the same work.
Reality: Unfair. The redundancy wasn’t genuine. Tribunal orders reinstatement.
How to avoid: Ensure redundancy is real. Don’t replace the role. Document the business reason.
Mistake 5: Dismissing for raising safety concerns
Employee reports a hazard. You don’t like the complaint. You fire them.
Reality: Automatically unfair. Protected by law. Tribunal orders reinstatement + maximum compensation.
How to avoid: Never dismiss for reporting safety issues. It’s illegal.
The Correct Dismissal Process
Step 1: Identify the problem (1 week)
- Document specific issue
- Performance, conduct, or redundancy
- Get HR/legal advice
Step 2: First warning (written)
- Email outlining the issue
- What needs to change
- By what date
- Consequences if not fixed
- Keep a copy
Step 3: Monitor improvement (2–4 weeks)
- Check if they’re improving
- Document progress (or lack thereof)
- Keep records
Step 4: Final warning (if needed)
- If no improvement, issue final warning
- Written notice
- Clear: this is final warning
- Last chance to improve
Step 5: Dismissal meeting
- Schedule meeting
- Allow them to bring support person
- Explain decision
- Offer appeal process
- Provide written notice
Step 6: Notice or payment
- Give 2+ weeks’ notice
- Or pay in lieu (full 2 weeks salary)
- Final pay includes all accrued leave
- Provide written reference if requested
Redundancy (Special Rules)
If you’re genuinely downsizing:
- Consult employees (explain why)
- Consider alternatives (retraining, redeployment)
- Select fairly (not based on age, disability, etc.)
- Offer severance (usually 1+ weeks per year employed)
- Provide notice or payment in lieu
Failure to follow these steps = unfair dismissal claim.
