What is a Unfair dismissal?

Updated 20 Jan 2026 5 min read

Unfair dismissal occurs when an employee is dismissed in a manner that is harsh, unjust, or unreasonable. Under the Fair Work Act, eligible employees can apply to the Fair Work Commission for an unfair dismissal remedy within 21 days of their dismissal taking effect. Remedies include reinstatement or compensation up to 26 weeks' pay.

Understanding unfair dismissal

Unfair dismissal protections under the Fair Work Act balance employer needs to manage their workforce with employee rights to fair treatment when their employment ends.

What makes dismissal unfair

  • No valid reason
  • Harsh, unjust, or unreasonable
  • Lack of procedural fairness
  • No opportunity to respond

Key timeframes

  • 21 days to lodge claim
  • 6 months minimum service
  • 12 months for small business
  • Max 26 weeks compensation

Eligibility for unfair dismissal

Not all employees can claim unfair dismissal. To be eligible, an employee must:

Eligibility requirements

Service: Completed minimum employment period
Coverage: Covered by NES system
Dismissed: Actually been dismissed
Income cap: Below high income threshold ($175,000 in 2024) OR covered by award/agreement

What the FWC considers

When assessing whether a dismissal was unfair, the Fair Work Commission considers multiple factors:

  • Valid reason: Was there a genuine reason related to capacity or conduct?
  • Notification: Was the employee told the reason for dismissal?
  • Opportunity to respond: Did the employee have a chance to address concerns?
  • Support person: Was the employee allowed to have a support person?
  • Warnings: For performance issues, were warnings given?
  • Business size: Impact of employer's size on procedures
  • HR resources: Availability of HR expertise
  • Any other relevant matters

21-day deadline is strict

Unfair dismissal applications must be lodged within 21 days of dismissal. The FWC rarely grants extensions. For employers, this means any claim will be lodged quickly—ensure your documentation supports the dismissal decision from the outset.

Defending an unfair dismissal claim

Good defences

  • Valid reason documented
  • Fair process followed
  • Warnings given for performance
  • Opportunity to respond given

Automatic exclusions

  • Genuine redundancy
  • Under minimum employment period
  • Casual without regular pattern
  • Fixed-term contract ending

Common mistakes leading to unfair dismissal findings

No opportunity to respond

Dismissing an employee without giving them a chance to respond to the allegations or concerns. This is a key procedural failure.

No warnings for performance

Dismissing for poor performance without prior warnings or a performance improvement process.

Disproportionate response

Dismissal is too harsh for the conduct—for example, instant dismissal for a minor first offence that doesn't constitute serious misconduct.

Key takeaways

Unfair dismissal protections require employers to have valid reasons and follow fair processes when ending employment. Documentation is essential—records of performance issues, warnings, and the opportunity given to respond can determine the outcome of a claim.
