Unfair dismissal claims often turn on what an employer knew at the time of termination. However, information discovered after dismissal can still play a decisive role.
Our firm successfully acted in an unfair dismissal matter involving a senior salesman in the heavy engineering sector. The case highlights important lessons for both parties on how post-termination information may support or undermine a dismissal decision.
Case Background
The employee worked as a high-performing salesman for more than six years. The employer alleged misconduct and claimed the employee had engaged in unauthorised business activities that breached the company’s code of conduct.
The employer conducted an investigation and put the allegations to the employee. The employee denied the claims and cooperated with the process. Despite these assertations of innocence and his compliance with the company’s investigation, the employer terminated his employment.
After the dismissal, the employee returned his company laptop. The employer then conducted an IT review of the device. That review uncovered records which appeared to contradict the employee’s earlier statements.
The employer relied on this material to argue that the dismissal was justified and reasonable, despite discovering the information after termination.
The Legal Context: Post-Termination Evidence
This case closely reflects principles applied by the Fair Work Commission in Finemore v CMIB Insurance Services Pty Limited [2016] FWC 8517¹.
In Finemore, the Commission upheld a dismissal after the employer discovered misuse of confidential information following termination. The Commission accepted that post-termination evidence can support a dismissal, provided it proves that the employer had a valid reason at the time.
The key takeaway is clear, post-termination evidence can matter, but it does not excuse a flawed dismissal process.
Key Lessons for Employees and Employers on Post-Termination Evidence
Recent unfair dismissal cases show that information discovered after employment ends can still affect the outcome of a dispute. Both employees and employers should understand how post-termination evidence, procedural fairness, and timing interact under employment law.
1. Evidence Handling and Timing
For Employers
Post-termination evidence can support a dismissal decision. This may include data found on returned company laptops, phones, or IT systems.
Employers must obtain and use this evidence lawfully. This requires compliance with privacy laws, workplace policies, and procedural fairness obligations. Evidence gathered improperly can weaken a defence to an unfair dismissal claim.
For Employees
Employees should understand that actions taken during employment may still come under review after termination. Records stored on company systems do not disappear when employment ends.
Employees should comply with workplace policies and act honestly throughout employment. Post-termination discovery of misconduct can affect the outcome of an unfair dismissal application.
2. Procedural Fairness Remains Critical
For Employers
Procedural fairness plays a central role in unfair dismissal cases. Employers must give employees a genuine opportunity to respond to allegations before making a termination decision.
If new information emerges after dismissal, employers should assess whether it confirms the original reasons or exposes procedural weaknesses. Post-termination evidence does not cure an unfair process.
For Employees
Employees should provide complete and accurate responses during disciplinary investigations. Inconsistent explanations can damage credibility.
If new evidence arises later, employees should address it directly to reduce legal risk.
3. Documentation and Record Keeping
For Employers
Clear records strengthen a defence to unfair dismissal claims. Employers should document investigations, meetings, employee responses, and decision-making reasons.
Well-kept records help demonstrate that the employer considered all relevant factors and followed a fair process.
For Employees
Employees should also retain records of communications and key events. Written evidence that aligns with workplace policies can support a claim if a dispute arises.
4. Legal Advice and Representation
For Both Parties
Unfair dismissal disputes often turn on technical legal issues. Early legal advice helps both parties understand their rights, obligations, and risks.
Employment lawyers can assess post-termination evidence, procedural fairness, and strategy before disputes escalate.
Conclusion: Handle Post-Termination Evidence With Care
Post-termination information can influence unfair dismissal outcomes. Employers must investigate lawfully and fairly. Employees must act honestly and comply with workplace policies throughout their employment.
Early involvement of an experienced employment lawyer can protect rights, reduce risk, and improve outcomes for both parties.
