Unfair Dismissal & Internal Messaging Apps

On 25 June 2026, the Fair Work Commission (FWC) ruled that Amazon Commercial Services Pty Ltd (Amazon) unfairly dismissed an employee for unprofessional messages sent via the company’s internal messaging platform, Slack, and other alleged misconduct. The decision highlights the importance of context, proportionality, and procedural fairness in disciplinary actions and dismissal.

Background

The employee, a Technician at Amazon’s Fulfilment Centre, was dismissed for several reasons, including inappropriate comments on Slack directed at a Senior Technician, alleged performance issues, and sending confidential information to his personal email. Slack, which is used by Amazon employees for both formal and informal communication, was described as a platform where casual and irreverent exchanges, including jokes and swearing, were common.

The FWC’s findings on the Dismissal

The FWC found that Amazon lacked a valid reason for the dismissal, citing the following key points:

1. Slack Messages

While the employee’s comments on Slack were deemed unprofessional and made the Senior Technician feel disrespected, they were contextualised within the workplace culture. Slack was frequently used for casual and offhand communication, and the comments were considered to be at the lower end of seriousness, not amounting to harassment or discrimination.

2. Performance Issues

Allegations regarding the employee’s work performance were not found to involve dishonesty and did not justify dismissal.

3. Policy Breach

The employee’s unauthorised act of sending confidential information to his personal email occurred during a disciplinary investigation and was intended to respond to allegations. While this was a breach of policy, it was minor, caused no harm to Amazon, and did not constitute a valid reason for dismissal.

4. Procedural Deficiencies

The FWC noted procedural flaws in Amazon’s investigation and decision-making process, as well as the company’s failure to address escalating tensions between the employee and the Senior Technician.

Outcome of the Dismissal

The FWC ordered the employee’s reinstatement, rejecting Amazon’s argument that trust and confidence had irreparably broken down. The FWC found that the relationship between the employee and the Senior Technician could be restored. Orders were also made to ensure continuity of employment, and the parties were directed to address lost remuneration.

Key Takeaways for Employers

This case underscores several critical lessons for employers, including:

1. Context Matters

When assessing employee conduct, it is essential to consider the broader workplace culture and norms. In this case, the casual use of Slack influenced the FWC’s determination that the comments, while unprofessional, did not warrant dismissal.

2. Proportionality in Disciplinary Actions

Not all breaches of policy or instances of misconduct justify dismissal. Employers should assess the severity of the conduct and consider alternative measures, such as targeted training or counselling, where appropriate.

3. Procedural Fairness

A fair and thorough investigation process is crucial. Procedural deficiencies, such as failing to address workplace tensions or to retrieve confidential information, can undermine the validity of a dismissal.

4. Restorative Potential

Employers should carefully evaluate whether workplace relationships can be repaired before asserting that trust and confidence have irretrievably broken down.

Practical Steps for Employers

To avoid similar outcomes, employers should:

  • Clearly communicate workplace policies and ensure employees understand acceptable standards of behaviour, particularly when using internal communication tools.
  • Regularly review and update workplace policies to reflect the realities of workplace culture and technology use.
  • Conduct thorough and impartial investigations into alleged misconduct, ensuring procedural fairness at every stage.
  • Consider proportional responses to misconduct, including training or counselling, before resorting to dismissal.
  • Address workplace tensions proactively to prevent escalation.
  • By taking these steps, employers can better manage workplace issues and reduce the risk of adverse findings in unfair dismissal claims.
