One Email, 850 Addresses and a Dismissal

Rebecca Callow was a dump truck operator at the Carmichael Mine. She helped organise a work-shirt fundraiser for a colleague diagnosed with advanced cancer. The fundraiser had management authorisation, but the practical arrangements became the source of a serious dispute.

When Ms Callow sent an email about the fundraiser, the personal email addresses of approximately 850 employees and contractors were visible to recipients. She said she had intended to use blind copy and had made a mistake. Her employer dismissed her for serious misconduct, alleging breaches of privacy and confidentiality obligations.

The Commission looked at the whole situation

In Callow v M People (QLD) Pty Ltd [2025] FWC 2031, the Fair Work Commission examined the authorisation of the fundraiser, the guidance available to Ms Callow, her requests for assistance and the training she had received.

The Commission found that she did not use email as part of her ordinary duties and had not been trained in its use. It also considered evidence of previous occasions when management staff had disclosed personal information without evidence of disciplinary action.

The Commission was critical of the precision with which the reasons for dismissal were communicated and found Ms Callow had not been given an opportunity to respond to matters that informed the decision. It also considered the role of a manager who had not answered her enquiries and later made the final dismissal decision.

The outcome

The Commission found there was no valid reason for dismissal and that the dismissal was harsh, unjust and unreasonable. It ordered reinstatement with continuity of employment and service. It did not order payment for lost remuneration.

The case does not make an accidental disclosure harmless. Personal information deserves protection. It does show why a workplace investigation should consider what actually happened, the instructions and training available, and whether comparable conduct has been treated consistently.

If you are facing an investigation

Ask for the allegations and relevant policies in writing, where possible. Keep a record of the instructions you received, questions you asked and your response to the allegations. Consider asking for a support person and check any applicable workplace policy or agreement.

The result in another matter will depend on its own facts. If your employment has ended, seek assistance promptly: some dismissal applications have short deadlines.
