What is Show cause?

Updated 24 Aug 2026 5 min read

A show-cause process asks an employee to explain — to "show cause" — why disciplinary action, often dismissal, should not be taken against them. It is issued after an allegation has been investigated, sets out the findings and the action being considered, and gives the employee a defined period to respond before any decision is made.

This glossary article about show cause provides general information about Australian employment law and workplace practices. It does not constitute legal, HR, or professional advice and should not be relied on as a substitute for advice specific to your business, workforce, or circumstances.

What "show cause" means

A show-cause process asks an employee to explain why disciplinary action — usually dismissal — should not be taken against them. It arrives after an allegation has been investigated, not before: the employer states what it has found, names the action it is contemplating, and gives the employee a defined period to respond.

The phrase is borrowed from legal procedure, and the borrowing is apt. The burden shifts to the employee to answer a case that has already been put.

When it is used

  • Serious misconduct where dismissal is a realistic outcome — theft, safety breaches, harassment findings.
  • After a failed improvement process, where a performance improvement plan has run without the required change.
  • Repeated conduct already the subject of warnings.

It is not the right instrument for a first, minor issue — that is a conversation or a warning. Reaching for show cause too early reads as a decision already taken.

What the letter contains

The six elements

  • The specific allegation, and the findings so far
  • The policy, standard or term said to have been breached
  • The action being considered, stated plainly
  • An invitation to respond, with a reasonable deadline
  • Notice that a support person may attend any meeting
  • A statement that no decision has been made

Why it matters legally

It is evidence, not a legal requirement

No law requires a show-cause letter. What the Fair Work Commission does weigh is whether the employee was notified of the reason for dismissal and given a genuine opportunity to respond — and a show-cause letter proves both in one document. That is its entire value, and it is a large one.

Common mistakes

Vague allegations

"Concerns about your conduct" cannot be answered, so the opportunity to respond is not genuine.

A deadline nobody could meet

Same day, or over a weekend, signals the decision was already made.

Announcing the outcome in the letter

If the letter reads as a dismissal notice, it is one — and the process was theatre.

Not recording the response

Without a note of what was said and why it did not change the outcome, the consideration is unprovable.

Key takeaways

  • Show cause asks the employee to explain why action should not be taken, after an investigation.
  • It is not legally required — its value is proving notification and a genuine chance to respond.
  • Be specific about the allegation and honest that no decision has been made.
  • Give a deadline a person could realistically meet, and allow a support person.
  • Record the response and the reasoning. That record is the point.

What the Commission actually weighs is set out in the unfair dismissal guide, and the process end to end in how to terminate an employee fairly.

A show-cause process is only worth as much as the record it leaves. RosterElf keeps the allegation, the response and the decision against the employee, so the file exists before anyone asks for it.
