A workplace investigation report should document the process, evidence considered, and the reasoning
behind findings so a decision-maker can act fairly and defensibly. A report that repeats statements and then jumps to conclusions is hard to rely on and increases organisational risk.
Why the report is the high-risk part
The report is the organisational record of what was done and why. If the matter escalates into an unfair
dismissal, general protections, discrimination, WHS or reputational dispute, the report is often one of the
first documents scrutinised. A weak report doesn’t just fail to help – it creates risk.
What a good report usually contains
A defensible report shows its working. At minimum, it should set out the scope, the process followed, the
evidence considered, the evidentiary standard used, and findings on each allegation.
It should also make clear any limitations (for example, witnesses unavailable, evidence not accessible, or
scope constraints) so a decision-maker understands the edges of the conclusions.
Balance of probabilities – and why serious matters need stronger evidence
Most workplace investigations apply the civil standard: balance of probabilities. Practically, the more serious the allegation and consequences, the stronger and clearer the evidence should be before making an adverse finding.
This is where many internal reports fail – they state conclusions without showing the evidentiary basis and reasoning.
Credibility analysis: the part you can’t skip
Where evidence conflicts, your report needs to explain why one account was preferred. That might involve consistency over time, plausibility in context, corroboration, contemporaneous documents, or motive to mislead.
A report that simply repeats witness statements and then declares an outcome is vulnerable to challenge
because it doesn’t explain how the conclusion was reached.
Quick self-check: is your report usable?
If your report doesn’t clearly state allegations, identify key evidence, explain how evidence was weighed,
and provide findings on each allegation, a decision-maker will struggle to rely on it confidently.
That’s usually where organisations end up re-running investigations or settling disputes they should have
been able to manage.
FAQs
Should an investigation report include recommendations?
Many organisations separate findings from recommendations so the fact-finding remains clean.
Recommendations can be provided separately if needed.
Who should receive the investigation report?
Typically the authorised organisational representative and decision-maker. Access should be controlled to protect confidentiality.
Can participants see the whole report?
It depends on organisational practice and legal context. Many organisations provide an outcome summary rather than the full report.
