When a harassment complaint lands on your desk, or you suspect serious misconduct, your next steps matter more than you might think. Handle it poorly, and you risk unfair dismissal claims, damaged workplace culture, and substantial legal costs. Handle it well, and you’ve protected everyone involved.
A workplace investigation is a structured, impartial process that gathers facts about alleged misconduct or policy breaches. It’s not about proving guilt — it’s about determining, on the balance of probabilities, whether the allegations can be substantiated so you can make fair, informed decisions.

When Does Your Business Need a Workplace Investigation?
Not every workplace complaint requires a full investigation, but certain situations demand it. You’ll need to investigate when allegations involve serious misconduct, potential legal violations, or could impact your business operations and reputation.
Common triggers include harassment or discrimination based on protected attributes like age, gender, race, or disability. Research shows nearly 30% of Australian workers experienced discrimination or harassment in 2023, making these investigations increasingly necessary.
Other situations requiring investigation include workplace health and safety concerns, breaches of company policies, allegations of dishonesty or fraud, and serious behavioural issues that affect team morale or productivity. If you’re considering terminating someone’s employment based on allegations, an investigation is essential, both legally and ethically.
Why Engaging a Professional Investigator Protects You
The stakes are high when investigating workplace complaints. Make a biased decision, skip procedural fairness, or miss critical evidence, and you’ve opened your business to unfair dismissal claims with the Fair Work Commission.
Professional workplace investigators bring critical advantages that internal investigations often lack. They’re genuinely impartial — no workplace relationships clouding their judgement, no pressure to protect certain employees or rush to conclusions that favour management.
They apply natural justice principles consistently, ensuring both the complainant and respondent receive fair treatment. This means giving employees a genuine opportunity to respond to allegations, making decisions based on evidence rather than assumptions, and maintaining confidentiality throughout the process.
Perhaps most importantly, experienced investigators document everything properly. Their comprehensive reports stand up under legal scrutiny, providing clear reasoning for their findings and recommendations. This documentation becomes invaluable if a dispute escalates to workers’ compensation lawyers or Fair Work proceedings.
What Happens During a Workplace Investigation
Understanding the investigation process helps businesses prepare properly and demonstrates to staff that complaints are taken seriously.
1. Review
The investigator reviews the initial complaint to determine whether a formal investigation is warranted. They’ll familiarise themselves with your policies and procedures, ensuring the process aligns with your workplace requirements and legal obligations.
2. Interviews
Interviews follow a structured approach. The investigator speaks with the complainant first, understanding their concerns in detail. Witnesses are interviewed separately to gather supporting evidence or alternative perspectives. Finally, the respondent receives formal allegations in writing and has the opportunity to respond fully.
3. Record
Throughout this process, investigators maintain detailed records of all interviews, evidence reviewed, and decisions made. The Fair Work Ombudsman emphasises the importance of thorough documentation in workplace investigations, particularly when compliance issues arise.
4. Report
The investigation concludes with a comprehensive report that outlines the findings, explains the reasoning behind the conclusions, and recommends appropriate next steps. These might include no further action, mediation, training, policy changes, or disciplinary measures.
