Frequently Asked Questions
Find answers to your most pressing questions about our services and processes.
What is a workplace investigation?
A workplace investigation is a structured fact‑finding process used to explore allegations such as misconduct, bullying, discrimination, whistleblowing or policy breaches. An impartial investigator gathers evidence, interviews witnesses and prepares findings to support fair and informed organisational decisions.
When is an external investigator appropriate?
An external investigator is particularly valuable when allegations involve senior employees, HR or managers, or where internal staff have conflicts of interest. It is also appropriate where the issues are legally or factually complex, where there are multiple complainants or witnesses, or where impartiality could reasonably be questioned. Bringing in an independent investigator strengthens the credibility of the process and reduces both legal and reputational risk.
What are the benefits for employers?
Engaging an external investigator offers employers truly independent and impartial fact‑finding, reducing the risk of procedural flaws and supporting stronger decision‑making. It ensures sensitive or contentious issues are handled by an experienced employment lawyer, improves the credibility of the process, and results in clear, defensible reports that align with legal and policy standards. It also relieves pressure on HR teams who may lack the time, capacity or neutrality required for complex matters.
