When to Use an External Workplace Investigator

There are circumstances where managing a workplace matter internally is not the most effective or appropriate approach.

This is particularly the case where independence, impartiality or perceived fairness may be called into question.

In local government and public sector environments, workplace matters are rarely simple. They often involve multiple stakeholders, complex relationships and a heightened level of scrutiny — both internally and externally. Even where internal capability exists, there are situations where the involvement of an external investigator is not just beneficial, but necessary.

Perceived Bias

One of the most common indicators is perceived bias.

Even where an internal investigation is conducted with complete professionalism, the perception of bias can undermine the outcome. This is particularly relevant where the individuals involved are known to the investigator, or where there is an existing reporting relationship. In these situations, independence is not just about actual fairness — it's about maintaining confidence in the process.

In many cases, organisations wait until a matter becomes more complex before seeking external support. In reality, early involvement can often reduce risk and simplify the process significantly.

Senior Employee Matters

Another scenario is where the matter involves senior employees or leadership.

Investigating matters at this level can create discomfort and risk within an organisation. It may not be appropriate or practical for internal staff to manage these investigations, particularly where there are power dynamics or reputational considerations involved.

An external investigator removes that complexity, allowing the matter to be handled objectively and without internal pressure.

Capacity Constraints

Capacity is another factor that is often overlooked.

Workplace investigations require time, structure and attention to detail. They involve interviews, evidence gathering, documentation and procedural fairness considerations. For organisations already managing operational demands, dedicating the necessary time to conduct a thorough investigation can be challenging.

In these cases, external support allows the organisation to maintain focus on day-to-day operations, while ensuring the matter is managed appropriately.

Managing Risk

There is also the issue of risk.

Where a matter has the potential to escalate — whether through formal complaints, legal proceedings or reputational exposure — the way it is handled becomes critical. A structured, well-documented investigation process can significantly reduce risk and provide clarity around outcomes.

Beyond individual matters, there is a broader organisational benefit to using external investigators in the right circumstances. It sends a clear message that the organisation is committed to fairness, transparency and accountability. This can have a positive impact on culture, trust and confidence across the workforce.

When to Consider External Support

That said, not every matter requires external involvement. Many employee relations issues can and should be managed internally. The key is recognising when a matter moves beyond routine management into something that requires a different level of structure, independence or expertise.

As a guide, it is worth considering external support when:

• The matter is sensitive or high-risk
• Independence is important (or likely to be questioned)
• Senior employees are involved
• Internal capacity is limited
• There is potential for escalation

Ultimately, the decision to engage an external investigator is less about capability, and more about context.

It is about ensuring that the process is not only fair, but seen to be fair.

And in many cases, that distinction makes all the difference.
