When something goes wrong at work, whether it’s bullying, misconduct or discrimination, most businesses don’t run into trouble because of the issue itself.
It’s how they handle it that causes the real problems.
If you’re an Australian CEO, founder or HR leader, this is one of those situations where the process matters just as much as the outcome. Get it wrong and you could be dealing with unfair dismissal claims, reputational damage or even regulators getting involved.
Get it right and you protect your people and your business at the same time.
How to identify a HR Problem
Most workplace investigations don’t fall apart at the tail end. They go off track right at the beginning.
We see it all the time. HR tries to manage things internally without legal input. Someone has already made up their mind about the outcome. Key steps aren’t written down. The employee at the centre of it all doesn’t get a proper chance to respond.
On the surface, it might look like something was done. However, when properly assessed from a legal perspective, the process is unlikely to withstand scrutiny in a court of law.
Why a Fair Process Matters
A poorly handled investigation can lead to unfair dismissal claims, adverse action or discrimination claims, and defamation or privacy issues.
Courts and tribunals often focus more on how you handled the situation than what you ultimately decided. So even if there was genuine misconduct, a messy or unfair process can still land you in trouble.
How to run an investigation properly (and protect your business)
1. Get legal guidance early
One of the biggest mistakes businesses make is waiting too long to involve lawyers.
Early legal help helps you set things up properly from day one, protect sensitive communications and avoid missteps that are hard to undo later. It is also more cost-effective at this stage, as getting the right advice early can help avoid costly legal disputes down the track. Businesses often call us after they’ve already terminated an employee based on a workplace investigation, often when the risk is already real.

2. Be fair
Being fair isn’t just a “nice to have”. It’s essential. At a minimum, employees must be clearly told what the allegations are and have a genuine opportunity to respond. Importantly, their defence or version of events must be assessed without bias or pre-judgment. Even if the evidence feels strong, a process that looks rushed or one-sided won’t stand up.
3. Keep things confidential
Investigations can quickly spiral if information starts spreading around the workplace. Poor confidentiality can lead to defamation claims, internal conflict, loss of trust across teams and actually undermine your investigation process. This is particularly important when deciding if witness accounts are needed.
Internal investigators should limit access to a strict “need-to-know” basis and store documents securely. For more sensitive matters, it might also make sense to bring in an external investigator.
4. Write everything down and be clear
If your decision is ever challenged, your documentation becomes your safety net (i.e. your defence). You should be recording everything, including what evidence was considered, who was interviewed and what they said, how decisions were made and the reasoning behind any outcome.
If it’s not documented, it is much harder to prove it occurred, especially when burden shifts to you in a fair work dispute.
5. Don’t drag it out, but don’t rush it either
Delays frustrate everyone involved and can escalate complaints. But moving too fast creates risk. A good investigation strikes a balance with a clearly defined timeline and regular updates to all parties involved.
6. Have the right foundations in place
The safest investigations start long before any complaint is made. Your business should already have a clear investigation procedure and up-to-date workplace policies (like an anti-bullying or harassment policy). It’s also critical to train your managers so that they know how to respond effectively if the time comes.
Without this, every investigation becomes reactive and that can increase your risk.
A real-world example of what can go wrong
A financial services business received a racial harassment complaint. Instead of seeking legal guidance, HR ran the investigation internally, skipped key procedural steps (like providing the employee a reasonable chance to respond) and terminated that employee in less than a week.
This resulted in the employee submitting an unfair dismissal claim, and winning. What went wrong wasn’t just the termination decision. It was how the investigation was handled. With earlier legal advice, the employer could have ensured the investigation process complied with the Fair Work Act 2009 (Cth).
CEO & HR Investigation Risk Assessment Checklist
If you’re about to run an investigation, pause and check:
- Have we involved legal counsel early?
- Is the investigator independent and unbiased?
- Has the employee been given a fair chance to respond?
- Are we keeping everything confidential?
- Are we documenting every step clearly?
- Are we working within a reasonable timeframe?
- Are our policies actually up to date?
If any of these are a “no” or “not sure”, that’s usually where your risk sits, and it is best to contact us to discuss how we can help you through the process.
Where Performance Management Fits In
Many investigations overlap with performance issues. Handled poorly, performance management can quickly turn into unfair dismissal claims or adverse action risks
To reduce your exposure you should set clear expectations early, provide genuine support to improve performance (not just warnings with no real guidance for an employee). Be sure to document your conversations and any performance improvement plans proposed or implemented. Remember to give your employees a real opportunity to improve.
Get the Process Right from the Start
HR investigations can be high-pressure and emotional. They’re not just about resolving a staff complaint, they’re about protecting your business from avoidable issues.
In most cases, the difference between a clean outcome and a costly dispute comes down to one thing: whether the process was handled properly from the start?
If you’re dealing with a workplace issue and want to get it right the first time, getting early legal guidance can make all the difference. A short conversation upfront with one of our experienced employment lawyers can prevent months of stress and costs.
Frequently Asked Questions (FAQs)
Why are HR investigations legally risky?
Because they directly affect employees and employees have strong protections under the Fair Work Act. If the process isn’t fair or properly handled, it can lead to claims even if your intentions were good.
Should we always use an external investigator?
Not always. But for serious matters, especially involving senior staff or sensitive allegations (like sexual harassment), an independent mind can help reduce bias and strengthen your business’s defensibility.
Can an employee challenge the outcome?
Yes, and it happens often. If the process is flawed in any way, they can still bring a claim even if the outcome might seem justified. Speak to one of our experienced employment lawyers to ensure you are in the best position.
