Workplace Bullying & Harassment Investigations: Employer Responsibilities

Few things land on a manager's desk that feel as heavy as a bullying or harassment complaint. There's the wellbeing of the person who's come forward, the rights of the person being accused, the rest of the team watching how it gets handled, and somewhere underneath all of that, a genuine legal obligation that doesn't go away just because the situation feels awkward or uncertain.

If you've ever sat across from an employee who's just told you they're being bullied by a colleague or manager, you know that gut feeling. Part of you wants to handle it quietly and quickly. Part of you isn't sure where to start. And part of you is wondering whether you're about to make things worse no matter what you do.

This is exactly where a lot of Australian businesses get into trouble, not because they don't care, but because they don't have a clear, defensible process for actually investigating what's happened. Complete Corporate Services has spent close to four decades helping Australian employers handle workplace investigations properly, including bullying and harassment matters, and this guide walks through what your responsibilities actually are and how a professional, independent investigation protects everyone involved.

Why This Isn't Something You Can Just Let Slide

It's tempting, especially for smaller businesses, to hope a bullying complaint will resolve itself. Maybe the two people involved just need some space. Maybe it's a misunderstanding that will blow over. Sometimes that's true. Often it isn't, and ignoring the issue or handling it informally creates real legal exposure.

Under Australian work health and safety law, employers have a duty of care that extends to psychological wellbeing, not just physical safety. Bullying and harassment fall squarely within this. If a complaint is raised and the employer doesn't take it seriously, doesn't investigate properly, or handles it in a way that's clearly unfair to either party, the business can end up facing a Fair Work Commission stop bullying order, a workers compensation claim for psychological injury, an unfair dismissal claim if someone is let go without proper process, or in more serious cases, a general protections claim.

None of these outcomes are good for the business, and all of them are far more likely when an investigation is rushed, biased, or simply never happens at all.

What Counts as Workplace Bullying or Harassment

It helps to be clear on definitions here, because not every workplace conflict is bullying, and getting this wrong in either direction causes problems. Bullying generally involves repeated, unreasonable behaviour directed at a worker, or group of workers, that creates a risk to health and safety. This might look like constant criticism delivered in a demeaning way, exclusion from meetings or information needed to do the job properly, unreasonable work demands designed to set someone up to fail, or spreading rumours and gossip intended to damage someone's standing.

Harassment, meanwhile, often relates to a protected attribute, such as sex, race, disability, age or sexual orientation, and includes unwelcome conduct that a reasonable person would find offensive, humiliating or intimidating. Sexual harassment specifically carries its own legal framework under the Sex Discrimination Act and recent positive duty obligations introduced under the Respect at Work reforms.

It's also worth saying clearly that reasonable management action, carried out fairly, isn't bullying. A manager giving honest, constructive performance feedback, or making a fair decision about rosters or workload, isn't the same as bullying, even if the employee on the receiving end is unhappy about it. This distinction matters enormously, and it's part of why an independent, properly conducted investigation is so valuable. It separates genuine misconduct from ordinary workplace friction or legitimate management decisions.

Your Obligations as an Employer

Once a complaint has been raised, formally or informally, you have a genuine legal obligation to act. This doesn't necessarily mean launching a full formal investigation for every single complaint, but it does mean taking the concern seriously, assessing it properly, and responding in a way that's proportionate to what's being alleged.

At a minimum, this involves acknowledging the complaint and taking it seriously rather than dismissing it. It means assessing whether the matter needs a formal investigation or can be resolved through informal conflict resolution, and if a formal investigation is warranted, ensuring it's conducted fairly, impartially, and without unnecessary delay. You also need to protect the complainant from victimisation throughout the process, keep matters confidential wherever possible, and ultimately document everything thoroughly in case the matter ever needs to be defended at the Fair Work Commission or elsewhere.

This is a lot to get right, especially for businesses without a dedicated HR function. Many small and medium Australian businesses simply don't have someone on staff who has the training, time, or genuine independence to run a fair investigation, and that's precisely where engaging an external investigator becomes so valuable.

Why Internal Investigations Often Go Wrong

There's a reason workplace investigations conducted entirely in-house frequently end up being challenged. The person conducting the investigation often knows both the complainant and the accused, sometimes quite well. They may have a working relationship with one or both parties that makes genuine neutrality difficult, even with the best of intentions. They might also lack training in proper investigative method, things like how to conduct a structured interview, how to weigh conflicting accounts, or how to gather and preserve evidence in a way that holds up.

There's also a subtler problem. Employees often don't trust that an internal investigation will be fair, particularly if the person investigating reports to the same manager as the person accused, or has an existing relationship with either party. This lack of trust can mean people hold back information, refuse to fully cooperate, or feel the outcome was predetermined regardless of what actually gets found.

An external, independent investigator removes all of these issues. There's no prior relationship clouding judgement, no internal politics influencing the outcome, and a genuinely impartial process that both the complainant and the accused can have confidence in, regardless of which way the findings ultimately go.

How a Professional Workplace Investigation Actually Works

When CCS is engaged to conduct a workplace bullying or harassment investigation, the process is structured, fair, and thorough. It typically begins with a confidential scoping conversation to understand exactly what's being alleged, who's involved, and what evidence or documentation already exists.

From there, a clear terms of reference is established, setting out precisely what the investigation will examine. This matters because investigations that drift beyond their original scope often become unfair to the people involved and harder to defend later. Interviews are then conducted with the complainant, the accused, and any relevant witnesses, using structured questioning techniques designed to gather accurate, consistent accounts rather than leading or suggestive questioning.

Throughout the process, evidence is gathered and properly documented, which might include emails, messages, rosters, performance records, or witness statements. Where findings are reached, they're based on the balance of probabilities, the standard used in workplace investigations, and are clearly documented in a way that explains how each conclusion was reached. Finally, a comprehensive report is provided to the business, setting out the findings and, where appropriate, recommendations for next steps.

Throughout all of this, confidentiality is maintained as much as possible, and both parties are treated with genuine procedural fairness, meaning they each get a proper opportunity to respond to allegations made against them before any findings are finalised.

Beyond the Investigation Itself

Handling an individual complaint properly is only part of the picture. CCS also works with businesses on the broader systems that prevent bullying and harassment from becoming entrenched in the first place. This includes developing or updating codes of conduct covering discrimination, bullying, harassment, and equal opportunity, along with anti-discrimination training for employees and management on diversity, inclusion and respectful workplace behaviour.

It also extends to reviewing how policies are actually communicated and understood across the business, not just whether they exist on paper, and conducting audits to check whether existing policies and procedures are actually working in practice. For businesses that want a genuinely proactive approach, this also includes broader work health and safety planning that treats psychosocial risks, things like bullying, harassment, excessive workload and fatigue, with the same seriousness as physical safety hazards, which is now an explicit requirement under most state and territory WHS legislation.

What Happens If You Get This Wrong

The cost of mishandling a bullying or harassment complaint extends well beyond the immediate situation. A poorly handled investigation can result in the original complainant pursuing a claim against the business for failing in its duty of care, the accused employee challenging any disciplinary outcome as procedurally unfair, particularly if they weren't given a proper chance to respond, broader damage to workplace morale and trust if staff perceive the process as biased or dismissive, and reputational harm if the matter becomes public, which increasingly happens given how openly workplace issues are now discussed.

There's also a quieter cost that's easy to underestimate. Good employees, the kind you actually want to keep, are watching how these situations are handled. A business that's seen to take complaints seriously and handle them fairly tends to retain trust and loyalty even through a difficult process. A business that's seen to sweep things under the rug, or conversely, that's seen to throw an accused employee under the bus without a fair process, tends to lose trust from the entire team, not just the people directly involved.

Getting It Right From the Start

If you're currently dealing with a bullying or harassment complaint, or you simply want to make sure your business has a proper process in place before something arises, the most important step is getting independent, experienced support involved early.
