Workplace issues are inevitable in any organization; some more complex and fraught with liability than others. What differentiates high-performing, low-risk employers from vulnerable ones is how they respond when those issues arise. At the center of that response is one of the most important processes an organization can deploy: the workplace investigation.
What is a Workplace Investigation?
A workplace investigation is a formal, structured process used to examine concerns or allegations raised within an organization. It involves gathering facts, interviewing involved parties, reviewing evidence, and determining whether a company policy or law has been violated. Investigations may be triggered by a range of issues, including:
- Harassment or discrimination allegations
- Retaliation complaints
- Conflicts or bullying
- Ethics and policy violations
- Wage and hour disputes
- Safety or conduct concerns
- Misuse of company assets
- Interpersonal disputes with unclear facts
The goal of an investigation is two-fold:
- Protect the organization by acting quickly and responsibly when a concern arises.
- Ensure fairness by objectively and thoroughly determining what occurred and what action, if any, should be taken.
In today’s climate, investigations are not optional. Once an employer becomes aware of a potential issue, they have a duty to take prompt, appropriate action. Failing to do so can expose your organization to significant legal and reputational consequences.
The Complexity of Modern Workplace Investigations
Although the concept of conducting an investigation sounds straightforward, real investigations rarely are. Cases often involve conflicting stories, emotional distress, multiple witnesses, or allegations touching several layers of the organization. What appears to be a simple “he said, she said” issue can become a costly, credibility-damaging problem in the hands of an untrained investigator.
All you need do is refer to a 2025 SHRM lawsuit for examples.
Several challenges commonly complicate internal investigations:
1. Perceived or Actual Bias
Employees expect impartiality, and they are vocal when they suspect otherwise. If an internal investigator has any historical connection with the complainant, respondent, witnesses or involved leaders, the investigation may be viewed as biased. Even if the process is fair, the perception of partiality can undermine the entire outcome.
2. Inadequate Training
HR professionals are skilled in employee relations, but many are not trained investigators. Workplace investigations demand specialized interviewing techniques, credibility assessments, and documentation standards. Small missteps, such as leading questions or overlooked inconsistencies, can be dissected in subsequent litigation.
3. Insufficient Documentation
Courts often believe that, if it is not written down, it did not happen. Organizations routinely face challenges because timelines are incomplete, interview notes lack detail, or key evidence is not preserved. Poor documentation can invalidate an otherwise sound investigation.
4. Heightened Legal and Reputational Risk
A flawed investigation can:
- Escalate retaliation claims
- Strengthen discrimination or wrongful termination cases
- Undermine affirmative defenses
- Invite regulatory scrutiny
- Damage internal trust among employees
- Create public relations vulnerabilities
In short: the consequences of getting an investigation wrong are far more severe than most organizations realize.
When Internal Investigations May Not Be the Best Approach
While some issues can be handled in-house, the following situations almost always warrant external support:
- Allegations involving HR, leadership, or senior executives
- Complaints from or about protected classes
- Claims expected to lead to discipline or termination
- High-conflict or emotionally charged allegations
- Repeated complaints involving the same individuals or departments
- Cases where confidentiality concerns are already present
- Situations likely to escalate to legal counsel or regulatory review
Internal HR should never be placed in the position of investigating their own decisions or those of their leaders. Doing so creates risk for both the organization and the employees involved.
Why Third-Party Investigators Are a Strategic Imperative
Engaging an outside investigator is no longer viewed as a last resort. It is a standard best practice, especially in cases involving heightened risk, sensitive allegations, or potential conflicts of interest.
1. Independence and Credibility
Third-party investigators bring neutrality that internal staff cannot. They have no stake in the outcome, no historical relationships, and no influence by organizational politics. This independence significantly reduces the likelihood of bias claims and strengthens trust among employees.
2. Expertise in Handling Complex Allegations
External investigators are trained specifically for these situations. They know how to:
- Conduct trauma-informed interviews
- Uncover inconsistencies that internal staff may not notice
- Evaluate credibility objectively
- Navigate uncooperative or emotional witnesses
- Manage sensitive or high-profile cases
- Their experience leads to more precise, defensible findings.
3. A Legally Defensible Process
When a case escalates to litigation, documentation and methodology matter. Third-party investigators produce structured, comprehensive reports aligning with EEOC and industry best practices, making the findings more credible to attorneys, regulators, and courts.
4. Enhanced Employee Trust
Employees are more likely to speak openly when they know the investigator is not connected to management. This typically results in clearer facts, better cooperation, and more reliable outcomes.
Why Executives Should Be Paying Attention
CEOs, CFOs, and other senior leaders often are unaware of the full scope of risk tied to workplace investigations. What seems like a minor internal issue quickly can become a significant business liability if mishandled.
- A poor investigation can:
- Erode trust at all levels of the workforce
- Lead to litigation, resulting in the expenditure of money, time and energy
- Trigger reputational damage that affects customers, donors, or partners
- Disrupt operations and productivity
- Undermine leadership’s credibility
- A strong investigation, in contrast:
- Protects the organization and its people
- Demonstrates leadership responsibility
- Builds trust in HR processes
- Reduces exposure
- Positions the organization as proactive and fair
In today’s environment, the question is no longer “Do we need to conduct an investigation?” It is “Are we prepared to conduct a defensible one?”
Building a Culture of Accountability and Trust
Organizations that invest in skilled, objective investigations build cultures where concerns are taken seriously and resolved fairly. Employees feel heard. Leadership feels protected. Risk is reduced.
Third-party investigators reinforce this message: “We will get to the truth, and we will do it the right way.”
That message matters legally, ethically, and operationally.
