What AI Should Never Do in a Workplace Investigation
By Amy Hagan, Founder of HR Does AI
I've conducted more than 150 workplace investigations. I use AI in my work. And I can tell you exactly where the line is.
AI is useful in an investigation. It is not an investigator.
Where AI earns its place
Investigations generate a lot of material, and organizing it well is half the battle. Used in an approved, secure tool, AI can help you:
- Turn a messy complaint into a structured list of allegations
- Build a chronology from emails, texts, and interview notes
- Flag gaps, such as a date no one has explained or a witness no one has interviewed
- Draft interview topics based on the investigation plan you approved
- Check a draft report so every factual statement points back to a source
That's real time saved, and it often improves consistency.
Where AI does not belong
Credibility. Deciding who is more believable means weighing demeanor, corroboration, inherent plausibility, motive, and past record. That is a trained human judgment, and it's the heart of the work.
Findings. Whether an allegation is substantiated under the applicable standard is the investigator's call, reasoned from the evidence. An AI-generated conclusion is not a finding. It's a guess with good grammar.
The interview itself. Follow-up questions, silence, tone, and the moment a witness hesitates all require a person in the room.
Scope and strategy. Who to interview, in what order, and what's in or out of scope depends on context, conflicts, and legal considerations a tool can't see.
The confidentiality question
Before any of this, ask where the information is going. Witness statements, medical details, and personnel records don't belong in a public AI tool. If your organization hasn't approved a tool and set data rules for investigation work, that's the first problem to solve.
A simple test
The standard I use: if you would have to defend it under oath, you have to have done it yourself.
AI can help you organize the evidence. You weigh it, you reach the finding, and you own every word of the report. That isn't a limitation of the technology. It's what makes an investigation fair, impartial, and defensible.
