What to Do (and Not Do) When Interviewing a Worker After an Incident

When something goes wrong on a job site, the first interview you conduct often shapes everything that follows — the investigation, the claim, and sometimes the appeal. Get it right, and you have a clear, defensible record. Get it wrong, and you're left with inconsistent statements, a frustrated worker, and a claims process that takes far longer than it needs to.

Most supervisors have never been formally trained to do this. They're handed the responsibility the moment an incident happens, with no framework for how to ask the right questions or capture the right information. This post covers the basics — and the mistakes we see most often.

Why the First Interview Matters So Much

Memory fades fast, and it fades unevenly. A worker's recollection of what happened in the seconds before and after an incident is sharpest in the first few hours. Wait a day, and details blur. Wait a week, and you're often working with a reconstructed version of events rather than what actually happened.

This isn't just about accuracy for its own sake. A well-documented, timely interview is often the single strongest piece of evidence in a WCB claim — for the worker and for the employer. It protects both sides.

Common Mistakes That Undermine the Process

Leading questions. Asking "you weren't wearing your harness, were you?" instead of "walk me through what safety equipment you had on" shapes the answer before the worker even speaks. It also creates a record that can look coached or unreliable later.

Assuming fault before the facts are in. An interview conducted with a predetermined conclusion in mind tends to miss details that don't fit that conclusion — and workers pick up on that tone quickly, which makes them less forthcoming.

Skipping witnesses. The injured worker's account matters, but it's rarely the whole picture. Witnesses often notice things the worker themselves couldn't see or doesn't remember under stress.

No written record, or an incomplete one. A conversation that isn't documented in detail is a conversation that didn't really happen, as far as a claims adjudicator is concerned. Notes taken after the fact, from memory, are far weaker than notes taken during or immediately after the interview.

What a Proper Interview Structure Looks Like

At a high level, an effective post-incident interview:

• Happens as soon as possible after the incident, ideally the same day, hopefully within the hour or as soon as possible.

• Uses open-ended questions ("what happened," "what did you see") rather than yes/no prompts

• Is conducted in a neutral, non-accusatory tone

• Includes every witness, not just the injured worker

• Is documented in writing, with direct quotes where possible, signed and dated

  
  

None of this requires assuming who's at fault. It requires capturing what actually happened, as completely and neutrally as possible, while the details are still fresh.

How This Connects to Everything Downstream

The interview isn't a standalone task — it's the foundation for the claims process that follows. A thorough, well-documented interview makes claims management faster and more accurate. A rushed or poorly handled one tends to create disputes, delays, and sometimes appeals that could have been avoided.

If you're the person responsible for this in your organization, it's worth treating the interview process as seriously as any other safety-critical procedure — because that's effectively what it is.
