HR Acuity’s CEO and Founder, Deb Muller, recently moderated our expert webinar, “Making the Call: How to Assess Credibility in Workplace Investigations.” Our guest, Beth Gramigna, an employment attorney and the Founder of Tribu Partners, discussed in detail what to look for when trying to determine who is telling the truth in a workplace investigation.
Using a fictional case, Beth walked our near-record number of attendees through the various stages of the investigation, including interviewing the fictional complainant, her manager and several witnesses, and the findings that resulted from those interviews. This juicy case sparked much engagement with our attendees who asked interesting, thought-provoking questions that Beth answered throughout the webinar, as well as offering her some “takes” of their own!
Here are three highlights from the webinar, but we encourage you watch the entire replay of the webinar here:
- Investigations aren’t just about fact-gathering. The investigator’s role is to assess credibility based on all interviews so that the decision-maker can make an informed decision. The analytical standard for assessing credibility takes the following into account:
- Is there a preponderance of evidence based on corroborating information?
- Did the event more than likely occur?
- Does the evidence presented on one side outweigh what’s presented on the opposing side?
- Is there a greater than 50% chance that a proposition is true
Insufficient evidence is almost always the factor leading the investigator to conclude it’s impossible to make a call – the very thing that is most needed. That’s
when the investigator needs to go back and ask more questions.
- Pitfalls in determining credibility:
- Confirmation bias – you know the parties, or you stop investigating because of investigator bias – you’ve decided that you think something happened in a certain way. There may also be internal bias to get the investigation completed.
- Making a determination too soon – without having sufficient information.
- Failing to make a determination – also a case where you haven’t obtained enough information. You will need to ask more questions or talk to more witnesses.
- The most reliable credibility factors (Gold Standard) when you’re struggling to decide who is telling the truth:
- Corroboration – witness testimony, text message or email exchanges, video or photo evidence, also assessing reliability of testimony with a witness’s recollection of events
- Consistency – Is there witness testimony or physical evidence that is consistent with the complainant’s testimony? Or are there inconsistencies that make you doubt credibility?
- Inherent plausibility – Does the testimony make sense? Which version of the events seems more plausible? Is there a plausible reason for inconsistencies (ex., an employee tells a manager one story because the manager is really the issue in the investigation)?
- Motive to falsify – Is there motivation to lie (fear of retaliation, a witness who wants to protect someone, etc.)?
- Material omission – Did someone omit something that was important, despite having an opportunity to provide the information?
These are just some of the highlights of the webinar, but you’ll want to watch the complete webinar on-demand here – everyone can use a refresher on the topic of how to best assess credibility in investigations!
