If there is a problem that led to the departure of an employee, that problem won’t go away just because your company did the equivalent of closing your eyes, plugging your ears and chanting, “I can’t hear you. I can’t hear you.” Problems left unchecked will ripen into a full blown crisis at a later date. By being proactive, the information you learn in an exit interview can be used to conduct an investigation while memories are fresh and there is an opportunity to minimize your legal exposure.
