Here is the
policy on how the investigations are to be conducted. The incentive they're given is 35% off some insurance costs. So, you know they'll accept it.
If were charged, I would say nothing without being represented in some way, even if innocent. In reading the procedures of how the investigation goes, you're already presumed guilty and subject to a polygraph and such. Even if I was found innocent, I think I'd leave the company anyway. I'd be real uncomfortable working environment.
