What can a Wife do 2 a "woman" who slept with her husband that took inventory from the wife's store 4 payment?

Nasty but true. This woman was getting paid in video games for , and she works at a public school. Yes the wife is going to get a divorce from this guy, but she wants to know what if anything can be done to let her know YES I know what you were doing, the wife has all the evidence, and she should think twice before doing something so crackhead-ish again.
