Out of interest, what is the exact language in the F.O.M.? Does it specifically say that a B.A.C. greater than 0.2 will result in termination or does it just say disciplinary action?
I have seen language where if you witness someone drinking within the company cut off and don't rat him / her out, you too are subject to termination.
Hell of a situation to be in. Can't say I blame the slam clickers.
