If you blow ANYTHING other then .000 or test positive for ANYTHING you are into the Substance Abuse rules. The IAM CBA has nothing in it to protect you. Quite simply, if you test positive at any level for anything prohibited in both samples (or in the case of alcohol a second breathalizer) and it can not be legitimatly substantiated (I've heard of dentists in certain countries using cocaine instead of novicaine) you're gone, end of file. All the CBA does is require a second test, which AWA always had, though I don't know about USA. If you're drunk or high, don't come to work. If you do and you get randomed or reasonable suspissioned, you're gone. The Union can fight as hard as you want, but if you were under the influence you're in for a hell of a shock when you come off your high.
