we had a guy like that, here. he was an ISP (Contractor) I got so fed up that i banned him from accessing the server. This caused quite a commotion i tell you. As all of the other ISP's were in a bit of a fret. "This is the way we always worked" they'd say. No it wasnt would be the reply, you were just let get on with it running rough shod over the CAD standards. My argument (which was upheld by senior magement) was if we got a contractor to come into our buidling and install or do some remidial works we would want him to do it to a particular standard (ie the building regualtions at least) if he did not do that, then he either repaired the work or he wasnt paid. And he wasn't paid anymore money if he needed to repair it. So, in far as reasonalby practical, adhereance to the CAD standards they are all behaving themselves now. Any deviation from the CAD standards needs to be preagreed and resonable justifaction must be provided prior to any deviation.
