Thanks annieo,
I was off last Friday and when I came in on Monday found out that another manager (not with my company - but is in charge of the final phase and handover of the project) got wind of what happened and called a bunch of people into his office to give "statements" including one girl who works for me and is very intimidated by both of these managers.
They had a bunch of meetings and have determined that I have filed some kind of official complaint and are now gathering their defense! It's so stupidly funny.
NO one involved - either the jerk or any of the managers or engineers on the client side - have said one word to me. Nothing.
I talked to my own bosses and they are going to pursue this down official channels because I'm not the only one treated this way by this guy. And, since his allegations are entirely false - and I have the paper trail to prove it - there will be repurcussions to him. I have the full support of my company - in writing. Its sad that it has come down to this, but he began it.
The down side is that its taking my company so freaking long to do everything 'officially' and tomorrow is the weekly project meeting where I am the only representative of my company and the others are all on the client side - including the jerk.
I have my approach tho. I'm not going to say anything regarding that. I'm sticking to the project and the meeting agenda and *if* anything is said to me my reply will be "under advice of my attorney I can't talk about it" and that should shake them up!

LOL!
