About 5 years ago I was running a sales meeting with my sales team, there were about 40 people at this meeting from the field & corporate. We had a fairly new Marketing Director who was a in way over his head & everyone knew it. He made a lot of commitments & promises that never panned out. During his presentation my guys were grilling him & he had no answers. During the presentation following him, one of my sales guys made a remark about one of the Marketing Product Managers, & while I am standing in the back of the room, the Marketing Director grabs me by the arm & says "come with me". We leave the room, & he goes berserk out in the hallway & proceeds to push me against the wall repeatedly while he is shaking his finger in my face & yelling at me because he is mad that my guys are going after him & his people. Keep in mind that this guy is about 5'5" & 250 LBS, & I am 6' & 225. I remained cool as a cucumber & told him that this would end bad for him if he continued. I almost started laughing at one point. I knew that this clown was writing his ticket out.
I called HR & the next day I had to drive from St. Louis to Milwaukee for a meeting at Corporate. I got drilled by HR & corporate management for a couple of hours. Luckily the other guy admitted that he had lost it & was not provoked. He had over 30 years with the company & was terminated immediately. A few Months later he sent me a letter of apology.
