I am having a problem with one of my coworkers that seems to be getting worse. We are both Senior Engineers of equal position on the same team, working for a large multinational Engineering company.
My colleague has a reputation for being somewhat brash and has a tendency to dominate conversations. He has a habit, especially if we are on a conference call together, of cutting me off when I am speaking. Frequently, I will start speaking and he has a tendency to just start talking over me and completely ignore what I am saying.
Needless to say, I find this behavior extremely rude and disrespectful. It is getting to the point where, when he does it, I get very triggered and have started reacting negatively, lashing out verbally. For example, he did it on a call earlier this morning; I said several times, patiently, "excuse me, I am talking. Can you please wait until I am finished?", yet he completely ignored me and continued to talk. I lost my temper, gave him a couple of choice words and promptly dropped off the call.
I am not prepared to tolerate him showing me such blatant disrespect, when we are both Engineers of the same level and especially when we are on a call with other people. I am afraid that if it keeps happening, my outbursts will get worse and I will run the risk of gaining a reputation myself of being 'unstable' or 'temperamental'. This doesn't happen with anyone else in our business, except him.
The situation may be party caused or exacerbated by the fact that I have a minor stutter when I talk and don't have the same level of spoken confidence that he does. So, it seems he feels he can easily 'knock me aside' in a discussion, whenever he feels like it. Again, I am not prepared to tolerate this. I am also a respectful and dignified person myself, and I will not talk over someone else or fight just to be heard.
So, my question is: what is the best thing to do in this situation? Has anyone else experienced anything similar? I am guessing that speaking to my Manager is probably going to be one of the first suggestions. I have done that and he is aware of the problem, but I'm not sure if he knows what he can do to help. I have made it clear that I will not tolerate his behavior and if I feel triggered then I will drop off calls, as necessary.
I would be very grateful for any advice.
