My manager is an interrupter. In every conversation, every meeting, and every interaction she speaks over the other people in the room. On days when she's in a good mood, this takes the form of her words simply flowing right over the others in the conversation. In circumstances when she's not in a good mood, she uses words and volume to verbally steamroll the other voices -- opposing or not.
In a meeting with my directs last week, in which I was giving instructions to my people, she usurped the conversation by brute force and began giving her own -- conflicting -- instructions. I approached her privately and explained that the conflicting instructions were confusing to the group and said I needed to proceed with the project in the order in which I had planned.
What ensued was a verbal dressing-down, the likes of which I have never experienced. Besides the content of her tirade, which was somewhat off-the-wall for a good manager, but not relevant to this particular post, she raised her volume and spoke over me each time I began to respond to her comments. At one point, I asked her to please let me finish and I was told sharply, "No, I'm speaking here."
What tack should I take with the chronic interrupting? Professionally, I feel my manager is not hearing me at all. I feel powerless and controlled. Personally, her behavior is becoming intensely frustrating and I dread speaking with her. And how do I handle the critical fact that my directs are getting unreliable information from my boss?
