Imagine your boss or another department manager asks you something. You start formulating the idea in your head... and before you can speak Mr. Know-It-All barges into the conversation and tries to help and answer.
Now you are promoted to be the boss and manage your team including Mr. Know-It-All
You need some help from your team. Or you want to inspire some teamwork and brainstorm ideas from everyone. Mr. Know-It-All is more than ready to help - as long as he moderates the show, or is the only one who speaks.
Moreover, it seems like everyone is used to his proactive interventions and thus all are reluctant to speak out first because Mr. Know-It-All always has to say something anyway. Or, whatever is said needs to be approved or criticised by Mr. Know-It-All. He has the final word.
As a new manager, I am confused about how I should behave with a person like this.
Personally, I feel a bit irritated that he tries to take matters into his own hands - it feels as if he undermines my and others' ability to follow the procedure I started.
Over time I have grown so reluctant to speak to the team as a whole that I prefer talking to everyone individually - because that seems the only way for me to communicate freely with everyone, without this guy barging in.
I am not sure whether my behavior is correct, nor whether I should be too concerned about him. Am I wrong to be irritated? Should I give him more of the limelight and try to recognize his insights as valuable so he can be groomed as my "successor"?
Or should I privately tell him something like "You know a lot and that's good. You just need to give others a chance to speak and come up with their own ideas. Also if you have any criticism, tell the person in private rather than in front of everyone!"
How can I deal constructively with this type of person?
