Insecure High D Feeling Left out
I have a direct report who is both a high D and very insecure. Especially when he perceives that he is being left out of a conversation or project o rproblem resolution that he perceives as impacting him etc. I have tried to look at it from all perspectives but feel that this comes down to a pure control issue. To boot this individual comes across to both myself (his manager) and his peers as abrupt and bossy especially when he's scolding others for leaving him out of a conversation or project. This has been the case since he started working for me and has not improved even after several feedback attempts after which he still sees it as frustrating that he is somehow excluded from communications. I even go out of my way to forward emails or fill him in on a conversation that I had with another individual to keep him in the loop. However instead of his response being "thanks for letting me know" it's " I don't understand why you didn't just copy me on the email". Many times the communications are between me and another manager or above, which I have also explained to him, but this has had no impact. At the end of the day I feel that this person's reaction is petty and highly immature and his reaction \ behavior of scolding me rather than thanking me for letting him know is really getting old if not obnoxious and insubordinate.
Is it my feedback that's the problem or is this just a lost cause, or am I just overreacting to it?
