A few months ago I hired an overqualified for position my team. He's had some interpersonal communication problems (behaviors = assuming other person is incompetent, inappropriate exasperated body language, unwillingness to work within a team). I've provided feedback, but he's been fairly dismissive.
While I was in other meetings, issues came up. I received feedback from two people on my team, another manager we work with, and a very senior manager in the firm that he was very unpleasant to work with (there was a lot more).
He also suggested to another I knowingly allowed an error to go uncorrected, and that my leadership was questionable at best.
Any advice for how to handle this? Today I just took a breath and went for a walk.
