I've been hired as a manager for a small, existing team. I have gotten feedback about one individual's past behaviour which I personally have not seen over the past 6 months I have been with the team. In fact, the individual seems to be demonstrating very positive behavior in front of me. In addition, the same perosn gives me feedback about the person again, but it is stuff that I have not seen or cannot verify because it has happen between them when I am not around.
It could be that the person giving feedback just doesn't get along with the other person and may be using some kind of filter when dealing with the other person. On the other hand, the person giving the feedback has been with the company for 7 years and has given me balanced advice so I would doublt if there is some kind of personal agenda.
What to do about this? Do I share this to the other individual?
