I rejoined a team recently that I was part of a few years ago. At that time I was friendly with and worked closely with a certain colleague.
For some reason now he doesn't even register me in the room, sits elsewhere during breaks and doesn't speak to me or include me in anything unless its absolutely necessary.
I just don't know why he is doing this...is he afraid of the competition? Does he dislike me? It's as if he wants me out of the team. It's not that we don't know each other very well...we do!
