I recently joined a company as a network engineer. Almost all the people here are personally known to me.
One guy who works here, who used to be my good friend out of office, is not keeping up with the team properly.
The company wants to fire him and he is searching for another job. The people who want to get rid of him are also close friends of mine.
So because this guy has no "friends" in office he always hangs out with me. Probably other guys in the company don't like this. I don't find this person trustworthy, but used to be a casual "friend" out of office.
I'm not quite sure if I should avoid this person just like seniors do. Being neutral might be good. How to handle this scenario?
