I work in a small team of 5 members where all the other members except me are with the company since the very beginning (around 20 years). I have been here for the last 2 years.
Every once in a while, one senior developer will come to my desk and start gossiping about the manager. He does it when manager is not around. I don't want to listen to him but am afraid to say anything to him.
How can I tell him politely that I don't want to listen to it because it is not productive?
