I have a colleague who is not only very intrusive, but also makes constant jibes at me.
He keeps snooping what I am doing on my computer (even though I am just working) every time. But that's not even the issue.
He makes attacking statements every time, especially in a large gathering. Although he makes comments about trivial things, it affects me. For instance: I am a few years older than him. He makes fun of the fact that I am stuck in the same level as him. There are many other instances (too many to list here).
I am posting this here out of frustration because I don't know what to do. I avoid saying something to him since he is extremely sensitive. He will sit and sulk for the next one week if i said something in retort.
I think his bitterness stems from the fact that I am not very chirpy and friendly to him. But I am introvert, and that's how I am. Also, I do not particularly get along well with him either.
What can I do to make him stop?
