I joined my current workplace 6 months back and I am a fresher (no previous work experience). My team initially consisted of just me (a girl) and another guy (who has 8 years work experience).
I thought we get along well. He expects me to include him in any work I do, but he excludes me out of his work. He becomes all defensive and secretive when I casually ask things.
I work day-in, day-out with R and have a substantial knowledge of statistics. Recently, 3 new members (all guys) joined our team and he is taking charge of "training" them on R and statistics, when he has very little knowledge. Now, they have meetings on R & Statistics and I am not even told. They conduct these "brainstorming" sessions almost everyday and I feel bad and excluded. I am all the more willing to help them out, but when they have meetings in a separate room, and they all act all high-and-mighty about it, I feel "Ok, fine. Let them do it their own way."
Should I be worried that this might lead to worse situations?
