Hi Shy,
I accept your things. I faced such a problem a lot in my previous company (It is a very big story). You know, if the seniors can't do anything, they will fire the juniors.
In my point of view, you should do your work first. I mean try to learn about HR, how people are behaving with others, closely watch them, because this is a very good chance for you. You won't get those kinds of people in your life hereafter.
So, be cool and have a focused day!
Thanks,
Rajan
