Hello friends, I work for a reputed company and i have two female colleagues (friends?). They are highly dominating and often throw satires on each other. Even if we speak something casually they search for a negative or inner meaning in that and start cracking vulgar jokes. This irritates me a lot and i just laugh artificially to their dirty jokes.I am generally soft-speaking and they take advantage of my calmness and start teasing me indirectly. I can't even understand that they r upto me. Really my situation is horrible between these two.Recently one more lady has joined in our department and thay have started criticising her.They complain to me about her in her absence.It is like this- They don't allow me to move with her and at the same time they keep stamping me. What to do with people like this ?
