Greenday,
People are not selfish but Nepali (not all, but most) are.....same thing happened with me but not by the one who is senior to me but from someone I hired and promoted , he start showing his face , color after I referred him to different department ,
he did everything to have me fired but these kind of people are so stupid that he never understand why my boss agreed to hire the person I refer... He tried to stabb me so many times but He never get succeed but it was really stress full to handle his Nepali type diplomacy at work ..
So I Totally understand what might going through him.
