Bad Mood!

I love my job, although it looks simple & boring. This job given me lot of personal time & learning apportunities. But it has turn bad recently. New colleagues make my working life difficult now, they are very bossy & pride & not willing to learn. The worst is......I have to cover their mistakes. The saddest is they will complain to boss that I did mistakes but actually that was their mistakes. They were previously from big company & always feel they are big also. They spoiled my daily mood for their irresponsible!! They are men......they are the worst lousy men that I ever met!!
