"office politics"

Yes, the reason I am now unemployed is because of office politics. I worked at this company before, and received a call from the boss that there was a position available. I accepted the position, which was actually the position of a friend that I have known for more than 20 years. She was being moved to a newly created position. Well, my friend trained me, and she was always in the bosses face. The boss started blaming me for errors in the work, which I did exactly like my friend had trained me on. My friend never took up for me, by saying well, that is the way I trained her. My friend was always in the bosses office, instead of at her desk doing her work. Well, it boiled down to, when the department decided to reorganize, the boss told me that my friend would resume her old position, and there was no vacancy for me, so I was laid off.
