Funny thing was when we were both supervisors
I didn't know that he was stabing me in the back to make himself look good
I didn't know about this until a long time after he was made manager
When he was manager I spent three years putting out fires that he created
After our blowup I knew that I was transferred into HR so that the VP could work up a case to get rid of me

The funny thing was over the next year his department went to heck and had their worst production year in memory
I however was promoted after that year
