I was fired for job abandonment. I finished my pin on the local sort and was asked to help out another pin. I was told by a supervisor, go help out with 2 cars then you can go. I did 3 cars then left. My boss calls 5 mins later and sayss I abandoned my job. I explained my situation, that i was told it was ok. I then said I was on my way back to the building to return, but my boss said nevermind ," you abandoned your job" we will talk tomarow. Will this stick? how can i be fired for this???
