I'm a salesperson that worked for a large telecommunications carrier. I had a written sales compensation agreement with them. My commissions were to be based upon my results vs. an established quota. During my employment I received an injury (not work related) that required extensive surgeries and that put me out on short term disability for almost a year. When I returned to work it was July. I was given a revised annual quota which was adjusted based upon the time remaining in the year. In Nov I was able to close a very large sale that put me well over my quota. AFTER I made the sale, my Sales Director doubled my quota, took half of my sale's revenue and spread it across the reps of another under performing sales team, and gave 25% of my sale's revenue to another salesperson on my team.
