I used to know a chap who was a successful partner at a top UK law firm - he had a very successful run of work that lasted for years and made a lot of money for everyone. However, eventually he it came to an end and he had a less than successful month - he got the same bollocking about performance as everyone else, and in front of his entire team too.
the thing with sales is one you develop a sales skill and network - you go and set up your own shop and become an equity owner.
consider sales as a learning experience to set up your own shop
Some organisations are just run like that.
