Pros
Medical Benefits are excellent and a great place to work if you want to have kids because you can get 6 months of leave.
Cons
You can expect long hours with little reward for the extra effort in PD. You might get a lot of additional responsibility but don't expect additional pay. Management (Director and up) will know they have an issue driven by market conditions, but allow the sales force to be punished financially for the issue and also continue delivering the same criticism of performance, without taking any accountability for their own lack of action. Poor communication, poor operational execution by CPS, lack of leadership at the highest levels of the business unit, etc. People are not rewarded with promotions, in fact people leave and experience far better career growth.
