Pros
Work at home is an option. Some great people really do work there. I get a package for leaving. Made me happy.
Cons
No work life balance. It feels like a gang war between ESI and Medco employees. They protect the people who used to work with them at their previous company whether they are qualified or not. Project managers are more like analysts in some departments. Director wasted people's time with dumb assignments that added no value to the company. Why would project managers be listening to 50 calls a day? Where they do that at? Express Scripts. Client needs are not the priority. Members are suffering due to inept processes that people either don't know how to fix or too prideful to fix since it was supposed to be a perfect system. New system is so flawed and so inflexible, it's pathetic. Expect you to work a ridiculous amount of hours with not even a thank you.
