Pros
Had a great initial leader and team environment. Good information flow and was encouraged to think beyond my current job or discipline. Very good benefits. Very good pay. Was able to learn a great deal about the company and industry and also allowed to take some risks and initiative, in my first two years.
Cons
Line of sight was cut off to other business units, and information slowed. The senior leaders of the company don't live the values. In every meeting with our most senior leader he never asked me how my work environment was and whether my leader was doing a good job. I would have said my work environment was toxic but my leader was doing best job possible - needed more support. Promotions are hard to come by and people slack off in their positions and let those below them do the real work.
