Middle management has a clique where all started around the same time and are tightly bound to one another. It's not terrible but for those that want to climb, movement into management is indeed difficult to penetrate. It didn't bother me personally but I would equate it to a high school environment with these individuals who operate as an old boys' club, err womens' club. They spend a lot of time in each other's offices so yeah, like high school. One of the managers was a drama queen. Glad to be away from her histrionics. I believe she was later demoted so----good on that. Outside of this, the environment is great. Coworkers are terrific and overall the atmosphere is very positive.
