Excellent employer until your individuality clashes with someone's pride and ego.
Pros
Knowing that you are part of an organization that is REALLY the best place for a sick child to go. They have the very best doctors and services for all children, even the homeless who cannot pay a penny for their visits, specialists, medicine or surgery. If I had a sick child, he would go to Cook Children's. I worked there for four years. They get 5 stars for the services they provide.
Cons
The culture of the hospital, and therefore also of the contractors, is one of a strict hierarchy that allows for NO variation in procedure, or in the comfort level of over-sensitive, self-important individuals that are myopically entrenched in their singular duties. It's a secretive and back stabbing environment that compliments you for an action on behalf of a child on the one hand, and then undermines your status as an employee for doing the same action with a Cook receptionist or case worker who cannot stand to be questioned about anything. They are so insecure and mentally fragile that it shakes up their nested position. So they lash out by reporting offenders to the highest management possible in order to get revenge. That way, every manager from the top down "knows" what you did. My manager was VERY supportive and understanding of our higher manager's idiosyncrasies and paranoia, until he fired me in order to stay in good standing with his superiors. They get 1 star for instilling fear into the employees in order to keep them kissing up.
