Pros
Excellent pay. Benefits are outstanding (especially prescription drug coverage). Onsite cafeterias (with decent food). Several Fitness centers onsite. Twenty four hour security. Cutting technology in the labs. Safety is priority one.
Cons
Politics. It seems that folks who do the bulk of the work are never promoted, while the folks who simply compile data into charts move up the ladder. There is a feeling of lack of trust and respect. If a few hours is spent away from work for personal errands/doctor appointments, every minute is expected to be made up. That is fine. However if extra time is spent or if there is unscheduled weekend work (in order to meet deadlines, etc.) there is NO comp time. If you work extra hours, you're working for free.
