Pros
Good benefits. It's a job. Rare layoffs.
Cons
Depending upon where you are, you may get a supervisor and/or manager who has been there a very long time, and because of close ties to owners, they'll never leave, despite incompetency. You need to simply put up with the insanity. Also, some employees are highly competitive, even if that means leaving you in the dark about needed information or grabbing credit for work you've done. Advice: Don't go to the on-site medical department if you value your privacy. Also know that everything you say will be later documented in your medical record, regardless of what it is or whether or not it has anything to do with anything. If they misunderstood something, they will argue with you rather than change the record. Someone said elsewhere in reviews, "No one ever leaves." Believe me, they do.
