Prepare to give up your right to medical privacy.
Pros
Great commute and free parking. Good medical and dental benefits as well as solid 401K plan, etc.
Cons
You will have absolutely no opportunity to give feedback regarding the performance of management. If you are lucky to wind up with a good manager, yay for you! If you wind up with a crappy one (and there are a LOT of them) you are screwed. This is a company that cares little about th opinions of it's associates other than associate surveys that are so shamelessly slanted they guarantee a positive assessment. Also, your fellow employees will have access to your private healthcare information. For instance, that claim for your "rash" gets denied? You'll be chatting with your co-worker about it when you fight the denial. So much for HIPPA!
