Pros
Working in the corporate office, teammates stick together and are very hard-working. Most mid-level managers are fair, understand how hard people work and try (mostly unsuccessfully) to provide career growth.
Cons
Senior management are former blue-collar trash collectors (literally) in the position of running a large company. If you deal with senior management you will hear some of the foulest language ever uttered in an executive boardroom. Extremely unprofessional communication and behavior. No qualms about publicly embarrassing employees/threatening to fire them in front of large groups of people. Unless you are being trained for the job, there is no career-oriented training. The longer you stay static in your career, and exhibit no ambition, the better off you are. Heaven help you if you make a suggestion or even try to make a suggestion to improve the company to senior management. People have been belittled and pushed out of the company as the CEO takes suggestions for improvement as a personal attack. Technology from 2003 - company IT infrastructure run like a 50-person mom-and-pop not like the multi-national company it is.
