Hours, Office Politics
With high pay comes hard work. No complaints about that because everyone is expected to work hard in return for h high salary. Some departments, however, are more flexible than others when it comes to working from home. After a 40-50 hour work week on a Thursday or returning from travel, it would be nice to just relax and work from home. In the departments that allow this, you see lots more productivity, in the ones that do not, you see people wasting extra hours trying to get something done before they go home.
You can't get away from office politics anywhere you go so just match your personality with your manager's and you will get ahead - regardless of your performance or qualifications.
