Pros
Worked happily at The Dominion of Canada for 7 years, in two departments under five managers. It was close to home and my first "real" job after university. I made several life long friends during my tenure there. Some managers were excellent.
Cons
When a new manager was assigned to my unit the morale of the entire team went down hill. This person was known to be terse, abrasive and have unreasonable expectations. I'm not sure how he was promoted to a manager within the company, as all of the other managers had excellent people skills and knew how to motivate people and bring out the best in their staff. The "new" manager had people in tears that I'd never seen cry in 7 years.
