Pros
Boeing is a very stable environment at the site I work at. It is a generally laid back atmosphere with strong compensation. Most of it's benefits are competitive with peer companies and generally it would take a lot to get fired or laid off.
Cons
Unfortunately that stability also seeps into a seeming inability to make cuts based upon performance. It reminds me of office space where you only need to do just enough to not get fired. As long as you don't care how long it takes to move up this is a great environment. Forget what people might have told you about Boeing having great fringe benefits such as education reimbursement. Benefits have been on the decline lately. The business is facing some headwinds which results in our "Industry Leading" benefits now becoming merely "competitive." And by competitive they mean average.
