Pros
Big company with big challenges which, if you're prepared to pay YOURSELF on the back for solving, is very rewarding. There's a sense of pride on working for Boeing which is not available on many other places - it may seem abstract but knowing that you're part of the 'family' which build the planes you get onto routinely is a very positive experience.
Cons
Most middle managers have been with the company for 20+ years and are completely out of touch with the workforce and the motivation strategies required. Boeing is trying very hard to recruit young graduates but is running the risk of a huge loss of experience by allowing those 20+ year tenure people to retire without capitalizing on the growing experience of it's middle tenure employees (who are really very restless and considering other work opportunities). The company need new blood, but as a large entity it cannot afford a knowledge drought while it establishes new working practices. I'm one of the new recruits but I'm horribly aware of the potential gap which could be created when a workforce as disenchanted as the middle tenure employees in this company leaves - they're the link between the strategic planning and ground-floor operations and their knowledge, although apparently not prized, is the backbone of the company.
