Pros
Boeing is a fairly steady company (current 737 issues aside) and they provide a lot of jobs, with decent pay and decent benefits. In my experience, those jobs are good for a large portion of people who just want to come in and punch a clock, individuals who seek to conform and do things the Boeing way, and perhaps for people who have high aspirations that just want to climb the ladder quickly. There are some pockets of truly dedicated and conscientious leaders there. The company is useful in seeing how long standing major corporations operate and function.
Kontras
However, in my experience, wanting to feel my work was meaningful wasn't part of the deal, I was a cog in the machine and my opinion or experience didn't matter, It was all just about getting things done. This model likely accounts for the current problems with Boeing's production lines, they just want "yes people" who don't stir the pot or try to do things different way.
