Pros
Boeing offers a decent wage, good "traditional" benefits (medical, dental, vision), generous educational benefits, and potentially opportunities to move up/move around.
Cons
I've worked at a handful of companies before coming to Boeing and I have to say I've never encountered such terrible, terrible management in my life. Things you would think, especially in this day and age, would be considered an HR nightmare have been common place. I've had an opportunity to chat with a lot of fellow employees from different groups/programs/divisions and compare notes and I'll admit my experience is not "the norm," but it is sadly not as rare as one would hope. Ultimately, it's really a crap shoot as to what group you land in and what type of management you get when you're hired. Additionally, the company overall has a very "traditional" (translation, outdated) way of thinking which can be super frustrating and shows in their high rate of turnover rate of 0-5yr employees.
