+ Slow Pace: Boeing, along with the rest of the airline industry, is obsessed with safety. As a result, the pace of innovation is very slow. Few people in the company get to really push boundaries and make a dent in the universe. Those that do have to stay with the company for years - it takes a long time to make/change an aircraft design.
+ Lazy Culture: Because of the obscenely high amount of job security, good compensation, and slow pace, the large portion of the population is complacent. Those who want to change the world and make a difference leave, leaving a bunch of B level performers. New "As" either turn back around and leave, or they themselves become complacent, having no reason to try hard. Even the best aerospace engineers typically leave and come back as a consultant, getting paid even more than what Boeing already offers the engineering union.
+ Ageism: There's a huge age gap in the company in all areas. This often manifests itself in impatient "kids" wanting to do something new, but are actively discouraged or ignored by the "old timers" who think they know the right way to do everything. Promotions are only partially merit based, and much of it requires a certain number of years at a certain level as per the "process". There are many 1st level managers who go their position solely because they've been at the company for decades with no excuse to let them go.
Overall, I recommend Boeing for those who prioritize a stable job and good work life balance over anything else - it's a good family job. Also, engineers (those that can get a SPEEA union job) should go into Boeing. No brainer. The compensation and job security are stupidly high for SPEEA.
For those ambitious with their career, look elsewhere, because Boeing will make you dumb and lazy if you're not careful.
