Vantaggi
The benefits are the best reason to work at Boeing. My health care package and 401K are better than the majority of my friends working at other companies. Also, if you want to to get a master degree or just take random classes, Boeing pays for all of it. It is one of the best continued education programs out there. Also, when times are good, it is pretty easy to move around and get a variety of experiences. Flex-time (9-80s and 4-10s) is an additional benefit that is quite nice.
Svantaggi
The work statement for new employees often is not very interesting. Also, it seems like management is more concerned with the years of service rather than accomplishments of an employee when considering people for promotions. I have had numerous friends leave the company for one or both of those reasons. I am not a big fan of the vacation policy. You initially receive 2 weeks per year plus 2 weeks of sick leave. If you are like me and rarely get sick, watching all of the sick leave go unused while constantly running low on vacation is quite frustrating. In the end, I think Boeing is a great company for the right type of person. If you are into having small focused work statements, without much variety, this would be a great company to work for.
