Pros
The benefits at Boeing are generally better than other companies of comparable size. Paid overtime is rare to see at large companies like Boeing, and the retirement benefits are awesome. The 401k has a 75% match for the first 8% of your salary, and you can choose from about 20 different funds to put your money in. Also, there are not many US companies left that have a viable pension plan like Boeing does. Another amazing benefit is the 100% tuition reimbursement for essentially any class at any school for any type of education as long as it is somewhat related to your job function. Full medical, dental, and vision benefits are included as well.
Cons
They don't call Boeing the "Lazy B" for no reason. If you like a place where you can just get by and hang out at work without doing much "actual" work, Boeing is the place for you. Sure there are some employees that are great performers, but the majority of employees seem to be content with doing as little as possible. Promotions at Boeing are based exclusively on seniority, and not based on actual performance. This may be what accounts for the laziness as employees know that even if they overachieve, they will not be rewarded for it. The age of the company as a whole is also extremely old with approximately 67% of the company eligible for full retirement benefits within the next 5-10 years. Due to the aforementioned reasons, attrition is especially high for new hires as they struggle to come to grips with Boeing's aged and outdated corporate culture.
