Pros
Stability and opportunities for advancement. GD is a rock solid company that isn't going anywhere any time soon, even in this unstable market and the uncertainty of this new administration. They continue to win contracts every day. They also offer a comprehensive benefits package that is as good as it gets out there. The management does communicate with employees a lot more than other companies do, and you don't feel so alone when working for the customer.
Cons
GD has a reputation of paying on the lower end of the acceptable range. They target enlisted military separating the military because they know that they can get away with paying less, especially for many of the positions that they need to fill. There is a history of not rewarding the employees, but that isn't an organizational-wide problem, only in different areas. That is normal though. The good side is that changes have been made and are starting to be seen at lower levels.
