Pros
They had long term contracts and cant hire H-1B visas, they needed US citizens with clearance so didn't have to worry about competing with really low wages and long hours, and bad conditions. They had a company retirement but stopped it for new employees in 2006 but if you were there prior you still get it. Starting salaries are good but only for a few years when your not earning that much.
Cons
layoffs every year so you don't ask for raises or promotions, just lucky to keep your job. 40 billion pension deficit even though they stopped pension so they want most people with the pension to leave or they lay them off. Don't give raises and when they do they are nothing, have to ask senior engineers and IPTs to write a good letter of input to reviews so people just avoid you so they don't have to. Very petty and childish behavior competing to see who gets the raise and who doesn't, its every man for himself not teamwork. Manager assigns what you work on and then says you don't get a raise because of what project you were on when hes the one assigning the project.
