Pros: good benefits
Cons: they don't appreciate the good people they had.
I spent 21 years working for SAE International. Gave my lifes blood, traveled all over and only got paid for the time I spent in meetings and was treated like a pariah when they downsized and laid over 80 personnel off in 2002. They refused to provide recommendations so that people could get new jobs. The use people up and the only people who benefit are the management staff.
