Cons
Employee morale is extremely low. Compensation and high employee turnover makes it hard to remain an employee there. Many employees as well as managers do not have business or finance degrees and lack the crucial management skills to adequately address employee morale and respect. It is an issue that never seems to go away. Compensation comparable to other jobs at similar companies is extremely low and yearly bonuses might as well be none at all. For a billion dollar company, they do not treat their employees with the respect they deserve.
