I heard a story,

one of my friend was fired by the company, but when he signed contract with company, indicating if he is being fired, company need to pay him XXX money to him, but that day when he was fired, his big boss called him, "get your attonery, I am not going to pay you a penny. " From this case, I learned, 1. sometimes there is no rule/law in reality; 2. American will negotiate package including if being fired, we may need to learn on this....
