Why did he get fired?
He mentions that he has anger issues and drinks too much, but can that really be the reason? I mean, if they were so determined for him to remain silent, couldn't they just have given him another job at the same company? What pisses him off is that he gets fired.
And seriously, if they are using $600 million on lawyers a year, letting him keep his job shouldn't be a big deal.
So, what did he do, that made it so important to fire him?
