CEO Sam Palmisano is proud of how "responsible" IBM has been. But don't forget: A corporation's only true duty is to its shareholders. And that's reflected in IBM's 2007 Corporate Responsibility Report. There's no cost-savings measure that can't be spun as a do-good move. Like IBM's Healthy Livings initiative, which effectively punishes employees for being fat. In 2007, Palmisano proudly writes, that program was expanded to cover employees' fat children as well. Technically, thin employees and their brood get "rebates," but it adds up to the same thing: Big Blue makes you pay for being big. After the jump, the chest-thumping brag from Palmisano, who's not that small-boned himself.
