Perhaps your brother was really awesome at doing his job, and that was a calculated risk on the part of his company. Perhaps they did it to make an example of him and raise the morale of everyone else there. But if they just did it out of the kindness of their hearts, then they violated their fiduciary duty to maximize their shareholder's profits.
No one should ever mistake a company for anything but a profit seeking machine. They vary in their competence toward seeking this goal, and in the timeframes over which they expect returns, but that is what is at their core. Companies that don't behave this way just get eaten by those that do. It isn't even their choice.
