Everybody loves a fat pay rise. Yet pleasure at your own can vanish if you learn that a colleague has been given a bigger one.Indeed, if he has a reputation for slaking, you might even be outraged. Such behavior is regarded as "all too human", with the underlying assumption that other animals would not be capable of this finely developed sense of grievance. But a study by Sarah Brosman and Frans de Waal of Empir University in Atlanta, Georgia, which has just been published in Nature, suggests that it is all too monkey, as well.
