Apple’s Steve Jobs directly asked former Google Chief Executive Eric Schmidt to stop trying to recruit an Apple engineer, a transgression that threatened one junior Google employee’s job, according to a court filing.The 2007 email from Jobs to Schmidt was disclosed on Friday in the course of civil litigation against Apple Inc, Google Inc and five other technology companies. The proposed class action, brought by five software engineers, accuses the companies of conspiring to keep employee compensation low by eliminating competition for skilled labor.

Who said Apple and Google couldn’t be cooperative?
