U.S. District Judge Lucy Koh's ruling on a plea for a class-action lawsuit against leading Silicon Valley companies includes high-tech leaders' emails revealing their agreements to not lure away each others' employees to avoid, she said, "bidding wars that could drive up wages" for all employees. She cited, among others: A 2005 email from Bill Campbell, chairman of the board at Intuit, to Apple CEO Steve Jobs, stating that Google CEO Eric Schmidt "firmly stopped all efforts to recruit anyone from Apple." A 2007 email from Schmidt to Intel CEO Paul Otellini, stating that "Intel has been on the Do Not Call list since the policy was created." A 2005 email between Bruce Chizen, then CEO of Adobe, and Jobs agreeing not to solicit any employee from either company. A 2007 email in which Schmidt confirms with Otellini that Google "do[es] not actively recruit from Intel ... If we find that a recruiter called into Intel, we will terminate the recruiter."
