Apple's next CEO, John Turners, faces a major challenge as he assumes the role: retaining top talent during a period of historic personnel change. After several relatively calm years, Apple recently experienced a wave of departures, affecting both senior executives and junior engineers. Turners, who will succeed Tim Cook as CEO in September, is tasked with stabilizing the workforce. Late last year, the highly acclaimed chip chief, Johnny Sruggie, told Cook he was seriously considering leaving Apple. Apple recently retained Sruggie by offering him a new compensation package and a broader position—the company's first Chief Hardware Officer. Turners will need to address succession issues and the potential departures of other executives, including Mike Rockwell and several long-time leaders nearing retirement. (Jinshi)
