Apple CEO Steve Jobs told staff at the company today that he was taking a "medical leave of absence".
He did not reveal specifics about why he had been given time off from the Mac and iPhone maker.
"At my request, the board of directors has granted me a medical leave of absence so I can focus on my health. I will continue as CEO and be involved in major strategic decisions for the company," he told employees in an email.
"I have asked Tim Cook to be responsible for all of Apple’s day to day operations. I have great confidence that Tim and the rest of the executive management team will do a terrific job executing the exciting plans we have in place for 2011."
Earlier this month Apple advised its shareholders to vote against a proposal to reveal a “succession-planning policy” for the company’s CEO.
"I love Apple so much and hope to be back as soon as I can. In the meantime, my family and I would deeply appreciate respect for our privacy," said Jobs.
The Apple boss returned from medical leave in June 2009 after receiving a life-saving liver transplant. ®
