Apple CEO Steve Jobs will take a leave of absence from the company for medical reasons, but will remain involved in major strategic decisions, the company said Monday. He will leave day-to-day operations to COO Tim Cook.

Jobs made the announcement in an e-mail message to Apple employees, the company said.

This is the second leave of absence Jobs has taken.

Apple provided a copy of the message, which read:

Team,

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.

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.

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.

Steve
