Gucci CEO Mark Lee announced his resignation yesterday, leading to a big executive shuffle at Gucci Group. Bottega Veneta CEO Patrizio Di Marco will take Lee's spot, Stella McCartney CEO Marco Bizzarri will take Di Marco's spot, and it's unclear who will take Bizzarri's spot, leaving Stella McCartney one executive down. Lee called his resignation a “personal decision to rebalance my life.” Hey, who couldn't use a break now and then? His last day will be December 31. [DNR]
