Michelle Gass, who had long been considered a possible replacement for Starbucks' CEO Howard Schultz, and who spent the past two years working on a turnaround for Starbucks’ troubled Europe, Middle East and Africa region is going to Menomonee Falls, Wis.-based Kohl’s. The retailer Wednesday said it has hired Gass in the newly created position of chief customer officer. She will oversee marketing, e-commerce and something Kohl’s calls “the customer’s total omnichannel experience."
