Rossann Williams, who led Starbucks' largest market with over 18,000 stores for four years, is leaving the company, Starbucks said Friday.
Williams, a 17-year Starbucks veteran at the center of the company's response to a unionization push in the U.S. and Canada, will leave Tuesday. She was offered a different position in the company but declined, Starbucks said.
"We have made a difficult, but necessary change to our North America business," Starbucks said in a letter to employees, "a change that creates new leadership for a new era at Starbucks."
