AYESHA RASCOE, HOST: Tomorrow, there'll be a homecoming of sorts at Starbucks. Howard Schultz is coming back as interim CEO. Schultz built the company into a global powerhouse. He's also responsible for Starbucks' reputation as a great place to work. Now high on his to-do list - to save that reputation as workers band together to raise grievances and demand more. NPR's Andrea Hsu reports. ANDREA HSU, BYLINE: Last November, Howard Schultz traveled to Buffalo, N.Y., to try to cool a grassroots union campaign. Store employees were invited to spend part of their Saturday with him. (APPLAUSE) HSU: Schulz donned a Mister Rogers look with a zippered cardigan for what he called an intimate conversation. (SOUNDBITE OF ARCHIVED RECORDING) HOWARD SCHULTZ: I just want to speak from my heart about what I believe this company is about and what we've tried to do over these many years in building a different kind of company.
