Starbucks shareholders seek input on labor rights review

NEW YORK, June 8 (Reuters) - Starbucks should select an unbiased law firm and cast a wide net as the global coffee chain begins to assess whether it respects baristas' right to unionize, four shareholders said in a letter on Thursday.

The shareholders, including Trillium Asset Management and New York City's public pension funds, said they met Starbucks CEO Laxman Narasimhan last month to discuss the review, according to the letter sent to the company on Thursday and seen by Reuters. (Reporting by Hilary Russ)
