Schultz, who stepped into the CEO role for the third time in April, has been trying to stave off growing unionization efforts. As of June 24, over 130 stores with more than 3,400 employees have had their unions certified by the National Labor Relations Board, or NLRB. The board has certified decisions against unionization at 15 locations through that date. And dozens of other stores are holding elections.

Union organizers have in the past pointed to store closures as a way to intimidate workers.

in June, Starbucks (SBUX) workers at an Ithaca, New York, store claimed their location was being shut down in retaliation for their union activism. The worker committee said at the time that it was filing an Unfair Labor Practice charge with the NLRB, alleging that Starbucks was making a "clear attempt to scare workers across the country."
