The National Labor Relations Board has filed a new complaint against Starbucks, accusing the coffee giant of illegally withholding wage raises and benefits from thousands of workers involved in union efforts. The complaint seeks full back pay for the workers and would require CEO Howard Schultz to record a video admitting his company’s illegal actions. Starbucks faces dozens of other unfair labor practice charges over its massive retaliation campaign against union organizers. Workers at more than 230 Starbucks stores have voted to join Starbucks Workers United since last December.
