The ruling by [National Labor Relations Board] Judge Robert A. Ringler found that the company and local store managers in Pittsburgh abused their power and unlawfully targeted workers organizing with Pittsburgh Starbucks Workers United.

Three of the fired workers were part of the union’s 5-member bargaining unit, a fact that Ringler suggested was not a coincidence.

As workers at Starbucks stores nationwide have racked up organizing victories, the company has been hit numerous times with NLRB rulings that found unlawful labor practices.
