More stores are anticipated to file for unionization and hold elections in the months to come. In response to its employees' organizing efforts, Starbucks has launched an intensive anti-union campaign to thwart the union effort, and on July 21, 2021, the National Labor Relations Board (NLRB) found that Starbucks unlawfully retaliated against two Philadelphia baristas in response to their unionization efforts and ordered the company to cease and desist from interfering with their workers' rights. Starbucks workers organizing in Boston have reportedly been subject to increased corporate pressure and surveillance, voicing shared experiences of upper management and corporate personnel, many whom baristas have never met, sitting in their cafes and observing baristas for several hours a day, while workers from two Greater Boston stores have additionally reported store surveillance technology upgrades soon after filing petitions to unionize.
