The unionization drive at three Starbucks locations in Buffalo, New York quickly inspired baristas at other locations across the country to organize their stores: around 150 Starbucks locations nationwide have now filed for National Labor Relations Board (NLRB) elections.

Laila Dalton was one such worker inspired by what she saw in Buffalo. Dalton, who is nineteen, has worked at Starbucks locations in Phoenix since she was sixteen years old. She and her coworkers began organizing a union shortly after the Buffalo campaign went public. The day before they planned to announce their union drive, Dalton was called into a conversation with management, which she recorded. The video shows a supervisor listing a host of supposed violations on Dalton’s part, yet she and her coworkers attest that she had never previously had any infractions and is known to work overtime to keep the store afloat as a shift supervisor.

The workers believe the incident, along with one against her coworker Alyssa Sanchez, was retaliation for legally protected concerted activity, so they filed an unfair labor practice (ULP) charge against Starbucks over its actions. On March 15, the NLRB issued a complaint against Starbucks for retaliation. The Board has previously charged Starbucks with retaliation against workers in Philadelphia, but this is the first such complaint in the current Starbucks campaign. The regional office can now prosecute the case, and the company will have the opportunity to appeal its decision to the full NLRB in Washington DC.
