Starbucks filed two complaints with the National Labor Relations Board on Wednesday alleging that the union organizing its baristas broke federal labor law.
This marks the coffee chain’s first time on the other side of accusations around lawbreaking behavior amid the union battle.
Workers United, an affiliate of the Service Employees International Union, has filed dozens of complaints of its own against Starbucks with the NLRB, alleging that the company has illegally retaliated against, harassed and fired organizers in cafes across the country.
The government agency has similarly filed two complaints against Starbucks alleging that in Phoenix it threatened employees and fired organizers in retaliation. Starbucks has denied all allegations of union busting.
More than 200 of the coffee chain’s locations have filed paperwork to unionize under Workers United since August. To date, 24 stores have voted to unionize, with only two locations so far voting against.
In the complaints filed with the NLRB, Starbucks alleges that Workers United “unlawfully restrained and coerced partners in the exercise of their rights,” citing incidents that occurred at two cafes in Denver and Phoenix.
Starbucks claims in the filings that organizers physically blocked the entrances and exits of those stores, made threats and physically intimidated baristas who didn’t support the union drive.
The complaint alleges that organizers also yelled profanity at customers and hit cars with a picket sign as they tried to enter and exit the Denver location. The complaint does not detail when that incident occurred, but workers at the Denver cafe named in the filing held a strike March 11 to protest what they called unfair working conditions.
Starbucks Workers United did not immediately respond to CNBC’s request for comment.
The Phoenix location mentioned in the filings is the same cafe that is at the center of the NLRB’s complaints against Starbucks.
“We’re doing this to protect the physical safety and emotional wellbeing of our partners and to make it very clear that the behavior we’re seeing from some union organizers is not acceptable and we won’t tolerate it,” Rossann Williams, president of Starbucks’ North American operations, wrote in a letter to employees viewed by CNBC.
“I want every partner to know we respect and honor all their rights — the right to choose a union, and the right to choose to speak for themselves,” Williams added.
