The U.S. Court of Appeals for the Second Circuit has issued a ruling that makes it easier for employers to defend uniform and dress code policies against unfair labour practice challenges.
The decision, handed down on September 2, 2026, arose from a case involving Starbucks and its flagship Reserve Roastery location in New York City.
The case centred on the National Labour Relations Board’s 2022 Tesla decision, which created a legal presumption that uniform and dress code policies restricting union insignia or messages are unlawful.
Under the Tesla framework, employers faced a significant legal burden, required to demonstrate not only “special circumstances” justifying any restriction, but also that the restriction was narrowly tailored to address those specific circumstances.
The dispute at the New York Starbucks Reserve Roastery began during a campaign to secure a first collective bargaining agreement, when a group of employees arrived wearing t-shirts bearing their union’s name and logo.
Because the t-shirts did not comply with Starbucks’ dress code, the employees were asked to change into their uniforms, which they did without further incident.
The union subsequently filed an unfair labour practice charge alleging that three rules within Starbucks’ dress code policy interfered with employees’ rights under the National Labour Relations Act.
Those rules included a policy limiting employees to one non-Starbucks appearance item, commonly referred to as the “one-pin policy,” alongside additional uniform and dress code restrictions.
The NLRB found all three rules unlawful, but the Second Circuit overturned the Board’s finding on the one-pin policy, holding that a prior Second Circuit decision had already upheld a materially similar restriction.
The court went further, rejecting the Board’s broader application of the Tesla framework when evaluating the remaining disputed policies from the Starbucks dress code.
The court reasoned that the Supreme Court’s decision in Republic Aviation did not render every restriction on the display of union insignia unlawful, but instead requires a balancing of employees’ rights against an employer’s legitimate business interests.
In the court’s view, the Tesla framework improperly disrupted that balance by requiring employers to satisfy an overly demanding standard whenever a dress code or uniform policy limited the display of union insignia.
The ruling is significant for employers across the Second Circuit, which covers New York, Connecticut, and Vermont, as it reduces the legal presumption of unlawfulness attached to standard workplace dress codes.
Labour relations practitioners and employment attorneys are closely watching whether the decision prompts the NLRB to revisit or modify the Tesla framework in response to the court’s rebuke.
