A federal appeals court on September 2, 2026 rejected the NLRB's 2022 Tesla framework for judging dress code and uniform policies, a decision that hands employers in the Second Circuit a stronger defense against unfair labor practice challenges to appearance rules.

In Siren Retail Corporation, d/b/a Starbucks Reserve Roastery v. NLRB, the U.S. Court of Appeals for the Second Circuit overturned the Board's finding against Starbucks' one-pin rule and sent the rest of the case back for reconsideration under a balancing test. The ruling touches a concrete people-process question: whether uniform and dress code policies restricting union buttons, insignia or message clothing are presumptively unlawful — or judged case by case.

What does the ruling change?

The Board's 2022 Tesla decision created a legal presumption that employer uniform and dress code policies restricting employees' display of union insignia or messages are unlawful. To rebut it, employers had to prove "special circumstances" justifying the restriction and show the restriction was narrowly tailored to those circumstances.

The Second Circuit refused to apply that framework. It held that the Supreme Court's Republic Aviation decision does not make every restriction on union insignia unlawful, but instead requires balancing employee rights against employers' legitimate business interests. In the court's view, Tesla improperly tipped that balance by imposing an overly demanding standard on employers whenever a dress code limited union insignia display. The court faulted Tesla for giving insufficient weight to employer interests such as brand image, uniformity and workplace operations, and for failing to distinguish minor from substantial restrictions on employee expression.

What happened at the Starbucks Roastery?

The case arose during a campaign for a first collective bargaining agreement at a flagship Starbucks Reserve Roastery in New York City. A group of employees arrived in t-shirts bearing their union's name and logo. The shirts violated Starbucks' dress code, and the employees changed into their uniforms when asked.

The union filed an unfair labor practice charge targeting three dress code rules:

• a rule limiting employees to one non-Starbucks approved pin;
• a rule prohibiting pins advocating political, religious or personal issues;
• a rule restricting shirts with unapproved logos, designs or writing.

The NLRB found all three rules unlawful. The Second Circuit overturned the finding on the one-pin policy, citing a prior Second Circuit decision that had already upheld a materially similar restriction, and rejected the Board's Tesla-based analysis of the other two.

The court did not expressly declare Starbucks' policies lawful. It returned the case to the Board for reconsideration under a balancing framework. Relevant factors include whether restrictions are complete or only partial, whether they are facially neutral, nondiscriminatory and applied consistently, and the overall context behind the restriction.

Why does Loper Bright matter here?

A substantial portion of the opinion addressed a question now recurring across labor cases: how much deference courts owe the Board's legal conclusions after the Supreme Court's 2024 Loper Bright decision eliminated Chevron deference to agency interpretations.

The Second Circuit drew a sharp line between facts and law. Courts will continue to defer to NLRB factual findings supported by substantial evidence. But they must now independently evaluate the Board's legal interpretations — which may be persuasive, but no longer command Chevron-type deference.

For employers, that opens new avenues to challenge Board-created legal standards in federal court. It also signals that courts may revisit longstanding NLRB doctrines resting on debatable readings of Supreme Court precedent.

What should HR teams do?

The ruling adds to a growing line of federal decisions rejecting or limiting recent NLRB doctrinal changes, and it reinforces the post-Loper Bright trend of closer judicial scrutiny of the Board's legal reasoning.

The decision supports maintaining facially neutral dress code and uniform policies that serve legitimate business interests, particularly where policies impose only limited restrictions on employee expression. It does not eliminate the need for caution: employers should still assess whether appearance policies could affect protected concerted activity and ensure those policies are applied consistently across the workforce. As the Board reworks its doctrine under the Second Circuit's balancing test, more circuits are likely to weigh in on whether Tesla survives elsewhere.
