The Second Circuit Court of Appeals ruled on September 2, 2026, in the case of Siren Retail Corp. v. NLRB (Docket No. 24-3168), favoring Starbucks in a dispute regarding its employee dress code policies. The ruling affects how companies can enforce dress codes, particularly in relation to employee rights to display union insignia. This decision is significant as it clarifies the balance between employer policies and employee rights under labor laws.

The case began when employees at the Starbucks Reserve Roastery in New York City wore shirts supporting their union, Starbucks Workers United, during a campaign to negotiate their first contract. After Starbucks requested that these employees change into dress-code compliant shirts, the union filed an unfair labor practice charge against the company, claiming violations of the National Labor Relations Act (NLRA). The National Labor Relations Board (NLRB) initiated proceedings against Starbucks, alleging that its dress code policies restricted employees’ rights to engage in union activities.

The dispute centered on three specific dress code policies: the One-Pin Policy, which allowed employees to wear only one union button; the Issue-Pin Policy, which prohibited any buttons advocating political, religious, or personal issues; and the Logo-Shirt Policy, which restricted shirts to those pre-approved by Starbucks. An Administrative Law Judge (ALJ) initially sided with Starbucks on the One-Pin Policy but found that the other policies violated the NLRA.

Starbucks challenged the NLRB's findings, particularly the Board's application of a new standard known as the Tesla test, which presumes that all employer dress codes that limit union insignia are unlawful unless narrowly tailored to serve special circumstances. The NLRB had ruled that Starbucks' dress code was not sufficiently tailored to justify its restrictions on employee expression.

In its ruling, the Second Circuit Court of Appeals granted Starbucks' petition for review and denied enforcement of the NLRB's decision regarding the dress code policies. The court stated, "The Board’s Tesla test, as applied by the Board, fails to properly balance employer and employee interests." The judges emphasized that the One-Pin Policy was consistent with a previous ruling in Starbucks I, which had determined that similar policies did not violate the NLRA.

The court found that while the NLRB had a valid point regarding the need for a balance between employee rights and employer interests, the Tesla test was too rigid and did not allow for sufficient consideration of the employer's justifications. The court remanded the case back to the NLRB for further analysis of the Issue-Pin and Logo-Shirt Policies under a more balanced test.

This ruling has significant implications for labor relations, particularly for how companies can implement dress codes without infringing on employees' rights to express union support. It sets a precedent that could influence future cases involving employer policies and employee rights under the NLRA.

Looking ahead, the NLRB can still appeal this ruling, and it may also consider related cases involving similar issues of employee rights and employer dress codes. The outcome of this case could shape the landscape of labor relations in the retail industry and beyond, as companies navigate the complexities of maintaining a professional image while respecting their employees' rights.
