News Summary
A federal judge has issued a preliminary injunction against California’s Senate Bill 399, affirming employers’ First Amendment rights. The law sought to limit employer communications on religious and political issues, particularly regarding unionization. This ruling, welcomed by the National Federation of Independent Business, emphasizes the importance of free speech for employers and highlights ongoing tensions between state and federal labor laws. As litigation continues, stakeholders are urged to monitor its implications for workplace communication in California.
California – A federal judge has issued a preliminary injunction against California’s Senate Bill 399 (SB 399), temporarily blocking its enforcement and reaffirming employers’ First Amendment rights. U.S. District Judge Daniel Calabretta ruled that the law, which was passed in 2024 and took effect in 2025, is preempted under the National Labor Relations Act (NLRA).
SB 399 aimed to restrict employer communications regarding religious or political issues, specifically concerning mandatory attendance at meetings discussing topics such as unionization. The ruling indicates a significant affirmation of employers’ rights to free speech within their businesses.
The National Federation of Independent Business (NFIB) has welcomed the ruling, emphasizing its importance for small business owners’ free speech rights. The federal lawsuit challenging SB 399 was initiated in December by a coalition including the California Chamber of Commerce and the California Restaurant Association, who argue that the legislation infringes on employers’ constitutional rights and imposes undue legal liabilities.
The lawsuit points out that SB 399 attempts to regulate communication on vital workplace issues, which could lead to complications in employer-employee relations. It further contends that state-level attempts to enforce collective bargaining rights through Assembly Bill 288 encroach upon federally protected areas.
Assembly Bill 288 grants enforcement powers regarding collective bargaining rights to the state Public Employment Relations Board (PERS) in scenarios where the NLRA might not act swiftly. The plaintiffs argue that California is improperly expanding its authority over areas largely defined and protected by federal law.
The request for the injunction and the ongoing litigation reflects broader shifts in labor law administration under the current federal government, which has seen various interpretations of the NLRA evolve over time. As such, the enforcement of SB 399 will remain suspended while the case is heard in district court, with the potential for a permanent injunction based on the court’s final determination.
Representatives from the NFIB have stated the critical importance of maintaining the ability of employers to communicate openly with their employees without restrictions imposed by laws like SB 399, asserting that free speech should prevail in workplace communications.
The legislation was previously condemned as a “Job Killer” by the California Chamber of Commerce during the 2024 legislative session, highlighting the apprehensions surrounding its potential impact on job creation and business operations.
As the legal battle continues, it remains crucial for stakeholders, including employers, employees, and policymakers, to closely monitor the developments of this case and the implications it may hold for labor laws in California and beyond.
