NLRB Decision and Missouri Law Advance Cannabis Worker Unionization

NLRB Ruling Extends Federal Labor Protections to State-Licensed Cannabis Employers

The National Labor Relations Board ruled May 23 that state-licensed cannabis operators fall within its jurisdiction, ending a decade-long gray zone that allowed some MSOs to claim federal labor law didn't apply to Schedule I operations. The 3-2 decision in Green Horizon Cultivation LLC v. UFCW Local 770 overturned a 2019 administrative law judge finding that had exempted a California cultivator from NLRB oversight. Schedule I classification doesn't strip workers of National Labor Relations Act protections, the Board majority held, and employers deriving revenue from state-legal cannabis commerce meet the interstate-commerce threshold for NLRB jurisdiction.

The ruling applies nationwide. Cannabis employers with annual revenue exceeding $500,000 must now recognize union elections, bargain in good faith, and refrain from unfair labor practices as defined under the NLRA. UFCW International, which represents approximately 12,000 cannabis workers across 16 states, called the decision "a watershed moment" in a May 24 statement.

Two dissenting Board members argued that federal labor protections shouldn't extend to enterprises engaged in federally illegal activity. The majority opinion emphasized that workers' rights don't hinge on their employer's compliance with the Controlled Substances Act.

Missouri Statute Bars Retaliation Against Union Organizers in Cannabis Facilities

Missouri Governor Mike Kehoe signed HB 1847 on May 20, making Missouri the first adult-use state to codify anti-retaliation protections specifically for cannabis workers engaged in union organizing. The law takes effect August 28, 2026. It prohibits licensed cannabis businesses from discharging, disciplining, or otherwise penalizing employees who participate in organizing drives, attend union meetings, or file labor grievances. Violations carry civil penalties of up to $10,000 per incident, enforceable by the Missouri Division of Cannabis Regulation.

HB 1847 passed the Missouri House 89-72 and the Senate 18-16, with support concentrated among Democrats and rural Republicans representing agricultural districts. Rep. Ashley Bland Manlove (D-Kansas City), the bill's sponsor, said in floor remarks that "cannabis workers deserve the same organizing rights as any other Missouri employee." The statute doesn't compel recognition of unions, but it removes employer tools—such as at-will termination during organizing campaigns—that labor advocates say have chilled unionization in Missouri's 191 licensed dispensaries and 86 cultivation facilities.

Missouri's law and the NLRB ruling together create the strongest federal-state framework for cannabis labor organizing since Colorado's 2014 legalization.

Implications for Multi-State Operators and Organizing Campaigns

The convergence of federal labor jurisdiction and state-level anti-retaliation statutes raises the compliance bar for MSOs operating in Missouri and other states where union campaigns are active. Curaleaf, Cresco Labs, Trulieve, and Green Thumb Industries—four of the five largest U.S. MSOs by revenue—operate facilities in Missouri. None have recognized unions at Missouri locations, according to UFCW Local 655, which has organizing drives underway at three St. Louis-area dispensaries.

Legal observers expect the NLRB decision to trigger a wave of unfair-labor-practice charges in states where cannabis employers previously asserted they were exempt from federal oversight. UFCW International reported May 24 that it's prepared filings in California, Massachusetts, Illinois, and Michigan challenging employer conduct during recent organizing campaigns.

Enforcement remains unsettled in states without Missouri-style statutes. California's Agricultural Labor Relations Board has jurisdiction over cannabis cultivation workers, but dispensary and manufacturing employees fall under NLRB oversight—a split that complicates organizing strategy for vertically integrated operators.
