St. Louis Cannabis Workers Win National Precedent for Union Rights
A St. Louis cannabis company’s failed challenge sets national precedent as federal labor board rejects agricultural exemptions for marijuana processing workers.

ST. LOUIS, MISSOURI β A St. Louis marijuana company’s failed legal challenge to block worker unionization has set a national precedent favoring cannabis processing employees, according to a National Labor Relations Board decision issued April 23.
The NLRB rejected arguments from BeLeaf Medical, which operates the Sinse cultivation facility in St. Louis, that post-harvest cannabis workers should be classified as agricultural employees without federal union protections. The company had maintained this position since 2023, arguing that workers who process marijuana after harvest fall under agricultural exemptions that deny unionization rights.
“We agree with the Regional [NLRB] Director, for the reasons provided in her decision, that none of the workers employed in the classifications at issue here are agricultural laborers under the secondary definition of agriculture,” the national board members stated.
Missouri Strengthens Cannabis Worker Protections
The federal ruling coincided with Missouri Governor Mike Kehoe signing legislation on April 23 that guarantees unionization rights for all cannabis workers in the state, including those involved in marijuana cultivation. The new state law provides additional protections beyond the federal decision.
Agricultural workers who grow crops, including cannabis, typically lack federal protections that ensure employees can organize without facing employer retaliation. The NLRB’s decision clarifies that workers involved in post-harvest cannabis processing deserve the same union rights as other industrial employees.
Two-Year Legal Battle Over Worker Votes
The Sinse facility employees voted to unionize more than two years ago, but the majority of ballots have remained sealed due to BeLeaf’s legal challenges. Of the 16 total votes cast during the February 2024 election, BeLeaf contested 11 ballots, preventing their counting while the company pursued its agricultural worker argument.
The contested employees primarily worked in pre-roll production and data entry operations, according to previous reporting on the case. Marilyn Gleason, BeLeaf Medical’s director of human resources, participated in the ballot sealing process during the disputed election.
The prolonged legal dispute has kept workers in limbo while the company challenged their eligibility for union representation. With the NLRB’s definitive ruling, the contested ballots can now be opened and counted to determine the final union election outcome.
National Implications for Cannabis Industry
The decision sets an important precedent for cannabis workers nationwide as the industry continues expanding across states with legal marijuana programs. Labor organizers view the ruling as confirmation that cannabis processing employees deserve the same workplace protections as workers in other manufacturing sectors.
The National Labor Relations Board serves as the highest administrative authority on labor disputes and creates binding policy for unionization rights across industries. Their rejection of BeLeaf’s agricultural exemption argument will likely influence similar cases in other states where cannabis companies attempt to limit worker organizing.
BeLeaf Medical has not announced whether it will pursue further appeals of the federal labor board’s decision. The company’s Sinse cultivation facility continues operations while workers await the final resolution of their two-year unionization effort.
