Cannabis Workers, Agricultural Labor, And The NLRB: How One Missouri Union Fight Could Reshape Labor Law Across The Industry

A labor dispute inside a St. Louis cannabis facility has evolved into one of the most consequential labor law battles the cannabis industry has faced since legalization began expanding across the United States.

At the center of the case is a deceptively narrow legal question with potentially national implications:

Are cannabis post-harvest workers considered agricultural laborers under federal labor law, or are they statutory employees entitled to organize under the National Labor Relations Act?

The answer could reshape unionization efforts across cultivation, processing, packaging, and manufacturing operations throughout the legal cannabis industry.

In April 2026, the National Labor Relations Board denied BeLeaf Medical’s request for review in a closely watched case involving post-harvest employees at the company’s Sinse cultivation facility in St. Louis, effectively allowing the workers to unionize.

The ruling followed nearly two years of litigation, administrative hearings, and appeals that labor organizers, cannabis operators, and attorneys nationwide were monitoring closely.

“This would be the first time that the national board weighs in on the issue, setting a national legal precedent,” Missouri Independent reporter Rebecca Rivas wrote in 2024 while the case was still pending.

For labor advocates, the decision could significantly expand organizing rights within cannabis production facilities.

For operators, it raises new legal, operational, and economic questions about how cannabis businesses are classified under federal law.

The Core Legal Question: Are Cannabis Workers “Agricultural Laborers”?

Under Section 2(3) of the National Labor Relations Act, agricultural laborers are excluded from the definition of “employee,” meaning they are not protected by federal collective bargaining law.

That exemption traces back to the Fair Labor Standards Act’s definition of agriculture, which includes traditional farming activities such as cultivation, growing, and harvesting, along with practices performed “as an incident to or in conjunction with such farming operations.”

BeLeaf argued that workers inside its post-harvest department were still handling “raw flower” and therefore fell within the agricultural exemption.

The workers and the union representing them, United Food & Commercial Workers Local 655, argued the opposite: that the employees were engaged in industrial processing and manufacturing activities that transformed cannabis into finished retail products.

The distinction matters enormously because agricultural laborers do not receive federal protections guaranteeing the right to organize without retaliation.

Inside The Sinse Post-Harvest Operation

According to the NLRB decision, BeLeaf operates three cultivation facilities and five dispensaries in Missouri.

The Cherokee Street facility in St. Louis contains six flower rooms where cannabis plants are cultivated before moving downstream into harvesting, drying, de-stemming, trimming, curing, packaging, preroll production, and fulfillment operations.

The case focused specifically on 13 post-harvest employees working in four classifications:

• Post-Harvest Technicians
• Post-Harvest Leads
• Post-Harvest Trim Leads
• Post-Harvest METRC Specialists

The Board’s detailed factual findings described an operation that looked increasingly industrialized once harvested cannabis entered the post-harvest workflow.

Employees:

• removed branches from dried plants,
• mechanically separated buds,
• operated trimming machinery,
• weighed biomass,
• logged regulatory compliance data into METRC,
• cured cannabis,
• packaged flowers into retail units,
• and produced between 900 and 1,200 prerolls daily.

Some workers reportedly spent 70% to 90% of their time on computers, handling compliance and inventory-tracking functions.

The NLRB repeatedly emphasized that these activities occurred in separate rooms and departments distinct from cultivation operations.

Why The NLRB Said Cannabis Processing Is More Like Manufacturing

Regional Director Andrea Wilkes concluded that the post-harvest work was not simply “preparation for market” but rather a transformative industrial process that altered cannabis from its natural state into finished products prepared for sale.

“In sum, the Employer’s Post-Harvest production process is not a mere preparation for market but a process that utilizes industrialized processes to transform the marijuana from its natural state into finished products prepared for sale,” Wilkes wrote.

The ruling relied heavily on decades of agricultural labor precedent involving tobacco, sugar, mushrooms, and other agricultural commodities.

One of the most important comparisons involved tobacco processing.

Wilkes cited federal precedent holding that removing veins from tobacco leaves and fermenting them moved the product beyond agriculture into manufacturing.

She found cannabis processing sufficiently analogous.

“Marijuana processing bears enough resemblance to tobacco processing that the comparison is compelling,” the decision stated.

The ruling repeatedly focused on whether cannabis remained in its “raw and natural state,” a key legal test developed through decades of federal labor jurisprudence.

Packaging, Prerolls, And METRC Became Central To The Decision

Several specific operational activities became especially important in the Board’s analysis.

Packaging

The Board distinguished cannabis packaging from ordinary agricultural packaging operations, such as boxing fruits or vegetables.

Instead, the Board described the process as “precise dosing out of a product in preparation for sale.”

Workers packaged cannabis into:

• 1 gram,
• 3.5 gram,
• 7 gram,
• and 14 gram retail units.

The Board found this resembled commercial manufacturing and retail preparation more than traditional agricultural sorting.

Pre-Rolls

The Board was even more direct regarding preroll manufacturing.

Cannabis flower was placed into a knock-box machine that mechanically filled cones with exactly one gram of cannabis at a time.

The Board described preroll creation as:

• mechanized,
• factory-like,
• value-added,
• and capable of operating as an independent business.

“The task of creating pre-rolls is undoubtedly non-agricultural,” the decision stated.

METRC Compliance Work

The Board also emphasized the role of regulatory compliance.

METRC specialists spent most of their time entering compliance data, managing inventory tracking, and satisfying Missouri’s seed-to-sale requirements.

The Board concluded these administrative functions were not agricultural activities performed “incident to or in conjunction with” farming operations.

BeLeaf’s Argument: Cannabis Remains A Raw Agricultural Product

BeLeaf argued the NLRB’s tobacco comparison was legally flawed.

“The regional director’s analysis is flawed,” the company argued in its appeal. “The post-harvest de-stemming and other processes bear no resemblance to de-stemming tobacco leaves.”

The company maintained that cannabis remained in its raw natural state throughout post-harvest processing.

“The raw cannabis plant remains in the same, natural state throughout the entire post-harvest process,” the company argued.

BeLeaf also argued that curing preserved cannabis rather than transforming it chemically.

The company attempted to distinguish cannabis from heavily processed agricultural products like tobacco or sugar.

But the Board ultimately rejected those arguments.

Why The Case Could Affect Cannabis Operators Nationwide

The significance of the decision extends well beyond Missouri.

Cannabis operators nationwide have frequently argued that cultivation and processing workers qualify as agricultural laborers exempt from federal labor protections.

“I know for a fact that people in these facilities are told, ‘You’re ag workers. You don’t have any rights,’ no matter what position they are,” UFCW organizer Sean Shannon told Missouri Independent.

The BeLeaf ruling may now weaken those arguments substantially, particularly for:

• post-harvest departments,
• manufacturing operations,
• packaging facilities,
• compliance staff,
• and preroll production teams.

Labor attorney Jeff Toppel described the ruling as “significant” and said it “could have a wide-ranging impact.”

Still, the Board emphasized the inquiry remains highly fact-specific.

Member Scott Mayer, concurring in the Board’s denial of review, stressed that determining agricultural status requires a “fact-intensive, case-by-case inquiry.”

That caveat may become critically important as future cases emerge involving:

• outdoor cultivation,
• vertically integrated operators,
• extraction labs,
• manufacturing centers,
• or different post-harvest workflows.

The Decision Is Already Reshaping Union Activity In Missouri

The ruling appears to already be accelerating labor organizing activity.

The legal battle formally culminated in May 2026 when sealed ballots from the Sinse union election were finally opened after nearly two years of litigation. The final vote was 11-3 in favor of unionization. Former Sinse employee Will Braddum said the outcome could extend well beyond a single facility.

“It’s really nice to have changed the industry for the better,” Braddum said after the vote count was finalized. “At least they have the opportunity now. It sets a precedent.”

Following the decision, BeLeaf Medical said it respected the election results and intended to bargain with workers.

“BeLeaf Medical is committed to bargaining in good faith,” Douglas Purvis, the company’s director of human resources, said in a statement.

In May 2026, workers at Proper Cannabis also filed a petition seeking a union election shortly after the BeLeaf ruling.

Workers cited:

• pay disparities,
• job security,
• workplace conditions,
• and air-quality concerns related to mold exposure.

“Thanks to the recent NLRB ruling, we have the opportunity to sit at the table and make it better for us and the others to come,” Proper employee Katie Hazelwonder said.

The momentum coincided with new Missouri legislation signed by Gov. Mike Kehoe explicitly stating that cannabis industry employment “is not ‘agricultural labor’” for purposes of collective bargaining protections.

A New Labor Era For Cannabis?

The BeLeaf case illustrates how cannabis legalization is increasingly forcing federal labor law to confront questions lawmakers never anticipated when many foundational labor statutes were written nearly a century ago.

At its core, the dispute reflects a larger identity crisis within the cannabis industry itself:

Is cannabis cultivation primarily agriculture, pharmaceutical manufacturing, consumer packaged goods production, or some hybrid of all three?

The answer may ultimately shape:

• unionization rights,
• labor costs,
• compliance obligations,
• operational structures,
• and workforce dynamics throughout the legal cannabis industry for years to come.
