Missouri Cannabis Operators Face Spreading Union Wins

Missouri’s cannabis companies are losing the argument they relied on to keep unions off the production floor, and the cost of that loss is starting to show up in contracts. Dispensary workers at a High Profile Cannabis store in Columbia have ratified what organizers call the state’s first union contract for cannabis workers, winning higher pay and paid vacation time. Around the same time, processing workers at Proper Brands in St. Louis voted to unionize. A third operator, Vibe Cannabis, is scheduled to hold its own election before the end of July 2026.

Missouri’s recreational market, legal since 2023, added thousands of cannabis jobs almost overnight, and a unionization push followed close behind. What stalled it was a single legal question that a federal labor decision settled this spring, stripping operators of their cleanest defense.

The classification defense collapses

For years, Missouri operators fighting union drives leaned on the same claim: that employees who trim, cure, and package cannabis are “agricultural laborers,” a category federal law excludes from the guarantee that most private-sector workers can organize without retaliation. On April 23, 2026, the National Labor Relations Board rejected that argument in a case involving BeLeaf Medical‘s Sinse cultivation facility in St. Louis, declining to disturb a regional finding that post-harvest work is industrial processing, not farming. It was the board’s first ruling on the question, and while it framed the call as case-by-case rather than a blanket rule, it took away the operators’ strongest line of defense.

The Sinse workers’ win followed a nearly three-year fight in which BeLeaf spent heavily on outside attorneys to contest the ballots. The same day the board acted, Missouri’s governor signed a state law codifying the same distinction, declaring that cannabis work — including jobs inside climate-controlled indoor cultivation and processing sites — is not agricultural labor for collective-bargaining purposes. Growers who tend the plant remain exempt under federal law, and dispensary counter staff were already covered. The contested middle, the workers who turn raw flower into pre-rolls, vapes, and packaged goods, now sits inside federal protection in both venues.

What a first contract changes

The Columbia agreement is the first read on what that shift costs an operator. High Profile Cannabis, the retail brand of privately held multistate operator C3 Industries, now works under a contract that lifts pay and adds paid vacation — terms it can no longer set on its own. In a market where wholesale prices have fallen and retail margins are thin, a negotiated wage floor converts labor from a cost management can adjust quarter to quarter into a fixed obligation carried on the books.

Operators are splitting on how to respond. Proper Brands, whose post-harvest workers voted 25-21 to unionize on July 1, 2026, took a conciliatory line; founder and CEO John Pennington said the company respects the outcome and expects to work with the union on a first contract. That is a different posture from the multiyear ballot fight BeLeaf Medical waged and lost — an approach that delayed organizing but added legal cost without changing the result.

BeLeaf is no marginal player. The Earth City company runs three cultivation sites, two manufacturing plants, and a dozen SWADE dispensaries, and markets itself as the state’s leading operator. That scale cuts both ways now: vertical integration, long prized as a margin advantage, also means more organizable workforces under one corporate roof, with cultivation, processing, and retail each a potential bargaining unit.

The union reads the sequence as self-reinforcing. “They basically thought it was impossible when all these companies were fighting, and now the workers are winning,” said Sean Shannon, organizing director at UFCW Local 655, which represents all three groups of workers.

What operators should watch

The board’s case-by-case standard leaves one narrow opening: labor attorneys have noted that companies could try to redesign job duties so processing roles look more agricultural. That path cuts against both the new federal precedent and the state statute, and it does little once a workforce has already filed to vote — a step more workers are now taking across the state.

Because the decision is the first at the national level, its logic reaches beyond Missouri. Most states give farm workers no federal organizing path, but the ruling signals that processing and manufacturing employees — the backbone of any vertically integrated operator — generally do have one. That matters for a company like C3, which runs cultivation, manufacturing, and retail across seven states.

The next marker is Vibe Cannabis, whose post-harvest workers at its St. Louis cultivation and manufacturing plant filed to organize in June 2026 after disputes over holiday scheduling and safety conditions. Their bargaining wish list — respirator access, a 401(k) option, and pay parity with better-paid departments — previews the kind of terms operators across the state may soon be negotiating rather than setting. A win at Vibe would make it four Missouri operators inside a matter of weeks.
