The JBS Greeley strike that began on March 16, 2026 came to a temporary halt when thousands of workers at the Swift Beef Co. plant agreed to return to work on April 7 after the company agreed to resume contract negotiations later in the week. The walkout, organized by the United Food and Commercial Workers Local 7 union, was the first strike at a U.S. slaughterhouse since workers walked out at a Hormel plant in Minnesota in 1985. That earlier strike lasted more than a year and included violent confrontations between police and protesters.
The JBS Greeley strike ended without a new contract in place. JBS USA said its last, best and final offer remained on the table and expressed hope that workers would have the opportunity to review and vote on it soon. Union president Kim Cordova made clear the pause was tactical rather than a sign of defeat, saying that workers remain united and will continue to fight for higher wages and better health care coverage. The company had offered less than 2% per year in wage increases, which union officials said was below the rate of inflation in Colorado.
Why the JBS Greeley strike matters for the U.S. beef supply?
The Greeley plant handles approximately 6% of total U.S. beef slaughter capacity, according to Abby Greiman, a livestock market adviser at industry consultant Ever.Ag. That share made the JBS Greeley strike one of the most consequential labor actions in recent agricultural history. Three weeks of idled operations at a facility of that scale removed a significant volume of cattle from the processing pipeline at precisely the moment the U.S. beef supply was already under severe pressure from a national herd at a 75-year low.
JBS is the world’s largest meatpacking company with a market capitalization of $17 billion, and the Greeley plant is the top employer in its host city of roughly 114,000 people located about 50 miles northeast of Denver. The strike coincided with January’s closure of a Tyson Foods meatpacking plant in Lexington, Nebraska, which the company attributed to the smaller national cattle herd and projected financial losses. The two plant disruptions together contributed to a beef supply squeeze that has pushed retail ground beef prices to multi-year highs, according to data from the Bureau of Labor Statistics.

What workers and management said about the JBS Greeley strike dispute?
The grievances behind the JBS Greeley strike went beyond wages. Union general counsel Matt Shechter said company management tried to intimidate workers into leaving the union through one-on-one meetings, a practice union officials characterized as an unfair labor practice. JBS USA denied any labor law violations and maintained its contract offer was fair. The company’s offer of under 2% in annual wage increases was described by union officials as inadequate given Colorado’s cost of living, and workers walked out to demand both higher pay and improved health care benefits.
Jennifer Martin at Colorado State University’s animal sciences department noted that an extended strike threatened to disrupt the broader industry in ways that could ultimately push prices higher across the supply chain. The UFCW Local 7 union’s decision to halt the strike in exchange for resumed talks suggests both sides recognized the pressure to reach an agreement, though the underlying contract dispute remains unresolved with workers now back on the floor and negotiations set to continue.
JBS faces scrutiny beyond the Greeley plant
The JBS Greeley strike is not the only legal or regulatory matter the company has been managing. JBS shares were approved for trading on the New York Stock Exchange in May 2025 despite opposition from environmental groups and a federal probe that resulted in the company’s guilty plea in October for bribing Brazilian officials for financing used in its U.S. expansion. The company now operates within a beef market environment where the structural shortage of cattle, the closure of competing processing plants, and ongoing labor tensions are creating simultaneous headwinds across the industry.
With workers back at the Greeley facility and negotiations scheduled to resume, the immediate pressure on beef slaughter capacity from the JBS Greeley strike has eased. However, the underlying contract issues — wages, health care, and union rights claims — remain unresolved, leaving open the possibility of further action if talks break down again. The original report on the strike pause was published by KUNC via the Associated Press on April 6, 2026.
