GREELEY, Colo. (AP) — Around 3,800 workers at one of the largest meatpacking facilities in the U.S. have begun a strike at the Swift Beef Co. plant in Greeley, Colorado, marking the first walkout at a U.S. beef slaughterhouse in 40 years.

As dawn broke on Monday, hundreds of workers gathered outside the plant, shaking off the cold while chanting 'huelga!'—Spanish for 'strike'—and holding signs urging consumers not to patronize JBS. The strike comes on the heels of accusations of unfair labor practices and retaliation against workers during contract negotiations.

Leticia Avalos, a union steward who has worked at the plant since 2020, emphasized the importance of the strike, stating, They don’t really value their workers and we’re the ones that help them get all their profit.

The labor action follows the expiration of a previous contract and reflects growing frustrations among workers over wages and working conditions. Reports suggest that some employees have been charged over $1,100 for necessary personal protective equipment.

The union leading the strike pleads for better wages that keep pace with rising living costs and healthcare provisions that reflect the challenging nature of their work. President of the union, Kim Cordova, confirmed that an overwhelming 99% of workers voted in favor of the strike, and plans are in place to maintain a strong presence on the picket line.

This strike is particularly noteworthy as it comes during a time of low U.S. cattle population, contributing to soaring beef prices, which have been exacerbated by recent droughts and trade tariffs.

Workers claim they perform some of the most dangerous jobs in the country, and they are determined to make their voices heard as the company has been accused of trying to intimidate them during labor negotiations.

JBS USA maintains that its contract offers are fair and claims to comply with labor laws, stating that those who choose not to strike will continue to be employed. Meanwhile, the implications of this strike are expected to ripple throughout the community, known as the heart of Greeley’s economy.
