Workers at a Denver-based meat processing plant have voted to authorize a strike, claiming unfair labor practices. 

The union said 97% of union members at Denver Processing voted to authorize the strike, meaning they are prepared to walk off the job if they aren’t able to reach a contract agreement with the company. The dates of a potential strike have not yet been determined.

Denver Processing is a beef and pork processing plant that supplies meat products to Kroger stories throughout the southwestern United States. It is a subsidiary of JBS, where nearly 4,000 workers walked off the job last month. That strike lasted three weeks before union members ratified a new two-year collective bargaining agreement on April 12.

A release from United Food and Commercial Workers Local 7, the union representing Denver Processing workers, says they believe the company retaliated against a union member by disciplining them for attending bargaining sessions. The union also believes the company is stalling negotiations and engaging in bad-faith bargaining, according to the release.
