A federal judge has granted conditional class-action status to a lawsuit filed on behalf of an estimated 700 workers at a slaughterhouse in south-central Kansas.

U.S. District Judge Eric Melgren ruled Monday that the class would include all hourly production employees subjected to allegedly unfair compensation practices at Creekstone Farms Premium Beef in Arkansas City for the past three years.

The workers claim the company hasn’t been paying employees for all the time they spend working. Creekstone contends it has paid employees for all time worked and any overtime they were entitled to get.

Melgren ordered the company to give the plaintiffs the names and contact information for each member of the class and to post notice of the lawsuit in both English and Spanish at its facility.
