Contract talks between King Soopers and United Food and Commercial Workers union Local 7 heated up Wednesday after the labor group sued in federal court, alleging the grocery chain violated its contract by using cleaning contractors to stock shelves.
The lawsuit came as the Denver-based King Soopers proposed to increase worker wages $145 million over four years as part of a new contract with Local 7’s 17,000 employees.
