The King Soopers union worker strike ended on Monday night when both the grocery store chain and the union reached a return-to-work settlement.

According to statements from both the union and King Soopers, the agreement includes a 100-day period of “labor peace,” giving both sides time to resume contract negotiations. The truce also ensures that workers will not lose their health care coverage between now and a final contract deal.

King Soopers filed a complaint accusing the union of delaying negotiations and not bargaining in good faith. Negotiations ended Jan. 17 after the union’s contracts with the company expired and union bargainers decided against presenting King Soopers’ proposal to employees.
