DENVER (KDVR) — King Soopers and City Market have been accused of violating the agreement signed with UFCW Local 7 that ended the union’s 12-day strike in February.

The strike took place from Feb. 6 through Feb. 17. The agreement that ended the strike allowed the union to return to the bargaining table with Kroger, which owns King Soopers. The agreement also ensured for at least 100 days, Kroger cannot implement any offer, could not lock out workers during the return-to-work settlement, and the union would not take any strike actions.

The union had gone on strike after alleging unfair labor practices, with union leaders saying that the practices ranged from employee intimidation to failure to provide information on staffing to the union.

The union said Thursday that the employer has violated the agreement they signed in February.

“We agreed to end the strike and return to work and have labor peace for 100 days. The employer’s side of that agreement was that they would not implement any new terms without our agreement, lock-out workers, and would negotiate in good faith. They have failed in that commitment,” said Kim Cordova, president of UFCW Local 7, in the union’s announcement of the lawsuit’s filing.

The union said Kroger has not considered the union’s proposals and has given ultimatums “that would expire in April – months prior to the 100 day stand down running out.”

“The Employer needs to address issues of staffing, safety, raises, benefits, and other topics. King Soopers has been acting in the same manner they did before our strike – a my way or the highway approach to negotiations,” said Cordova in the union’s release. “That is not a negotiation. That is an ultimatum – one of the many things they can’t do during this good faith bargaining process.”

Cordova noted that the 100-day stand-down agreement is about halfway over. The 100 days would conclude on May 28.

“The clock is ticking,” Cordova said. “Indeed, they have and continue to take actions that drive us away from, instead of toward, a new contract. We need King Soopers & City Market to switch gears and begin to bargain in good faith and this lawsuit is about ensuring King Soopers is held accountable for failing to honor the agreement they made.”
