Grocery workers in Denver are walking off the job today over store staffing and safety issues, marking the second strike in just three years.

Negotiations on a new collective bargaining deal date back to October 2024, with the union's previous deal having expired in January 2025.

On their second strike in three years, workers say Kroger-owned King Soopers engaged in unfair labor practices during contract negotiations.

King Soopers, a chain owned by Kroger, with 121 stores in Colorado and Wyoming, has been negotiating a new contract with the union since October.

That includes stores throughout Adams, Arapahoe, Broomfield, Denver, Douglas, and Jefferson counties as well as King Soopers stores in the cities of Boulder and Louisville.

The UFCW Local 7 Union, in Wheat Ridge, posted on social media and said Kroger meat workers voted 100% to authorize an unfair labor union practice strike. Retail workers voted 97% in favor of the strike.
