More than 10,000 King Soopers grocery workers across the Denver area ended their 12-day strike late Monday after union leaders said they secured some basic protections for returning workers and agreed to resume bargaining with the Kroger-owned chain.

The Colorado chain plans to resume normal hours at its stores on Wednesday after agreeing to a 100-day “period of labor peace” with UFCW Local 7.

Pueblo King Soopers employees with the United Food and Commercial Workers Local 7 joined a statewide unfair labor practice strike on Feb. 7.

King Soopers and the union agreed late Monday night to return to the bargaining table, ending 12 days of a strike against the supermarket chain in the Denver area and Pueblo.
