DENVER (AP) — 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 sellout and premature cancellation of the two-week strike called on February 6 breaks the momentum of the strike and secures no real gains for workers, only an agreement to restart negotiations over the next 100 days.

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.
