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.

King Soopers asked a Denver judge Tuesday to grant a temporary restraining order against striking union employees that would limit certain picketing activities.

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.
