The union representing thousands of grocery store workers in Colorado and Wyoming says it's reached a tentative deal with Safeway to end a strike impacting unionized workers at around 50 stores across Colorado.

In the post announcing the end of the strike, the union described the tentative contract as “all gains, no concessions.”

After 20 days on the picket lines, Pueblo and Pueblo West Safeway workers are back to work. Here's what to know about the tentative agreement.
