Workers in Estes Park, Fountain, two in Pueblo, and a Safeway distribution center in Denver, walked out on Sunday and were joined by employees from Castle Rock and the Littleton location on Mineral Ave on Monday.

United Food and Commercial Workers Local 7 announced Saturday that, unlike the February strike by King Soopers workers, the Safeway/Albertsons walkout will begin on a more limited scale.

Supermarket workers in four cities are fighting against understaffed stores, changes to health benefits, and insufficient wage increases.
