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.

Workers at certain Safeway and Albertsons locations will begin striking on Sunday, in protest of what workers say are unfair labor practices, short-staffed stores, and frozen wages.

Currently, unfair labor practice strikes are limited to Safeway/Albertsons locations in just four cities: stores in Estes Park, Fountain and Pueblo, and a distribution center in Denver.
