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.

With the clock winding down toward Saturday night's deadline for new contract negotiations, a Colorado union has announced locations where grocery employees are set to walk off the job on Sunday in protest.
