Stores in Colorado Springs, Fort Collins, Greeley and Longmont will hold strike-authorization votes tonight and tomorrow morning.

The Safeway/Alberstons workers' strike is quickly gaining momentum, as employees join together to fight against understaffing, insufficient wage increases, and inadequate health benefits.

Safeway employees at a Denver store walked out Monday, expanding a strike that started this weekend. The strike started small with workers at three stores in Estes Park, Fountain and Pueblo, and a Denver distribution center.
