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

Union workers at Colorado Springs Safeway stores have voted overwhelmingly to join an unfair labor practice strike that began for workers in other cities on Sunday, June 15.

The Safeway strike in Colorado is rolling out in bits and pieces. Workers in Grand Junction joined the picket line on Tuesday, temporarily shutting down the store. A spokesperson for Safeway said the store is expected to reopen by 4 p.m. today, including the pharmacy.
