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

Safeway and Albertsons workers in several Colorado locations went on strike, and many more stores are expected to strike soon.

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.
