Safeway workers in several Colorado cities entered the third day of labor strikes Tuesday against Safeway and Albertsons over alleged unfair labor practices, with picketing in Grand Junction prompting a temporary store closure.

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

Picket lines are continuing to form at four Safeway grocery stores across the state, including two here in southern Colorado. Yesterday, workers were seen picketing in front of a distribution center in Denver.
