Negotiations have ended for the week, and additional stores will go on strike in the coming days, the union representing Safeway and Albertsons workers says.

Negotiations between the Colorado union representing Safeway workers and the grocery chain have ended for the week without an agreement. Now, more stores are joining the strike, including Boulder, Lone Tree and Brighton.

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