Grocery workers in several Colorado cities entered their 18th day of a strike Wednesday against Safeway and parent company Albertsons. The United Food and Commercial Workers Local 7 resumed negotiations, but after exchanging numerous proposals, the union said the company remained unwilling to offer an agreement that meets the needs of workers.

If union members ratify the agreement, it would end five months of negotiations and the looming concern of how a strike by 16,000 union workers could impact operations at over 100 Safeway grocery stores across the Bay Area.
