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

With the clock winding down toward Saturday night's deadline for new contract negotiations, a Colorado union has announced locations where grocery employees are set to walk off the job on Sunday in protest.

Safeway workers in Colorado Springs will join strikes happening around the state. That's according to the UFCW Local 7 union.

On Tuesday, members of the UFCW Local 7 held a vote to authorize a strike for more stores. Colorado Springs meat and retail workers voted 99% in favor of striking, according to a social media post from the union. They will join the employees at the Fountain Safeway and one location in Pueblo, who began their picket lines over the weekend.

Pueblo and Pueblo West Safeway workers have joined a United Food and Commercial Workers Local 7 strike seeking better pay, staffing and benefits.
