The union that represents 7,000 Safeway/Albertsons employees in Colorado terminated its contract extension with the company on Wednesday.

The bargaining committee for Safeway and Albertsons Company union workers in Colorado decided Wednesday to terminate their current contract extension, allowing a strike as early as Sunday morning.

So far, striking is limited to Estes Park, Fountain, Pueblo and a Denver distribution center after UCFW 7 members did not reach an agreement with Safeway/Albertsons.
