More than 1,000 Starbucks workers will go on strike at about 65 stores scattered across states as far-flung as California, Texas and Pennsylvania, Starbucks Workers United (SWU), the union representing the workers, told ABC News in a statement.

Unionized Starbucks baristas are launching a wave of walkouts, a work stoppage they say could grow to become their biggest strike to date.

The strike was scheduled to disrupt Starbucks’ Red Cup Day, which is typically one of the company’s busiest days of the year.
