The strike by Starbucks (NASDAQ:SBUX) baristas that are members of the Workers United union ended on December 24. However, the labor issues for the coffee chain are far from over. The union organized the strike to protest a lack of progress in contract negotiations with Starbucks (SBUX).

A Starbucks barista strike is expanding to some 5,000 workers at what organizers said was more than 300 stores in 45 states, just as the company's busy holiday stretch begins. Though it still only represents approximately 3% of all U.

As Starbucks workers across the country prepare to strike, one barista explains what brought the union to this point.
