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.

The Starbucks Workers United strike continues at some locations across the United States on Christmas Eve. Several dozen locations are shut down, while many thousand remain open. The company says they are ready to get back to negotiations.
