Starbucks workers plan nationwide, three-day strike in ongoing effort to unionize

Starbucks workers in 100 to the coffee chain's U.S. plan to go on strike for three days starting Friday in their ongoing effort to unionize. 

Starbucks Workers United says over 1,000 baristas are planning to walkout, in what will be the longest strike the unionization campaign.

In November, workers at 110 Starbucks stores staged a one-day walkout toward unionization efforts.

Over 264 of Starbucks’ 9,000 company-run U.S. stores voted to unionize since late last year.

Tori Tambellini, a former Starbucks shift supervisor and union organizer, says workers are protesting understaffed stores and poor management. 

The National Labor Relations Board, Workers United filed at least 446 unfair labor practice charges against Starbucks since late last year, the Associated Press reports.

One charge alleges Starbucks has fired labor organizers.
