Starbucks workers vote for a union at first store in Seattle

Starbucks workers at a store in Seattle have voted 9 to 0 to join a union, a first in the city and state where the coffee chain is headquartered and bringing closer to home a burgeoning labor movement among its workers that stretches across the country.

"We're excited for what this means for the national movement, and specifically Seattle," Rachel Ybarra, a 22-year-old barista who has worked at the newly unionized store for nearly two years, said in a news conference after the voting results were announced. "There's a support system now that did not exist a year ago."

One ballot was challenged and not opened, with three ballots not returned, a webcast of Tuesday's counting by the National Labor Relations Board, or NLRB.
