Earlier, Starbucks said the union “prematurely ended” a bargaining session and called for talks to continue. The coffee chain has said it’s focused on improving workers’ experience and that baristas who work at least 20 hours a week receive $30 an hour, on average, when combining pay and benefits.

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.

Starbucks' union says workers are walking off the job at some 300 — out of over 10,000 — stores across the U.S. as contract negotiations falter. The company urges it to return to the bargaining table.
