ROBERT COHEN/ST. LOUIS POST-DISPATCH VIA AP
A Starbucks barista tries to divert customers from the drive-up window as she joins a one-day walkout involving more than 100 stores nationwide on Thursday, Nov. 17, in St. Louis, Mo. Starbucks workers at more than 100 U.S. stores say they're going on strike Thursday. It's largest labor action since a campaign to unionize Starbucks' stores began late last year.
