Some 300 workers at an Amazon-owned Whole Foods store in Philadelphia have voted to unionize, mirroring a pro-union shift in public opinion, according to Gallup.

The union win, at a Philadelphia store where workers are seeking higher wages, comes as Amazon is also fighting organizing efforts among some warehouse employees and delivery drivers.

Jason Buechel, who remains head of the specialty banner, steps into a new role in which he will also oversee the Amazon Fresh and Amazon Go chains.
