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.

A majority of workers at a Whole Foods Market store in Philadelphia voted to join the United Food and Commercial Workers International union, giving organized labor a new foothold at parent company Amazon.

Employees at the Philadelphia’s Whole Foods store voted 130 to 100 in favor of joining a local chapter of the United Food and Commercial Workers.
