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.

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.

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.
