Amazon-owned Whole Foods is asking the National Labor Relations Board to set aside the results of a union election that led to a labor win.

Amazon, which purchased Whole Foods Market in 2017, has filed objections to last month's successful union election.

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.

Workers at a Whole Foods Market in Philly have voted to unionize, becoming the first group of employees to pull off a labor win at the chain.
