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’s Whole Foods says Trump’s firings that paralyzed a federal labor regulator invalidate a union vote at a Philadelphia store.

Workers at a Pennsylvania Whole Foods store voted on Monday to unionize, forming the first union in the organic grocery chain owned by Amazon.

Whole Foods workers in a Pennsylvania store vote to form the first union under Amazon ownership, joining a local chapter of the UFCW.

Now, a battle lies ahead when working out the first contract between Whole Foods and the unionized workers. "This is going to be the longest uphill battle of our lives, but this is not just for us. This is for the people who come behind us and for the people who have been here," said Khy Adams, a Whole Foods employee.

Last month, workers at a Whole Foods store in Philadelphia voted in favor of joining the United Food and Commercial Workers Union.
