Workers at a Whole Foods Market in Pennsylvania voted to unionize on Monday, becoming the first group of employees to pull off a labor win at the Amazon-owned grocery store chain. Employees at the Philadelphia store cast 130 votes — or about 57% of the ballots cast — in favor of joining a local chapter of The United Food and Commercial Workers

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.

Workers at Philadelphia's Center City Whole Foods store voted on Monday to unionize, becoming the first local store in the chain owned by Amazon to formally organize under the United Food and Commercial Workers.

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