Amazon workers on New York’s Staten Island just made history, becoming the first group to vote in favor of unionizing at a U.S. facility operated by the country’s largest e-commerce company.

After a hard-fought battle, the result is a major defeat for Amazon, which has used all of its might to keep organized labor off its premises. As of Friday, the tally at the Staten Island warehouse, known as JFK8, was 2,654 votes in favor of joining the union and 2,131 opposed, with 67 ballots being challenged.

The fulfillment center doesn’t flip to becoming a union shop overnight, and there’s potentially a long road ahead. But the wheels are in motion for change.
