Employees at an Amazon warehouse facility in Bessemer, Ala., are considering unionizing with more than 5,800 employees planning to vote on forming a union in the coming weeks. If the vote passes, this will become the first Amazon warehouse to unionize.

If the vote passes, it will be a key development for Amazon, which has famously resisted unionization at its properties and has been pressing hard for this vote to go its way.

The warehouse and logistics industry as well is watching the development closely. "It could have a tremendous domino effect, particularly if this is a successful union campaign," said Joshua Freeman, distinguished professor of history at Queens College and the Graduate Center of the City University of New York, in an interview with S&P Global Market Intelligence. "I think it could have a huge impact, not just on Amazon but across the whole industry."
