Amazon workers in Bessemer, Alabama, will get a second chance to form a union when voting begins on Friday, February 4.

The NRLB invalidated the results of last year’s election, ruling that Amazon illegally interfered in the vote. Amazon installed a large mailbox outside the warehouse in violation of an explicit order from the NLRB, and the company pressured workers to submitting ballots at the box which many suspected was being watched.

But this time, workers say they are confident the result will be different. They have been openly organizing and confronting union-busters at the warehouse.

“That has done wonders…to shift the attitude toward the union,” they told reporter Kim Kelley.

If the vote passes, it will be the first Amazon warehouse to unionize in the United States.
