They did it!

The final vote tally announced Friday was 2,654 in favor of the union vs. 2,131 opposed. The Amazon workers at the JFK8 warehouse on Staten Island will need to ratify a contract to become union members, the next step in an already lengthy process that former Amazon worker Chris Smalls began last year as leader of the Amazon Labor Union.
A separate union vote brought by the Retail, Wholesale and Department Store Union in Bessemer, Ala., was tallied Thursday. The union failed to secure the vote, but it was close enough that the number of contested ballots that are still pending could change the result. The final result won’t be decided for weeks or months.
