BESSEMER, ALA.—Unionizing Amazon workers in Alabama received a mailer from the company with instructions imploring them to "Vote NO" on the historic union election and to then "mail the … envelope right away to make your vote count!" A USPS mailbox intended for mailing union ballots was recently installed just feet from where Amazon workers exit and enter the warehouse, a move that workers say makes them feel surveilled in the election, which is supposed to be anonymous.

In recent days, Amazon has also sent text messages imploring workers to use that on-site mailbox to cast their ballots, despite the National Labor Relations Board (NLRB) rejecting Amazon's request for in-person voting in February.
