Machinists who service equipment at Amazon.com's sprawling Middletown, Del. warehouse have filed with the National Labor Relations Board for a union representation election, which has been scheduled for Jan. 16, the Wilmington, Del. News Journal says here.

International Association of Machinists organizers say a Yes vote would mark the first unionization at an Amazon plant. The works employs more than 1,600 fulltime workers and hundreds more during the Christmas shopping season; most won't be covered under the January vote.
