Bankers Boxes—A New Perspective
If you are talking about actual bankers, and the actual bankers have boxes, bankers’ boxes is what you want to write. Bankers’ is plural and possessive—that’s why you need an apostrophe after the s.
BUT, as one reader pointed out in a comment on my Plural Possessive—Bankers’ Boxes post, Bankers Box is a trademarked brand name, and when you refer to the actual boxes known by this name (and not the actual bankers), Bankers Boxes is what you want to write.
See the distinction? I do—now.
