HARPER’S divided by union fight. “The Harper’s union has been locked in a bitter dispute with MacArthur since July. And now he’s trying to lay off Harper’s’ literary editor, Ben Metcalf, who’s worked at the magazine since the mid-nineties and who played a key role in the union drive — a move the union says is pure retaliation. The current crisis began a year ago, when MacArthur fired the magazine’s editor-in-chief, Roger Hodge. The two men had once been close, but their relationship had frayed as the red ink mounted: Newsstand sales dropped, MacArthur’s appetite for losses waned, and Hodge tried to defend the staff from cuts.” Plus, bashing the Internet.
