Dean Baker on the union maid

As I've noted before, unions get little attention in the micro principles textbooks. In the Canadian edition of Mankiw on my bookshelf, unions appear in one paragraph as a cause of unemployment. That's it.
   In contrast, Dean Baker has a nice column in The Guardian pointing out that the union membership of the maid in Dominique Strauss-Kahn's New York hotel might have been of critical importance in preventing her from becoming unemployed -- by giving her enough protection against arbitrary firing to make a complaint.
