Description: Union Democracy: The Internal Politics of the International Typographical Union is a book by Seymour Martin Lipset, Martin Trow and James S. Coleman, originally published by New York Free Press in 1956.

The book is a case study of one particular organization: the International Typographical Union, an organization seen by the authors as the most democratic one in the contemporary (1950s) United States; an organization that seemingly disproved Robert Michels' Iron law of oligarchy. -Wikipedia
