Well, that all depends on how you are modeling your objects and your users.

It's the "classic" example that many OO gurus pull people up about and point out that "manager extends user" is 'wrong' - Coad, Booch, Rumbaugh, Jacobson etc have all picked on this example.


Like most folks, I used to do it that way ("manager extends user") too until I took the gurus' advice to heart. Coad's "Java Modeling in Color in UML" is a great book that explains this sort of stuff in a really approachable manner.
