Yesterday was what I used to observe as "Secretaries Day". See this official explanation of the day and week , see this in Slate for a view from the other side.
My impression is that secretaries are an endangered species. 21 years ago in a computer training session for professional I was told: "I don't type". I doubt many would say that today (although Michael Chertoff doesn't use e-mail). I recently read a book on Eisenhower as President. (I think it was called "the Hidden Hand" but I'm too lazy to look it up. It was one of the first books to renovate Ike's reputation on the basis of his work behind the scenes.) It was written in the early 80's and the author included in the acknowledgments a nod to his secretary for typing the manuscript. That used to be commonplace but no more.
