whose job is or whose job it is

[Fujibei]

Which of the following is correct and common?

1) I know a guy whose job is to teach English.
2) I know a guy whose job it is to teach English.
3) I know a guy whose job is teaching English.

Here are some quotes from the Ney York times:
1) Under the proposal, almost anyone whose job is to ferret out corporate wrongdoing,...
2) That question is characteristic of Japanese engineers, whose job it is to overcome technological hurdles rather than seek profits.

Any difference between "whose job is..." and "whose job it is..." in the above quotes?

[English Freak]

Numbers 1 and 3 are correct. No. 2 is not right because the original sentences are:
I know a guy. His job is to teach English.
When you combine them using a relative pronoun, you should say:
I know a guy whose job is to teach English.

Looks fine to me. (Perhaps we don't use your rules over here. )

b

[Bennevis]

All three are correct. But the 3rd variant is the one I'd go with in real life.

All of them are correct?!!! How can No. 2 (I know a guy whose job it is to teach English.) be correct? What is the use of "it" in the sentence?!

You get it from the original sentences, as you say. In this case, they are:
I know a guy. It's the guy's job to teach English.

Sorry, but I don't understand it. Maybe because it's past midnight now in Iran!

ATTENTION: NOT A TEACHER


Here is how I explain it to myself. I do not claim that I am correct.

(1) Two sentences: A journalist is a person. His job is to report the news.

Sentence combining: A journalist is a person whose job is to report the news.

***

(2) Two sentences: A journalist is a person. It is her job to report the news.

Unacceptable combining: A journalist is a person it is whose job to report the news.

Acceptable combining: A journalist is a person whose job it is to report the news.
