2-What work do you do, for which you have to get up at four o'clock in the morning?

3-What is your job that you have to get up at four o'clock in the morning?
4-What work do you do that you have to get up at four o'clock in the morning?

5-What is your job, which makes you get up at four o'clock in the morning?
6-What work do you do, which makes you get up at four o'clock in the morning?

Gratefully,

All of them. If I were asked to state a preference then it would be for 3/4.

Thanks you very much Beeesneees.

How about:

7-What is your job, to have to get up at four o'clock in the morning?
8-What work do you do, to have to get up at four o'clock in the morning?

(I am sorry. I should have included these two in the first batch.)

[Beeesneees]

Those are correct too.

Could the two following sentences work maybe?

Which line of work are you in if you have to get up at 4 o'clock in the morning?
Civil aviation. I work at an airport at which the take-offs are allowed to start at as early as 6 so that the check-ins start at 5.

Thanks

[Beeesneees]

The first is okay. The second would be better recast:
Civil aviation. I work at an airport where the check-in opens at 5am for the early flights.
