If the woman has to ask for a sick leave, who should she turn to?

F: I have a question, Mr. Huggins. May I have a sick leave? If I can, who should I ask for?
M: Yes, you can. You can ask your department manager for permission. Remember that your leave will not delay your work or others.
F: Yes, I will. How long can I take a sick leave usually?
M: Well, it depends. If your project is very urgent and important, I bet you’d better come back as early as you can.
F: Will it affect my salary if I take a leave?
M: It will if your leave is longer than three days. And it will cut into your salary if you leave without permission.
