Who might the man be?

W: Sang-ho, what do I need to do to get some time off?
M: You just need to let a manager know what days you need. As long as it doesn’t affect our work schedule, they’ll approve it. It’s quite easy.
W: How long can I request time off for? I need to go out of town for a little while, but it all depends on work.
M: I don’t know. I guess a week or two. You should talk to Sarah about it. She’s the easiest to talk to. The longest time off I requested was 10 days when I went home to visit my family.
