How long has the man been working here?

W: Hello, I’m Jennifer. I’m new here.
M: Nice to meet you, Jennifer. I’m David. I just had my first month here. Are you seasonal helper too?
W: Yes, but I hope I can stay on after the holidays.
M: Me too. It depends on us in part. We have to do a good job and go the extra mile.
W: I agree. Hard work will finally pay off.
M: Right. You know, the manager of the shoe department started just two years ago as a temporary worker. He’s about our age. I bet you will be the manager of the company someday.
W: I like to have a career in fashion design. There is a lot of opportunity for advancement.
M: I want to owe my own store one day, so I want to learn all I can.
W: I’m taking designing classes in college. There’s a lot to learn.
M: It’s a hard work, but it has rewards. I find satisfaction in doing a job well.
W: If you enjoy doing something, it’s easier. I just finished watching the orientation videos. Now I’m training on the computers. It’s fun so far.
M: Yes, it is. Oh! It looks like my break is almost over. I need to work now. It’s been nice talking to you.
