M: Hi, Sue, how are things?
W: Fine.
M: OK, now, about the change in your work routine, you’re going to work Saturdays from next week.
W: Yes, but why should I have to work on Saturdays. No one told me why.
M: I’m sorry, this should have been explained to you.[19]We get a lot of people calling now on Saturdays for information about our products — it’s important that we answer these questions. Is that ok? Any more questions?
W: No, ok.
M: Great. Well, how’s your course coming along?[20]You’re learning how to make websites.
W: The course is great, and it’s not that difficult. I’m helping my son make a website at home.
M: Great. You’ll be able to work on our site soon then.
W: Hmm... Are there any other courses I can take after the website designer course finishes?
M: There are one or two courses that could be useful. Let’s talk about it when you’ve finished the web course.
W: OK. You know, Bob, I’d like to say something.[21]Don’t you think it would be a good idea to discuss things together, like having a meeting in our department? I think in doing so we could come up with some great ideas on how to improve things here.
M: I agree, Sue. It would be good for everyone to meet together. You know the problem is that we haven’t got a room big enough for us all to meet together.
