Who most likely are the listeners?

Hi, I’m Mark Spender from Human Resources. I will be taking you on a tour of our facilities, starting at the shop floor in this building. As you can see, this is where our company’s products are made. Up ahead is the Delivery section from where our products go out into the market. On the first floor we have the Accounting section. Let’s now go into Human Resources to collect your employee identification badges. Once you’ve received the badges, we’ll go into the cafeteria for a cup of coffee, and I’ll be happy to answer any questions that you may have.
