Who is John in the dialog?

W: What a busy day! I’m glad you are here. We have to work overtime today.
M: Oh, terrible! But frankly speaking, John is an easy boss to work for, isn’t he?
W: Absolutely! I have never had a better one. I don’t mind doing extra work for John, and his management style is completely different.
M: Yes. He is creative. He give us a task to do, and let’s us decide how to do it.
