Of course Jake was Emily's boss and if he asked she would have to abandon what she was doing to talk to him, but Jake didn't want to do that because it would be bad for himself and it was he who had put so many responsibilities on Emily to do and so he had to tell them beforehand to talk to her.
After Eva left to go to the restaurant Jake also decided to go to Matthew's house, Matthew was a man who didn't like offices and was almost always at his house, so Jake never had to call beforehand to let him know when he was going.
When Jake arrived the maids soon took him to the living room to wait until they let Matthew know that Jake had arrived, in a few minutes just as he expected who had arrived was Oliver who was now much closer to Matthew and almost spent all his time in this house.
"Hi, Jake, how long, I thought you would come here at the end of last year, so we were waiting for you."
