Do You Need Extra People to Engage in Deep Work?

If cal newport says, you knowim going to close the door in my office, i'm not going to answer my phone. But if some one needs to get in touch with you in an emergency, that person is probably going to reach an assistant of yours. So i don't think you need actual extra people involved to make space for deep work,. but i do think it almost always requires some effort and reconfiguration of people's expectations on how and when they can reach you.
