Philip K. Dick short story about a man who goes to work via a tunnel

Question

I'm looking for the title of a Philip K. Dick short story about a man who goes to work via a tunnel. His company allowed him to, so he can get to work by just walking and doesn't have to be stuck in traffic. And he has to report anything weird to his company, but he doesn't... he also sees people inside, tiny people, and can communicate with them.

Answer 1

Could this be Prominent Author by Philip K. Dick?

This review mentions the 'small people' that he encounters on his trip through the tunnel.

Henry Ellis is in a tunnel. The commute is actually not instantenous. He has to walk through this tunnel for five steps. The device—the Juffi-scuttler—uses travel through the fourth dimension. The Juffi-scuttler was developed to solve the growing problem of the commute. As more people moved to suburbs, the commutes became longer and more odious. The fourth dimension allowed an infinite number of Jiffi-scuttlers. Any family that could afford the 1000 credits could have one. The only downside was that it was fixed. Each end of the Jiffi-scuttler was stuck. Not surprisingly most people used their Jiffi-scuttler to travel from home to work. While taking his time walking through the tunnel, Henry saw three tiny people, each the size of insects. They looked up at Henry with shock. They wore sandals and brown robes and looked to him entirely alien. Henry did not want to be late for work, so he quickly exited the tunnel and arrived in New York.

At the end of the day, Henry talks to Patrick Miller from the research office of Terran Development. He was the one who arranged for Henry to try out the Jiffi-scuttler to test for any problems before the machines would be put on the mass market. He asks for details about what goes on in the tunnel and how the transportation is actually effected. Unable to articulate his questions and concerns, he prepares to go home. Going back into the Jiffi-scuttler, Henry sees another group of people, wearing different clothing and slightly taller (six inches). They look up in amazement at Henry.

The next morning, Henry goes back to work and sees the small people again. This time they were prepared for his arrival. They are also writing down something on a very small piece of paper. He takes the paper. That day, he asks a colleague in the Research Labs if he can borrow a photo microscope. Using it, he takes a closer look at the paper and confirms that the small people were writing something on it. He uses a translation machine to decode the writing, which turns out to be a series of questions. He spends the day answering them and running them back through the translator. He gives them the answers on the way home.
