When the CEO of a company I worked for was in corporate headquarters, he had a habit of walking around the office every day. He did this once in the morning and once in the afternoon. This gave the employees the feeling that their Leader was not isolated in some ivory tower but with them on the front line.
When he wasn’t at corporate headquarters, he was often at one of our plants doing exactly the same thing.
These walkabouts kept the lines of communication open with the front line employees, who were able to share with our CEO real company issues they were having that were not being timely addressed by their immediate supervisors. In this way, the CEO acted in the capacity of a trouble shooter, which would not have been possible if he/she were locked away in some executive office.
