response: That's true! A similar job is being a building superintendent. They do more managerial work.
history: I used to work as a janitor at an office building.  I worked at night so it was quiet and sort of nice. Oh did you?  I understand that sometimes janitors do security and mantenance duties. Yeah, I was also told to look for anything out of the ordinary as well. Oh.  Sometimes it's unpleasant, and it's physically demanding work! Yeah it is.  Oh do you know anything about building superintendants?
knowledge: A similar position, but usually with more managerial duties and not including cleaning, is occupied by building superintendents in the United States.
