Overview
A janitor, also known as a janny, custodian, porter, cleanser, cleaner or caretaker, is a person who cleans and maintains buildings. In some cases, they will also carry out maintenance and security duties. A similar position, but usually with more managerial duties and not including cleaning, is occupied by building superintendents in the United States and Canada and by site managers in schools in the United Kingdom. Cleaning is one of the most commonly outsourced services.
Etymology
The word janitor derives from the Latin "ianitor", meaning doorkeeper or porter, itself from "ianua", meaning door, entrance or gate. This derives from "Janus", the Roman god of doors, gates and portals.
Its first recorded use meaning "caretaker of a building, man employed to see that rooms are kept clean" was in 1708.

Most of the work performed by janitors and building cleaners is indoors. Office buildings are usually cleaned when they are vacant, so most of the office janitorial staff work during the evening. The work can be physically taxing and sometimes dirty and unpleasant.
