Janitor

A janitor (American English, Scottish English), custodian (British English), janitress (female), cleaner or caretaker is a person who cleans and maintains buildings such as hospitals, schools and residential accommodation. Janitors' primary responsibility is as a cleaner. 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. Cleaning is one of the most commonly outsourced services.
