Janitor
A janitor (American English, Scottish English), janitress (female), custodian, porter, 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 (and occasionally in Canada). Cleaning is one of the most commonly outsourced services.
