Etymology

The word ''janitor'' derives from the
Latin Latin ( or ) is a classical language belonging to the Italic languages, Italic branch of the Indo-European languages. Latin was originally spoken by the Latins (Italic tribe), Latins in Latium (now known as Lazio), the lower Tiber area aroun ...
''"ianitor"'', meaning doorkeeper or porter, itself from "''ianua"'', meaning door, entrance or gate. Its first recorded use meaning "caretaker of a building, man employed to see that rooms are kept clean" was in 1708.

population living in the United States work in the cleaning industry (and growing at a rate of 1/2% to 1/3% per year). In addition to this population offering an abundant source of inexpensive labor, janitorial work is mostly undertaken at night, making it an appealing option for janitorial companies to employ illegal workers seeking clandestine employment. In the Netherlands, the number of cleaning companies grew from 5,000 in 2003 to 8,000 in 2008.


Pay scale

According to the U.S. Bureau of Labor Statistics, in 2023 the median pay of a janitor working in the US was $16.84 per hour.


Outsourcing

Cleaning is one of the most commonly outsourced services. Some of the reasons for this include: * Basic cleaning tasks are standardised, with little variation among different enterprises. * The nature of the job and required standard of performance can be clearly defined and specified in a contract, unlike more technical or professional jobs for which such specification is harder to develop. *Some organizations prefer to outsource work unrelated to their core business in order to save additional salaries and benefits required to manage the work. * Some organizations may feel uncomfortable dealing with labour relations related to low wage employees; by outsourcing, these labor relations issues are transferred to a contractor whose staff are comfortable and experienced in dealing with these issues, and their approach can benefit from
economies of scale In microeconomics, economies of scale are the cost advantages that enterprises obtain due to their scale of operation, and are typically measured by the amount of Productivity, output produced per unit of cost (production cost). A decrease in ...
. * If a janitor is unavailable due to sickness or leave, a contractor which employs many janitors can easily assign a substitute. A small organisation which employs one or a few janitors directly will have much more trouble with this.

Office cleaning

Office cleaning staff perform many of the same duties as janitors. However the tasks are divided among different members. Additional tasks can include: * watering plants (pruning as well) * cleaning sinks, refrigerators, microwave ovens, toasters in office kitchens, and clearing recycling / garbage bins * dusting furniture, computer equipment (monitors and desk area, but excluding keyboards), and tables

Most of the work performed by janitors and building cleaners is indoors.
