A facilities worker who cleans and maintains buildings, schools, offices, and public spaces.
What janitors do
Janitors sweep, mop, and vacuum floors, sanitize restrooms, empty waste, restock supplies, and handle light maintenance such as changing bulbs and clearing minor clogs. They follow building schedules to clean offices and classrooms outside business hours.
Training path
Most learn on the job, with senior janitors mentoring new hires on equipment and chemical handling. Voluntary certifications from the IICRC, ISSA Cleaning Industry Management Standard, or OSHA HAZWOPER add credibility for commercial roles.
Work setting
Janitorial work happens in schools, office towers, hospitals, factories, and government buildings. Many janitors work overnight shifts so cleaning does not interrupt occupants, though daytime crews handle public spaces and high-traffic areas.
