A cleaner works to keep an organization tidy and orderly by taking stock of cleaning supplies and completing small cleaning jobs throughout the day like emptying trash cans, washing windows and scrubbing any dirty areas. They’re often given a certain set of tasks to complete before their shift and must have them finished by the end of the day. Cleaners are responsible for the safety of patrons or office working by ensuring areas and properly sanitized and cleaning up any spills or messes that may harm customers or other employees.
