Housekeeper Environmental Services
No special education is required for most janitorial or cleaning jobs, but beginners should know simple arithmetic and be able to follow instructions. Maids and housekeeping cleaners perform any combination of light cleaning duties to keep private households or commercial establishments such as hotels, restaurants, hospitals, and nursing homes clean and orderly. Most building cleaners learn their skills on the job. Beginners usually work with an experienced cleaner, doing routine cleaning. As they gain more experience, they are assigned more complicated tasks.
Maids and housekeepers held about 1.4 million jobs. Hospitals, nursing homes, and other residential care facilities employ large numbers. Although cleaning jobs can be found in all cities and towns, most are located in highly populated areas where there are many office buildings, schools, apartment houses, nursing homes, and hospitals.
Overall employment of building cleaning workers is expected to grow as fast as average for all occupations through 2014, as more office complexes, apartment houses, schools, factories, hospitals, and other buildings requiring cleaning are built to accommodate a growing population and economy.
