Test operators work in a variety of settings, including factories, laboratories, and offices. They may work in clean rooms, where they must wear special clothing to avoid contaminating the products they are testing. They may also work in areas that are exposed to noise, dust, and other potential hazards.
Test operators typically work a standard 40-hour week, but they may be required to work overtime to meet deadlines or to complete projects. Some test operators may be on call 24 hours a day to respond to emergencies.
