Sanitation workers, also referred to as refuse collectors, collect trash from homes and businesses. They either lift the garbage cans themselves or use a hydraulic lift for dumpsters. The work is physically demanding and repetitive. Sometimes they have to lift large heavy objects, such as furniture or large kitchen appliances. They normally work an 8 hour shift that often begins between 5 a.m. and 6 a.m. They usually work regardless of the weather.
