Being a lumper can be hard work. Lumpers are required to lift and carry heavy boxes and containers. But being a lumper is also important work. Lumpers help to keep the flow of goods moving through warehouses and distribution centers, playing a vital role in the supply chain. Lumpers are paid to load and unload trucks, and they often have to do so in difficult or dangerous conditions. While lumper fees can be expensive, the service is crucial to ensuring efficiency with the loading and unloading of goods particularly refrigerated items. Lumpers are typically paid by the hour or via a contracted amount and should provide a lumper receipt for any lumper fees charged and/or lumper payments made.
