Lumper
A third-party worker hired to load or unload freight at warehouses and distribution centers, common in the grocery and retail industries.
A lumper is a third-party laborer who is hired to physically load or unload freight from trailers at warehouses, distribution centers, and manufacturing facilities. The term dates back to the early days of shipping, when dockworkers would 'lump' (move in bulk) cargo from ships. In modern trucking, lumper services are most prevalent in the grocery, food and beverage, and retail industries, where receiving facilities often require the use of lumpers rather than their own warehouse staff or the truck driver.
Lumper fees typically range from $100 to $500 per load, depending on the complexity of the unload, the type of freight, the number of pallets or cases, and the geographic region. Some facilities charge flat fees, while others base the cost on labor hours or the number of units handled. For a driver delivering to multiple stops, lumper fees can add up quickly and significantly impact the profitability of a load.
The question of who pays for lumper services is a common point of contention. Federal law (49 USC §14103) prohibits carriers from being coerced into paying for lumper services — if a receiver requires lumpers, they must allow the driver to use their own helpers or pay the lumper fee themselves. In practice, however, the cost is typically borne by the carrier and passed through to the shipper or factored into freight rates. Many carriers require receipts for lumper fees for reimbursement and accounting purposes.
Lumper services can actually benefit carriers in certain situations. Rather than having a highly paid CDL driver spend hours unloading cases of product by hand, a lumper crew can complete the task faster while the driver rests or handles paperwork. This is especially valuable for drivers on tight schedules or approaching their hours-of-service limits. Some large retailers, such as Walmart and Kroger, have moved toward in-house unloading or automated systems to reduce reliance on lumper services.
