Because of this, packing benches are used to take raw items, such as a box of balloons, and pack them at a specific unit quantity, which are then packed into cartons and labeled accordingly for a customer. In many circumstances this may be more inexpensively done at a distribution center than by a customer or client. Transportation: Arranges and coordinates shipments in and out of the distribution center. Dedicated product departments: Divisions may be based on handling characteristics or storage characteristics, for example, refrigerated and non-refrigerated [meat and produce, frozen, dairy/deli, dry]. Each of these three areas have both shipping and receiving departments as well. Distribution centers also have a variety of supporting departments, including human resources, maintenance/facilities operations, production control, and accounting. Distribution jobs A distribution center typically has a general manager who manages the facility and typically has a number of department managers who report directly to him/her. Most distribution centers divide staff into two categories, direct labor and indirect labor. Direct labor staff execute the distribution processes, while indirect labor staff support the direct labor staff. Each department is in turn composed of supervisors and warehouse workers. The direct labor jobs of a warehouse can include: Unloader - unloads trucks and breaks down pallets as needed, using various pieces of power equipment Receiver - inventories and tags unloaded pallets using a mobile cart computer unit and printer Hauler - transports received pallets with equipment from the receiving dock to the storage racks Putaway driver - puts product into racks with forklift Lumper - helps unload shipments Replenishment driver - pulls product from the racks and places it into the "pick slot" with forklift Order filler - picks product from the "pick slot" by hand and moves with power equipment Loader - wraps the order-filled pallets and loads trucks, using equipment Indirect labor departments and jobs within a warehouse can include: Supervision - floor (process) supervision, indirect labor supervision Human resources - employment office and employee benefits Facilities and housekeeping - maintenance of buildings Inventory management - tracking and placement of product Quality control - inspection and acceptance of incoming and outbound product Asset protection - building security and loss prevention Safety - insurance of safe operating practices Equipment maintenance - electrical, mechanical, and pneumatic maintenance of MHE Operations research - Industrial engineering, process improvement, labor standards Information technology - support of information systems Water Spider - replenishes
