Warehouse Clerks assist with shipments coming in and out of warehouses. They move incoming material to the proper locations within the facility and retrieve necessary items for outgoing shipments. Their efforts are essential to proper storage within the warehouse and accurate order fulfillment to customers. Retail and manufacturing supply chains depend on Warehouse Clerks to keep merchandise flowing through the system. Depending on the size and set-up of the facility, Warehouse Clerks may work independently, as part of a small group or as assistants to a large team. Warehouse Clerks spend much of their time on their feet and need to be able to bend and lift. Because of the physical nature of their job, Warehouse Clerks should be in good shape and possess stamina. Hours can be long, especially in busy seasons.
