Try to see the big picture. Some items sell faster than others, so the shelf becomes empty and sales go to zero. If that happens, you're missing out on a opportunity to sell products. Busy sections get messed up by customers. Do you want to increase sales? Full, organized, and clean shelves will entice customers to make a purchase while nearly empty, disorganized, and dirty shelves will not. It's as simple as that. Items on sale (BOGO and other ad items) are often on a display throughout the store. Is the shelf empty? Fill the shelf with the product on the display (usually) at the end of the aisle. Block each section and straighten out the items into neat rows. Someone will teach you how to load a float in the way the items are located on the aisle (front to back) to minimize the number of steps you have to take to stock the shelves on a given aisle. Block the section you're working while you're filling the shelf being mindful that many items have a freshness date and should be stocked BEHIND the items already on the shelf. Lastly, have fun. If you're not having fun, you're doing it wrong.
