NEW YORK -- Wal-Mart will cut about 11,200 jobs at Sam's Club warehouses as it turns over the task of in-store product demonstrations to an outside marketing company.

The move is an effort to improve sales at Sam's Club and comes on top of a decision to close 10 underperforming warehouse locations, which cost 1,500 jobs.

The cuts represent about 10 percent of the warehouse club operator's 110,000 staffers across its 600 stores. That includes 10,000 workers, mostly part-timers, who offer food samples and showcase products to customers. The company also eliminated 1,200 workers who recruit new members.

Shopper Events, based in Rogers, Ark., currently works with Wal-Mart's namesake stores on in-store demonstrations. Sam's Club is looking to the company to improve sampling in areas such as electronics, personal wellness products and food items.
