what responsibilities does a stockier at Walmart have?

Walmart is one of the world's most valuable companies in the United States. I believe that a stock person would be responsible for obviously stocking, assisting with inventory and customer service.

At Walmart, I believe a stock person could assist in customer service by providing service to the customer during the process of a purchase - such as locating a particular product.
