Labor seems to be the largest segment of complaints against Walmart. The low-cost retail giant is one of the largest employers in the world.
Complaints about Walmart's labor practices center on its policy of discouraging union formation and participation. Low wages and the lack of full-time hours cause further problems. Walmart has faced past legal actions for gender and racial discrimination. News reports suggest these problems have led to high labor turnover. As a result, customer service complaints have increased. Empty shelves, not enough cashiering staff as well as a lack of knowledgeable associates have also turned customers away from the retailer.
