Wal-Mart is under assault from every direction again. In most papers these days, unions are attacking the mega store for treating its employees very poorly. So, is it deserved? The average Wal-Mart worker earns $9 and some change an hour. About half of the workers have health care. On the other hand, workers at Sam’s Club, which is owned by Wal-Mart, earn about $12 an hour. And Costco Wholesale, workers get $16 an hour on average and almost all employees have health care. Consumers are calling on Wal-Mart to pay higher wages and offer more health coverage. Clark thinks it’s not something Wal-Mart should be forced to do. The market will determine what Wal-Mart does. The company has very high turnover and many disgruntled employees. At some point, Wal-Mart will have to do something about that if it realizes it’s hurting the business. But people are not being forced to work there. They can find jobs that offer better benefits elsewhere if they want.
