Walmart is expanding its Associate-to-Driver training program, offering employees at more than 400 stores, distribution centers and other locations a chance to earn six figures driving trucks for its private fleet. Through the program, the company fully covers the cost of obtaining a commercial driver’s license and pays workers during the 12-week training to become a driver. Walmart offers long-haul drivers starting salaries as high as $110,000. A pilot of the program — offered last year to supply chain associates in Dover, Delaware, and Sacramento, California — trained 56 new truck drivers, according to Walmart. Another 252 employees plan to become drivers through the program this year.
