NEW YORK (AP) — Walmart, the world's largest private employer, is boosting its starting salary for U.S. workers to $11 an hour and handing out one-time cash bonuses. The company cited tax legislation that will help it save money, but the moves also reflect the tight labor market in which employers are competing for workers. The world's largest retailer said the moves, which also include expanded parental leave benefits, will affect more than a million hourly workers in the U.S. Employees previously started at $9 an hour, with a bump up to $10 after completing a training program.
