Wynn Las Vegas was the only casino where dealers shared 15 percent of their tips with people who dealers argued were supervisors. The policy was implemented in 2006 because Wynn’s high-end customers tended to tip more than at other resorts. As a result, dealers were taking home more than their bosses. The company reversed its policy in November 2018, restoring floor supervisor positions and ending the share policy. But now dealers want back pay from lost tips. The dealers hope to recoup as much as $50 million.
