Hundreds of dealers and Transport Worker Union members gathered in front Caesars Palace Thursday afternoon to show their support for the casino’s dealers during prolonged union contract negotiations. Tourists weaved in and out of the sea of TWU members, dealers and supporters as they tried to make their way down Las Vegas Boulevard. Demonstrators, dressed uniformly in red union T-shirts, held signs reading “Contract now” and “Give Caesars dealers a fair deal.” Their chant: Two years is too long.
