LAS VEGAS (AP) — A federal appeals court has upheld a judge’s ruling in Nevada requiring Station Casinos’ Red Rock Casino to bargain with the culinary and Bartenders unions. The ruling by the 9th Circuit Court of Appeals is a victory for the union. It’s part of a yearslong fight to unionize about 1,350 employees at the Las Vegas-based casino company it accuses of refusing to negotiate in good faith. Union leaders accused Red Rock of undercutting a 2019 union election by enhancing health benefits and retirement contributions just days before the vote. The appellate panel agreed with the U.S. judge who cited a “landmark violation” of federal labor law in July.
