About Joker Rainbows
Other than Station, Las Vegas Sands had been the other largest non-union holdout in Las Vegas for many years. But when the Venetian-Palazzo was sold to Apollo Global Management in 2021, the firm had no issues with Culinary and ratified the property’s first-ever deal with the union in 2024.
The animosity between the sides has become political over the years. Station is owned and operated by the Fertitta family, who have been prominent Republican donors for many years. Culinary is a largely Democratic organisation that typically supports and endorses left-leaning candidates.
Last month, US President Donald Trump made an impromptu visit to Las Vegas, hosting a rally at Red Rock. Trump called the Fertittas a “beautiful family” during his remarks. Culinary, meanwhile, denounced the event and the Fertittas’ support of Trump and Nevada’s Republican Governor Joe Lombardo.
