The NLRB rejected a request from Las Vegas-based Station Casinos to stop the unionization of its Green Valley Ranch resort. Workers voted in favor of representation by Culinary Local 226 and Bartenders Local 165 in November 2017, but management fought the election. The same company is challenging the April 2018 election at another one of its resorts called Palms. The casino chain did not tell Las Vegas Review-Journal reporters on what basis they are challenging the elections.
