Protesting outside of the Palms Casino Resort is expected to take place this week in an attempt by Nevada’s largest labor group to unionize workers.

Culinary Workers Union Local 226, which represents 57,000 Las Vegas casino workers, said the protest on Friday will start at 5 p.m. at the off-Strip property. They expect support from workers and the community to number 1,000, as reported by the Associated Press.

According to the union, workers have been attempting to organize since last year. Petitions delivered to management by workers seeking a union vote without interference have been rejected by the company.

Palms CEO Todd Greenberg was delivered a petition in June 2015 by members of the Palms Organizing Committee, many of whom work in beverage and food departments, asking that management remain neutral and allow workers to decide for themselves about unionization. The request was denied by Greenberg, according to a Culinary Workers Union Local 226 press release.

A few months later, workers were joined by local faith leaders as a second petition was delivered. The petition, signed by a majority of their coworkers, requested that the resort agree to a fair process allowing workers to opt for unionization free from management interference, harassment, intimidations, litigation, and bullying. However, a memo (pdf), dated August 17, was delivered to hotel staff at the Palms stating that hundreds of jobs in beverage and food departments at the casino resort would be outsourced on November 2, 2015. Workers were offered severance by the company and management told workers that they could “apply for other open positions at Palms or with Socexo.”

According to the release, Palms’ plan to subcontract food and beverage jobs to Sodexo would affect more than 220 Palms workers who hold positions in the coffee shop, buffet, main kitchen and bakery.

TPG Capital and Leonard Green & Partners, private equity firms with $67 billion and $15 billion in assets, respectively, have owned the Palms since 2011.

Currently, there are 12 property’s listed on the union’s website as having active labor disputes; the Trump Hotel Las Vegas, Palms, Aliante, and nine Station Casinos.
