IUOE is the 10th largest union in the AFL-CIO, with 400,000 active members in 123 local unions throughout the US and Canada. 

Per the agreement, the parties will take a neutral approach to organise campaigns that will enable every Tropicana Las Vegas employee to make an informed decision regarding their union representation. 

Soo Kim, Bally's Chairman, said: "Bally's employees are our most valuable asset, and we have worked hard to ensure that they maintain an unimpeded right to select their representation. 

“We have an established track record of building positive relationships with organised labour and look forward to continuing to foster our relationship with IUOE.” 

Jose Soto, Organising Director of IUOE Local 501, added: "Bally's and IUOE are aligned in our efforts to advance employee representation locally and at the national level." 

"As a result of the commitment and integrity demonstrated by Mr Kim and his team, we've developed a strong relationship with Bally's that we are confident will benefit the company's workforce for many years to come." 

Elsewhere, Bally's recently entered a multi-project labour agreement with the Chicago & Cook County Building & Construction Trades Council and the AFL-CIO Building and Construction Trades Department to facilitate the construction of its flagship Bally's Chicago casino. 

And this month, Bally’s appointed Kim Barker Lee as its new EVP and Chief Legal Officer – an appointment the operator says aligns with its continued global growth and operational diversification push.
