Bally’s Black Hawk Casinos Mark Historic Unionization as Workers Join Teamsters Local 455

The employees at Bally’s three Black Hawk, Colorado casinos voted through a card-check process to join Teamsters Local 455, and this development establishes the first instance of casino workers unionizing anywhere in the state while covering 110 individuals who work as bartenders, cashiers, cooks, maintenance technicians, slot attendants, and slot technicians across the East, North, and West locations.

Details of the Card-Check Process and Worker Coverage

Card-check voting allowed employees to demonstrate support by signing authorization cards, and the approach streamlined recognition without a traditional secret-ballot election, while the resulting bargaining unit encompasses the full range of listed positions at all three Bally’s properties in Black Hawk, and observers note that this structure brings together diverse operational roles under one local union representation for the first time in Colorado gaming history.

Background on the Neutrality Agreement

Bally’s and the Teamsters reached a neutrality agreement in November 2025, and that pact set the framework under which the subsequent card-check vote took place, while the agreement outlined mutual commitments that facilitated the organizing effort and enabled the workers to complete the process in an environment free from active opposition by management.

Scope of Representation and Next Steps

Once certified, the new bargaining unit gains the ability to negotiate contracts covering wages, benefits, and working conditions for the 110 employees, and the Teamsters Local 455 now holds formal responsibility for representing these workers in future discussions with Bally’s management, whereas the union previously had no casino membership base inside Colorado prior to this vote.

Industry reports from casino.org confirm the vote outcome and the composition of the unit, and additional context from labor data maintained by the U.S. Department of Labor shows how card-check procedures have been used in similar service-sector organizing campaigns across multiple states.

Context Within Colorado Gaming Operations

Black Hawk remains one of Colorado’s primary gaming markets, and the three Bally’s properties operate alongside other casinos in the area, while the successful unionization vote at these specific sites introduces collective bargaining into a sector that had previously operated without union contracts for frontline staff anywhere in the state.

Those who have tracked gaming labor trends note that the inclusion of both gaming-floor roles such as slot technicians and support positions such as cooks and cashiers creates a broad unit that reflects the full operational needs of the casinos, and the neutrality agreement reached months earlier helped maintain focus on the vote itself rather than prolonged disputes.

Conclusion

The card-check vote at Bally’s East, North, and West casinos in Black Hawk therefore stands as the initial unionization of casino workers in Colorado, and the 110 employees now represented by Teamsters Local 455 enter a new phase of labor relations that stems directly from the November 2025 neutrality agreement and the subsequent organizing effort.
