Teamsters will represent more than 100 Black Hawk Casino workers

In a press release, Teamsters confirmed that a total of 110 casino workers at Black Hawk Casino chose to unionize via a card-check process.

Organizing with Teamsters Local 455 marks the first time in the history of Colorado casino workers have unionized.

Through this milestone achievement, the workers will benefit from wage increases, improved benefits, and better working conditions, among other amenities.

Notably, the group of workers includes slot attendants, slot technicians, cashiers, cooks, bartenders, servers, housekeeping and maintenance staff.

Dean Modecker, Teamsters Local 455's Secretary-Treasurer, was similarly excited.

He acknowledged that the unionization effort by Black Hawk Casino workers marks a major moment in the history of Colorado.

"Our brothers and sisters at Local 455 are excited to welcome the newest bargaining unit to our family. And we're ready to represent and protect them in the fight for a fair first contract," Modecker said in conclusion.

Tommy Blitsch, the Director of the Teamsters Convention, Trade Show and Casino Division, added: "The workers at Black Hawk Casino came together to secure a stronger voice on the job, and they've made history in the process."

He spoke about the outstanding accomplishment by the workers that can now unlock benefits through Teamsters representation.
