Approximately 56 employees at Discovery World, a science museum in Milwaukee, have voted to join the International Association of Machinists and Aerospace Workers (IAM Union). The decision follows an organizing campaign focused on securing fair compensation, clearer career advancement opportunities, and increased input in workplace decisions.
Adante Balke, IAM Midwest Territory Special Representative, commented on the outcome: “Congratulations to the Discovery World workers on making their voices heard and officially winning their union election. These dedicated employees are coming together to demand respect, fair wages, better benefits, and greater transparency in promotions and hiring. By standing united, they are now preparing to bargain collectively for a stronger future.”
The newly formed bargaining unit will begin negotiating its first contract with management. Their goals include improvements in pay and benefits as well as safeguards that allow staff to voice concerns without fear of retaliation.
During the unionization effort, workers reported issues with management’s approach. They alleged that anti-union tactics were used to discourage participation in the organizing process and noted the dismissal of an employee who was a vocal supporter of unionization.
Discovery World staff play a key role in operating interactive exhibits and educational programs for families and visitors. Their work is seen as central to maintaining the museum’s reputation as a leading destination for learning experiences.
IAM Midwest Territory General Vice President Sam Cicinelli expressed appreciation for local government officials who supported the workers’ efforts: “The IAM Union is proud to welcome these workers into the IAM family. We would like to give special thanks to Milwaukee Common Council Members Alderman Alex Brower, Alderwoman Marina Dimitrijevic, Alderperson JoCasta Zamarripa, and Alderman Robert J. Bauman for standing in solidarity with Discovery World workers and supporting their right to organize. We stand ready to support them as they move toward a strong first contract that reflects their value, protects their rights, and ensures Discovery World remains a place where workers and the community can thrive together.”
The IAM Union represents around 600,000 active and retired members across various industries including aerospace, defense, healthcare, transportation sectors such as airlines and railroads throughout North America.
