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 a campaign by workers seeking better pay, clearer career advancement opportunities, and more input into 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 next step for the newly unionized group will be negotiating their first contract. Their goals include securing improvements in wages and benefits, expanding career opportunities, and ensuring they can raise concerns without fear of retaliation. Collective bargaining is expected to provide them with a protected way to participate in decisions affecting their jobs.
During the organizing process, some workers expressed concerns about management’s actions. These included alleged anti-union tactics intended to discourage unionization efforts and the dismissal of an employee who was openly supportive of forming a union.
Discovery World staff play an important role in delivering interactive exhibits and educational programs that serve families, students, and visitors throughout Milwaukee.
IAM Midwest Territory General Vice President Sam Cicinelli stated: “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 in North America including aerospace, defense, airlines, shipbuilding, railroad transit systems as well as healthcare and automotive sectors.
