Chicago Museum of Science and Industry Workers Ratify First Union Contract

Chris Garlock | Published on 12/4/2025

Griffin Museum of Science and Industry (MSI) workers, represented by AFSCME Council 31, have successfully ratified their first union contract.


Staff at the Chicago institution first formed MSI Workers United in 2023 and faced strong headwinds from an aggressive union-busting campaign. Nevertheless, members persevered and ratified their new agreement with a near unanimous vote right before Thanksgiving. The agreement includes major wins like wage floor increases, holiday pay, establishment of a joint labor-management committee, a grievance procedure and more.

 

“No longer can management just act on a whim with no recourse for workers,” said Council 31 Public Affairs Director Anders Lindall. “Overall, I would say that it’s a really strong agreement that lays the foundation for employees to transform MSI into an even better workplace going forward.”
