What is the proper term or phrase used to discribe employee-managment working groups?

I worked in a factory in Maine years ago, and the management / excecs hired this firm, which came to the factory, and organized us low-level workers into teams, one or two from different departments. Then we were guided as to how to evaluate our working environments and practices, and then submit these observations to executives for implementation. (sorry, my spell checking machine is not working ...??!! ) Any help in this regard will be greatly appreciated. Thanks so much.
