What historic step was taken at the 15th Convention related to labor-management relations?

The establishment of the Council on Industrial Relations at the 15th Convention represents a significant historic step in labor-management relations. This initiative was aimed at improving communication and resolving disputes between management and labor. The Council was designed to facilitate dialogue, ensuring both parties could address their concerns and work towards mutual agreements in a structured manner. This was a crucial advancement in promoting fair labor practices and improving workplace conditions, influencing how labor-management relations would evolve in the future.

The other options, while relevant to various aspects of labor relations, do not reflect the same level of impact as the formation of the Council. For example, creating an advisory board or standardizing job descriptions may contribute to organizational clarity and efficiency, but they do not address the fundamental dynamics of labor relations in the same proactive way. Implementation of wage increases is an outcome rather than an establishment of a framework or structure to foster ongoing dialogue and negotiations between labor and management.
