Final answer:
Management likely prefers centralized bargaining for efficiency and consistency across multiple manufacturing facilities making the same product. This aligns with aims for a mechanized work environment and uniformity in production and labor relations.
Step-by-step explanation:
It is true that management would likely prefer centralized bargaining if it had three separate manufacturing facilities (bargaining units), each making the same product. Centralized bargaining provides a uniform approach to negotiations across multiple facilities, which can lead to increased efficiency, lower negotiation costs, and consistent terms of employment across all sites. This preference aligns with the goal of a mechanized work environment and the production of identical products at every location, which is facilitated by the coordination of activities and technology choices that support cost-effectiveness and reduce complexity in management.
