Final answer:
The overlooked factor in union mergers is called 'human dimensions,' focusing on employee reactions and behaviors during organizational changes. It's crucial for the integration process along with the cultural shifts in the merging entities.
Step-by-step explanation:
The factor often overlooked in union mergers that encompasses how union members are affected and behave as a result of a merger is called human dimensions. Union mergers, like corporate mergers and acquisitions, come with stresses similar to downsizing events. During these processes, it is critical to consider how the organizational culture will change and the additional stress placed on workers as they transition from their connection with the old organization to forming new relationships within the merged entity. This focus on employee reactions is vital for a smooth transition and integration.
The decline in U.S. union membership has been attributed to several factors, including changes in laws and the ironic outcome that the enactment of worker protection laws, strongly supported by unions, has made workers feel less need for union membership. Research shows that human interaction elements, such as workers' relationships with supervisors, and the necessity to balance work-family responsibilities, can significantly affect productivity and employee satisfaction.
