I need help with the following case study:

You are an experienced manager in supply chain (SC) management. Your company is located in Illinois, and you have played a lead role in developing other women to work in this male-dominated field. Your company recently acquired a competitor company in West Virginia. You have been asked to integrate the two companies' supply chain operations. Each location will have an on-site SC director.

You just received a call from the director of human resources with the report that the West Virginia SC director is threatening to leave. Although facts are limited, it seems as though the two SC directors are at odds; each one accusing the other of being rude and exhibiting bullying behavior. You want to better understand what's happening before taking next steps.

You decide to assess the situation starting with a communication focus.

Please help me identify the following:

Please explain six to eight variables that influence effective interpersonal communication and that are pertinent to the scenario; explain these variables in the context of principles, theories, and the employees' environments.

If possible please provide citations so that I can do some follow-up study
