Refer to Case 2.1.As vice president of human resources,Cynthia wants to communicate the changes in benefits to the employees clearly with an opportunity for response.Her best communication tool for this would be​

A) ​the grapevine.
B) ​the horizontal communication channel.
C) ​a memo from her department.
D) ​e-mail with a way for employees to ask questions.

Email with a way for employees to ask questions would be the best tool for Cynthia to communicate the changes in benefits to the employees clearly, as it allows for immediate and direct communication with the employees, and also provides them with a way to ask any questions or raise concerns they may have. This would enable Cynthia to address the small group of employees who reacted negatively and address their concerns directly. The other options, such as the grapevine or a memo from her department, may not provide the necessary opportunity for feedback and communication between Cynthia and the employees. The horizontal communication channel may not be as effective in this situation as it involves communication between coworkers at the same level, rather than a direct communication between management and employees.
