According to persuasive communication research, getting an employee to accept a new policy is more easily done when:

A) you only give the employee information that supports the policy.
B) the information is written down rather than discussed orally.
C) the employee believes that you are credible and have expertise on the topic.
D) the employee is publicly committed to an opposing attitude.
E) both 'A' and 'C' occur.

According to persuasive communication research, credibility and expertise of the communicator greatly influence the acceptance of the message. Therefore, if the employee perceives the communicator as credible and knowledgeable, they are more likely to be persuaded to accept the new policy. Option A is incorrect because only presenting information that supports the policy is a form of biased communication and can be seen as manipulative or lacking in transparency. Option B is incorrect because the communication channel (oral vs. written) does not have a significant impact on persuasion. Option D is incorrect because public commitment to opposing attitude usually makes the person resistant to change.
