The ability for an hr manager to oversee a diverse group of employees and to manage the hr office is part of . a. change mastery b. human resources mastery c. business mastery d. personal credibility

I would think that the answer would he the second option mainly because if the head boss were to oversee groups and other members, I would then think that of course, he would need to master any resources that would be high quality in order to help others.

Do you have an a b c d ? ? respond ; )
