I have a direct report that is typically a great associate. This individual puts our clients first and generally stays on task and works very hard every day. I have been out of the office twice the last two months for business trips. Upon my return I have had other associates approach me about this individuals behavior. Their feedback was that he was short with them, argumentative and sometimes not helpful. It appears that this behavior only exists when I am out of the office. Do I need to call and check in on this person while I am traveling? Do you have suggestions on another approach to handling this behavior?
