If possible, avoid talking about a personal relationship. While the question might bring personal relationships to mind first, the interviewer wants to hear about your professional abilities. If you cannot think of an example involving an employee or colleague, reframe the question to explain how your effective communication strengthened your relationship with a whole team or another agency.

"A social worker on my team was very enthusiastic and hard-working but sometimes seemed disconnected in team meetings. After a meeting in which she seemed particularly distant, I asked to speak with her. I was careful not to make assumptions about her demeanor and asked open-ended questions. I learned that she had been under the impression that her contributions were not valued because she was too new to the job. I explained that she was an equal member of the team and that her more seasoned colleagues could learn from her. I set a clear expectation that she participate from that point forward, which she did with great success."
