Powerful, inspirational leadership can only happen if employees develop an emotional attachment to the boss. The best executives know this. But how do you foster this kind of attachment in a big company where people are scattered all over the world? If you’re like most senior leaders, you try to bridge the distance via email, internal social-media postings, occasional in-person meetings, speeches, and videos. Which are not great for developing relationships. For all kinds of reasons, including the typically bland, scripted nature of a lot of communications, employees tend to tune out official messages.
