We are living in an era of communication 2.0, and that changes the nature and responsibilities of the human resources function. More channels for communication mean more ways to engage employees—and more ways for disengaged employees to express their discontent inside and outside the company. Engaging employees should be a continual and thoughtful process that encompasses internal social media and the tactful communication of ongoing change. In the end, your job is not about the new tools you use, however: it’s about the timeless virtues of leadership and talent development. No matter how much the technology sparkles, it can never fix a broken culture or a bad leader.
