Having a mentor has always helped with professional development and career advancement, but in today’s complex workplace, one mentor alone often won’t do. To spark innovation and ideation, employees often require information from a number of areas in real time. That’s why there is a need for us to have multiple mentors with expertise in various domains. The good news is the rapid expansion of social media inside and outside companies has made it possible for aspiring leaders to hone their craft from the very best experts in many domains via the internet or knowledge management (KM) systems. They can become your virtual mentors.
