The Problem
Every year, millions of people are promoted into leadership roles with a title, a handshake, and an assumption that they’ll figure it out. Most do — eventually. But the cost of that learning curve is significant: disengaged teams, preventable turnover, and leaders who burn out before they find their footing.
