Leaders are often responsible for their own overload. They let themselves be driven by the expectations of their employees – the opposite of leadership.
Personal responsibility works when the leader has a clear idea of leadership. The leader communicates a Coach role built around self-regulation, stabilizes that role, and acts consistently in line with it.
Personal responsibility needs the right conditions. If self-motivation, competence, and sufficient freedom to act are missing, the result is costly underregulation: correction loops, escalations, and, in the end, a leader who takes over again after all.
