There are many difficult aspects to leadership: from having the best plan, to hiring the best talent, to putting in excellent standard operating procedures, to making decisions around products, pricing, promotion, and productivity measures, and so forth. Yet, to me, one of the toughest decisions a leader must make is letting someone go. In my decades of work with many organizations, a defining trait of the best leaders is the ability to make the uncomfortable decision on when to move someone out of a position and most likely out of the organization. There are very few leaders who don’t struggle with this.
