It was year 2011-12 when I ran series of workshops for this Indian organization for their middle and senior executives at multiple locations. HR director used to pick up employees who are high potential but with some challenges. My job was to heal them and coach them so that they can be integrated in the company culture. She told me about an executive, who, they knew as very high performer but could not live with him. His anger and disobedience was much beyond their tolerance but his skills and knowledge was rare and unique to the company, hence they could not let him go.
