Marshall Goldsmith, who coaches Fortune 100 CEOs, says leaders are often blind to how they're playing favorites.
Favoritism can kill innovation, problem-solving and effective decision-making. It can also lead to a talent drain since one of the biggest drivers of motivation is contribution. When an employee feels s/he can't contribute, morale goes down and the search for a new job begins.
Goldsmith discusses how leaders can avoid this problem, even when they're in denial.
