A Lesson from my Perspectives on Leadership course:
Teams perform better when everybody feels safe to share ideas, concerns, questions, and mistakes without fear of judgement or embarrassment. Good leaders promote this type of environment by making every task into a learning opportunity, by admitting their own fallacies, and by promoting curiosity. This will allow employees to develop out-of-the-box thoughts and solve interesting problems.
We can all learn something about interpersonal relationships from this model.
