In regards to the bolded part, I think you are missing a detail. All great managers (any industry) are at minimum, above average leaders. Leadership is not about being liked, as you astutely point out, but it is always penultimately about respect, and excellent communication. No one can be a good leader without those two skills with the ability to give and receive…Those two skills are two way streets. Usually those two skills coincide with some level of affinity. If an individual really dislikes another, it’s almost impossible to hear what they mean. A leader delivers a message in a way that is meaningful to the receiver and listens with empathy to receive the message in the intended way. No one can do that with a certain level of personal dislike.
on the underlined, that’s my fear too. The executive micromanager too overwhelmed to let things go and can’t lead anymore or execute. It’s a scary thought.
