When you fail to engage with your people. A leader cannot spend all thier days sitting in the throne in the castle with not clue what is happening to the people in the kingdom.
Also when a leader has no clue about the work being done and does not look beyond the numbers. The people are the drivers behind the paper and the process. People are cricitial in the situation and should be given a higher pecking order.
I learned from some great leaders this simple thing; you have to let people know that they matter and that you care.
