It continues to puzzle us how senior leaders in organizations expect things to go well for lower level leaders who are less trained than they need to be. It's a naive expectation that tenure, education or previous performance as an employee prepares people to be good leaders.
The Catch-22 is that senior leaders only know what a well-trained leader is to the extent they are well-trained.
I would not argue that skillful leadership automatically occurs when someone is promoted into a leadership position, or assumes a leadership position because they are a founder or owner. Some people come into leadership positions with personal traits and habits that support good leadership, but good leadership is a specific craft that one explicitly learns and practices.
