I am considering your questions carefully, Marcus.

Easy question first. Employees often follow a leader's example, good and bad.

Those who look to leaders to set the tone must have a strong character to proceed and do the right thing if the leader is not setting a good example. If you consider the (true) story in the post, Claire proceeded with what she needed to do despite all of the bad examples set by leaders in front of her. You will have those outliers. You will also have people who do the wrong thing even if the leader is setting a good example.

Next. I think that the willingness to be accountable is inherent in the role of leader. Whether the person embraces it or not separates the leaders-in-title from real leaders.

Thank you for commenting and asking questions.
