One of the building blocks of trust is demonstrating and living integrity as a leader.
And here are at least three behaviors we can intentionally show at any moment in time:
1) Call the things as they are, tell the truth and check whether your reality is the same as the others. Show honesty.
2) Equally apply the agreements to everyone, whatever they are. Bring high attention to fairness.
3) Communicate clearly and leave the right impression, as you have originally planned to do. Live authenticity.
All those three steps will lead to an integer behavior. This behavior is one of the growing seeds of a plant full of trust.
Good leaders have good teams; great leaders have great teams.
