A trustful environment helps a team to focus its energy on the goal. Uncertainty and skepticism about the team members’ genuine intentions are one of the factors that can distract the focus. That creates unnecessary questions, gives a lot of food for interpretation and inference.
We do not need to lose the groups valuable energy in climbing the ladder of inference.
Clarity on why do we work with the team, how do we work and what do we want to achieve, helps. The dialogue about the plans of the team members increases the confidence level of the team.

What to do? Where to start?

As a leader, first, share your intention with your team. And then listen what others have to say.

Good leaders have good teams; great leaders have great teams.
