In a situation like the one you describe, you must act proactively. First, you must identify and develop potential leaders within the team, providing them with opportunities to grow and explore their leadership competencies. Setting clear expectations and effectively communicating goals and roles within the team can help foster an environment of collaboration and accountability. It is also prudent that you seek external advice or leadership training to strengthen leadership skills within the team and improve its overall performance.
When the sentence begins with "my team..." there are only two options: Either you are part of the team or you are the leader. In both cases, it is necessary to look for general and individual solutions.
