April 14 2026
When a new team member joins, leaders often focus on getting the individual up to speed while overlooking the broader impact on the rest of the team. Over time, this can create misalignment and friction within team dynamics, even when performance might appear strong on the surface.
In this episode, TMG’s Robert Williams is joined by Courtney Hamilton and John Nasr to look at what happens to the team as a whole in these moments. They explore the idea of “new member, new team,” challenging the assumption that teams change only when leadership does. They also discuss how leaders can use these moments to reset norms and clarify expectations.
