It has been my experience that few people understand what it means to be a team. Team members may not only share successes and failures but also responsibilities, duties and rights.
Especially when external influences affect the team, e.g. because in hierarchical environments the communication with a team usually happens through a dedicated person or because within the team specialists represent their own areas, it happens that a team is not seen as a unit which then negatively affects the communication with and within the team.
Team Topologies deals with this in the chapter "Team-First Thinking" and provides some answers under the heading "Team Members Need a Team-First Mindset". But what if the disruptive factors lie outside the team or are even to be found in the organization's culture?
My, admittedly somewhat dystopian question, aims more in the direction of how this change in thinking can be achieved without immediately removing all "team toxic" people, because this is simply not always possible, especially if these people are not team members.
