Today, it is possible to assert that there is also a collective Emotional intelligence which affects the productivity of teams. Based on Druskat and Wolf, «we define group emotional intelligence as the ability of a group to generate a shared set of norms that manage the emotional process in a way that builds trust, group identity, and group efficacy» \cite{JJ1}. In \cite{EE1}, Elfenbein affirms that “teams with a greater average emotional intelligence achieve a better team functioning than groups with a lower emotional intelligence [do].” Moreover, in a team, “the ability to understand one another’s emotional expressions explained 40% of the variance in team performance.” Elfenbein describes Team EI as the emotional savvy exhibited when team members interact with each other.
