Being a much more recent topic, there is not much literature on the assessment of Team Emotional Intelligence. The election of the TEI Test over WEI-S was more closely related to the nature of the team under study. Existing literature clarify differences between in-source and outsourced employees. The different conditions contribute to a negative organizational climate which drives to a lower (or null) identification and sense of belonging of subcontracted professionals and, consequently impacts the efficiency of the team \cite{brooks2006understanding,zalewski2018working}.
