The Vertical Dyad Linkage Theory is a theory that deals with individual dyadic relationships between leaders and their subordinates.  It is also widely known as the Leadership Member Exchange (LMX) Theory.  The theory was originally developed in 1975 by Fred Dansereau, George Graen and William J. Haga.  Graen, G.B. and Uhl-Bien, M. (1995) `Relationship-based approach to leadership: Development of Leader-member exchange (LMX) theory of leadership over 25 years: Applying a multi-level multi-level multi-level multi-domain perspective, The Leadership Quarterly, Volume 6, Issue 2, Summer 1995, S 219-247.

To continue to be seen by the leader as an excellent member of the team, the people in the group show admiration, confidence and perseverance. In addition, “high-level scholarships and mutual and quality leadership” (Ngo, D. 2012. Introducing LMX [online]. LinkedIn Corporation. Available at: www.slideshare.net/gutierrezdaisy/lmx-presentation?related=1. [Access November 2, 2015])  the development of relationships within the team takes place. The organizational environment can be improved by the exchanges that take place at this stage, as they lead to modernization and, in general, more positive employment.  In a study by Erdogan, Bauer and Walter (2015) on people in the workplace, the debate is about the fact that the group members, who are experiencing quality exchanges with the Leader, will most likely be recruited by the other members of the Out group. The reason is that group members are closely related to the manager. As a result, the Out group develops other relationships with the group to facilitate the leader`s access and ultimately communicate more effectively with the leader.
Since The members of the Out group establish positive relationships with the manager, this can be a method of leaving their subgroup and being part of the group. (Erdogan B, Bauer T., Walter J. 2015. Actions that help and words that hurt: Help and gossip as moderators of the relationship between Leader members exchange and network consultation centrality. The psychology of the staff. 68. 185-214).  Ultimately, group members can understand how the leader prefers team members and is dissatisfied with his or her leadership style. As a result, they may have the desire to leave the current team or workplace.  In a test of hypotheses drawn from the literature around the Vertical Dyad Linkage (VDL) Model of Leadership, 45 Dyads supervisors-subordinate were studied in a different environment from much of the previous VDL research.
