Abstract: In the dynamic landscape of contemporary organizations, the phenomenon of silo mentality casts a ripple effect on vital facets of communication and collaboration. This article explores the intricate relationship between silo mentality and the communication-collaboration dynamics within organizations. Employing a quantitative approach with a sample size of 382 millennials employed in the IT industry of Sri Lanka, this research sheds light on how silo mentality among millennials has lasting consequences. Findings show that the silo mentality not only creates barriers that hinder cross-functional information exchange but also compromises the spirit of collaboration intrinsic to millennial work culture. This article illustrates how silo mentality disrupts the flow of ideas, curtails knowledge dissemination, and hinders project synergy. These effects cascade throughout the organization, leading to under optimized team performance. The findings of this study prove implications for organizational leadership, suggesting the need for proactive interventions to dismantle silo-driven barriers.
