Also, employees are always faced with the problem of meeting up with their targets of account opening, deposit mobilizations and investment. These ultimately make employees to depend on one another to collectively achieve the goals of the organization. It is as a result of this problem the study seeks to examine the mediating effect of task interdependence on the relationship between Organizational Citizenship Behaviour and the Performance of DMBs.

The result found as a result of introduction of mediation variable revealed that helping behaviour and civic virtue has positive relationship and significant effect on the performance of DMBs in Kaduna metropolis. Sportsmanship has significant effect but negative relationship with performance of DMBs in Kaduna metropolis. It is also discovered that task interdependence mediates OCB-performance relationship.
