This study explores the relationships between positive and negative Organizational Behaviors and Workaholism; and the relationship of these OBs with productivity and gender of engineering students in Pakistan. Most of the researchers have studied OBs among faculty or administrative staff in universities. The study of these behaviors among students is a new area. An eight-stage innovative qualitative codebook thematic analysis was used to analyze semi-structured interviews from 22 faculty members to explore the relationships of OBs with productivity and gender of engineering students. A comprehensive model of relationships between OCB, DB, WA, and the productivity of engineering students has been built which was previously missing from contemporary literature. Gender has also been found to have a relationship with various behaviors. The findings here are important for practitioners and scholars for a better understanding of the relationship of OBs with the productivity of engineering students, to enhance their productivity through the promotion of desired behaviors.
