Abstract:
This study examined the relationship between perceived organizational justice and the frequency of
interpersonal conflict in group-based workplace settings, with group size explored as a potential
moderating factor. Using a descriptive-correlational design, survey data were collected from 196 full-time
employees across the education, healthcare, banking, and business process outsourcing (BPO) sectors in
the Philippines. Respondents completed the Organizational Justice Scale (Colquitt, 2001) and the
Interpersonal Conflict at Work Scale (Spector & Jex, 1998). Results revealed a significant negative
correlation between perceived justice and conflict frequency, with interpersonal and procedural justice
showing the strongest associations. Group size, when analyzed as a continuous variable, significantly
moderated the justice–conflict relationship, though threshold-based comparisons (small vs. large groups)
did not yield significant results. These findings highlight the role of justice perceptions in preventing
workplace conflict and underscore the importance of tailoring communication and fairness strategies to
team size and sector-specific contexts. The study contributes to local literature by integrating justice and
conflict dynamics within the framework of Philippine organizational settings.
