This study offers insights into the underlying mechanism behind the relationship of role clarity and organizational commitment in an integrated model of multiple serial mediation effects of job involvement and job satisfaction. In a developing country context, a total of 330 social workers working in four different human service organizations completed the survey. The PLS-SEM indicated a good fit between the data for both of the study measurement and hypothetical structural models. We ascertain partial mediation effects of job involvement and job satisfaction in simple and jointly as serial mediation models between the direct relationship of role clarity and organizational commitment.

Purpose: This study examines the relationship between employees' perceptions of informational fairness and project performance. Furthermore, it examines if this relationship is sequentially mediated by (1) knowledge sharing and role clarity and (2) communication openness and role clarity. Design/methodology/approach: Data are collected from 302 full-time employees of seven project-based construction organizations in Pakistan. Data are analyzed through variance-based structural equation modeling technique and the Preacher and Hayes' bootstrapping procedure. Findings: Results indicate that project employees' perceptions of informational fairness positively predict project performance. Moreover, this relationship is sequentially mediated by (1) communication openness and role clarity and (2) knowledge sharing and role clarity. Originality/value: This study provides further insights on the informational fairness and project performance relationship by examining their underlying mechanisms. It draws on the much ignored context of Pakistan, and offers some implications for managers and researchers with regard to how behavioral factors may further enhance project performance.
