The aim of this research was to investigate the relationship among intrinsic motivation, authentic leadership and high-performance work system (HPWS) on university faculty members with the mediating role of knowledge sharing. A total of 286 full-time faculty members of public universities from 30 universities of Punjab, Pakistan were interviewed using a five-point Likert-scale question-naire, adapted from the literature. The results of PLS-SEM indicate that authentic leadership and HPWS had a significant effect on faculty member’s creativity whereas intrinsic motivation showed an insignificant relationship with creativity. Results further highlight that knowledge sharing mediated the relationship between HPWS and employee’s creativity, however, no mediation effect was found for intrinsic motivation and authentic leadership with employee creativity.
