The study investigated the impact of high‐involvement work systems (HIWS) on knowledge‐sharing intention (KSI) through the mediation of organizational commitment (OC) and the moderation of workplace allocentrism, particularly in the manufacturing units of small and medium enterprises operating in Pakistan. Data collection involved 328 workers, utilizing self‐administered structured questionnaires translated into Urdu to ensure understanding and inclusivity. SmartPLS software was used to analyze data using the structural equation modeling technique for the examination of complex relationships between multiple variables simultaneously. The findings suggest that the association between HIWS and KSI strengthens among the individuals high in workplace allocentrism and that cultural factors play a significant role in shaping how employees respond to HIWS and engage in knowledge‐sharing behaviors. The study highlights the importance of considering cultural factors in organizational practices and strategies, thus providing novel insights for entrepreneurs to enhance the performance, innovation, and competitiveness of their enterprises through a knowledge‐sharing culture. Overall, study offers valuable contributions to both academia and practice by shedding light on the intricate relationships between HIWS, KSI, OC, and workplace allocentrism.
