Kumar, P.K.Saha, S.Anand, A.2026-02-042022International Journal of Public Sector Management, 2022, 35, 5, pp. 549-5679513558https://doi.org/10.1108/IJPSM-09-2021-0218https://idr.nitk.ac.in/handle/123456789/22529Purpose: The purpose of this study is to determine whether participation in decision-making (PDM) and organizational learning (OL) act as mediating factors in the relationship between supportive culture and job involvement. Design/methodology/approach: Data were collected from 712 employees working in different public sector undertakings (PSUs) across India. Necessary condition analysis (NCA) analysis and partial least square (PLS) analysis were used to test the proposed hypotheses. Findings: The findings of the present study indicated that PDM and OL act as a full mediator respectively in the relationship between supportive culture (SC) and job involvement (JI). The SC was positively and significantly related to PDM and OL. However, SL did not have a significant impact on JI. In addition, higher PDM and OL were found to be significantly impacting JI. Practical implications: The results suggest that PDM and OL facilitate the impact of SC on JI and may help organizations to retain their employees. The implications of these findings for all hierarchical levels in PSUs are discussed. Originality/value: OL and PDM as mediators between SC and JI have received very little attention from the context of India. The results add to the growing literature of culture from a non-western context as this study is based on Indian samples. This study has taken care to provide unbiased responses by utilizing data from employees working in various functional units of the organizations. © 2022, Emerald Publishing Limited.EmployeesJob involvementOrganizational learningParticipation in decision makingPublic sector undertakingsSupportive culture
