Purpose: The authors' study aims to examine to what extent managerial religiosity does influence human resource (HR) managers' attitudes towards women as managers (ATWM), and whether such posi(nega)tive attitudes can facilitate or impede the adoption of supportive HR practices (SHRP). Design/methodology/approach: This study empirically examines a theoretical model by employing partial least squares-based structural equation modelling (PLS-SEM) using quantitative survey data from 182 HR managers in Bangladesh. Findings: The authors' findings reveal that individual religiosity may adversely affect HR managers' attitudes towards recognising women as managers, and such stereotyped attitudes, in turn, may attenuate the adoption of supportive HR practices in organisations operating particularly in highly religious socio-culture environments. Research limitations/implications: The findings of the authors based on self-report, cross-sectional survey data collected from HR managers/equivalent working in the Bangladeshi organisations may unlikely to predict the ATWM held by the top leaders in organisations and other employees in similar socio-cultural settings. Practical implications: The authors' findings suggest that religiosity cannot be ignored in management development and recruitment processes for HR managers, particularly in a society characterised by relatively weaker formal institutions and people with a higher degree of religiosity. Originality/value: To the best of the authors' knowledge, this study is the first attempt explicating how top management's religiosity interacts with the attitudes towards the acceptance of women as managers and how such attitudes can influence the adoption of supportive HR practices.
