PurposeThe purpose of this study intends to examine the influence of green human resource management (GHRM) on green service behaviors through the mediating effect of green knowledge sharing based on bank employees' perceptions.Design/methodology/approachThe study analyzes 365 frontline employees' perceptions from the banking industry in Bangladesh using partial least square.FindingsThe findings show a significant positive direct influence of GHRM on green in-role, extra-role service behavior and green knowledge sharing. Green knowledge sharing is also found to have a significant mediating effect between GHRM and green service behaviors.Research limitations/implicationsThis study considers perceptions of employees of the private commercial banking organizations, and thereby, its findings cannot be generalized for all other service organizations in the context of Bangladesh.Practical implicationsThe study demonstrates that GHRM can influence employees' green service behaviors via green knowledge sharing.Originality/valueGreen banking is an emerging trend that deserves more attention. There is growing recognition that green banking is not an “automatic” process but requires that banking management promote green service behavior among their employees. This study extends the research on GHRM by focusing on how it impacts green service behavior through the mediating role of green knowledge sharing. The paper provides practical insights for organizations looking to improve green service behaviors among employees.

PurposeIn this research, we investigate the effect of high-performance work practices (HPWPs) on medical professionals' work outcomes through the mediating effect of perceived organizational support (POS).Design/methodology/approachThe study analyzes the opinions of 218 medical doctors from private hospitals in Bangladesh, employing Partial Least Square-Structural Equation Modeling (PLS-SEM).FindingsWe find that HPWPs enhance employee performance and POS and minimize turnover intention. POS also has a substantial influence on both employee performance and turnover intention. Moreover, POS finds a significant mediating effect on HPWPs and performance as well as HPWPs and turnover intention relations.Research limitations/implicationsThe current research focuses on medical doctors who are presently working in private hospitals in Bangladesh.Practical implicationsFirst, the hospital would recognize the role of employee perceived HPWPs. Second, they might understand how HPWPs would utilize and maintain employees effectively via POS that might further improve the healthcare industry. Suggestions for future research indicate the models potential to provide optimal workplace environments that can benefit organizations as well as improve employee performance.Originality/valueThe study would provide a unique insight into the higher-order HPWPs system and its effects on the health care organizations in developing country contexts like Bangladesh. This study also extends the research on POS as a mediator between higher-order HPWPs and employee outcomes in the organization.
