Recent literature in environmental management suggests that fostering employees’ innovative behaviour in green service is vital for enhancing the environmental sustainability of hospitality organizations. Despite this, few efforts have been made to understand how green entrepreneurial leadership (GEL) relates to green service innovative behaviour (GSIB). This study aims to examine whether GEL can promote GSIB among hospitality employees through the serial mediation of green learning orientation (GLO) and green knowledge acquisition (GKA) using the conservation of resources theory. The authors expect environmental dynamism to strengthen the relationship between GEL and employees’ GSIB, leveraging the resource-based view theory.

This study collected data through a multi-wave survey (four waves, two weeks apart) from 341 employees working in three-to-five-star hotels in Pakistan’s major cities. The authors used partial least squares structural equation modelling to evaluate the hypotheses proposed in the theoretical model.

The study revealed a significant relationship between GEL and employee GSIB, mediated by GLO and GKA. In addition, environmental dynamism strengthened the relationship of GEL with employee GSIB.

The research advances the literature on GEL in the hospitality sector by providing insights into the mediating and moderating processes that translate GEL into GSIB among hospitality employees. Moreover, the research provides important implications for hotels investing in green initiatives and looking for ways to foster employees’ GSIB.

Employee green behavior contributes to the achievement of hospitality organizations’ sustainability goals. However, there is a need to examine how green human resource management (GHRM) fosters employees’ green behavior. Anchored on the conservation of resources (COR) theory, we anticipate that GHRM may have double-edged effects on employees’ organizational citizenship behavior for the environment (OCBE) via two opposing mechanisms (e.g. environmental passion and emotional exhaustion). Moreover, we expect that the relationship of GHRM on environmental passion and emotional exhaustion depends on environmentally specific empowering leadership (ESEL).

The data were garnered from 356 hospitality employees in Pakistan and analyzed using partial least squares structural equation modeling (PLS-SEM).

The findings revealed a significant and positive link between GHRM and employee OCBE and environmental passion and a significant and negative relationship between GHRM and emotional exhaustion. Similarly, the link between environmental passion and employee OCBE was significant and positive and between emotional exhaustion and employee OCBE was significant and negative. Our results indicate that the impact of GHRM on OCBE among hospitality employees was mediated by environmental passion and emotional exhaustion. Further, ESEL strengthened the association of GHRM with environmental passion while mitigating the effect of GHRM on emotional exhaustion.

Anchored on the COR theory, our study provides novel empirical evidence by investigating the mechanisms and boundary conditions between GHRM and employee OCBE nexus in the hospitality realm.

In this paper, the implementation of lean manufacturing and six sigma practices among Malaysian manufacturing SMEs toward achieving sustainable performance was investigated. Furthermore, intention to implement IR 4.0 technologies among manufacturing SMEs was also examined.

The primary data were collected from 120 manufacturing SMEs across Malaysia using organization as the unit of analysis. The data were collected using the six-point Likert scale questionnaire.

Based on research findings, about 86% Malaysian manufacturing SMEs implement 6s. Nevertheless, lean and 6s has an influence on sustainable performance among Malaysian manufacturing SMEs. Only about 32.5% Malaysian manufacturing SMEs have the intention to implement IR 4.0 technologies. This study results imply that IR 4.0 technologies implementation among Malaysian manufacturing SMEs are still at infant stage though lean and 6s concept is known by the manufacturing SMEs.

This study has implications for future researchers to explore application of IR 4.0 technologies among manufacturing SMEs. Therefore, there is need to create awareness about the application of IR 4.0 technologies suitable for manufacturing SMEs in order to remain sustainable for local and foreign competitors. From the perspective of system theory, there is an interconnection network across each department in a whole system. More so, sustainable performance can continuously change and improve the system in any organization.

From the view of SMEs policy makers, this study should be use to encourage SMEs to adopt technologically inclined practices. Accordingly, this research recommends government bodies to help support the implementation of sustainable practices due to their sizes and inadequate resources involved. Therefore, the role of government in providing suitable policies that could be beneficial to manufacturing SMEs toward achieving sustainable practices cannot be overlooked. Through proper government support, Malaysian manufacturing SMEs will be able to survive both locally and internationally and also gain competitive advantage.

The main contribution of this paper includes integrated effect of lean manufacturing practices and six sigma implementation among manufacturing SMEs and prioritizing implementation of IR 4.0 technologies to be executed by manufacturing SMEs.
