This study aims to examine the effect of organisational commitment and employee’s pro-environmental behaviour at home on their intention to adopt green practices at the workplace in the context of hotel industry, by taking the theory of planned behaviour as a conceptual framework. Hotel employees play a critical role that affects customers' experiences, which then affects the overall hotel performance. However, the mechanism that affects their behavioural intention has yet to be investigated properly. Thus, a survey was conducted to collect the data from employees working in green and non-green hotels in Malaysia. Overall, there were 407 responses received, which represented a response rate of 55.75 percent. Then, a set of hypotheses was tested using the structural equation modelling. The empirical results indicate that organisational commitments have a positive effect on the attitude for engaging in a green behaviour and subjective norm, which in turn influenced employees’ intention to adopt green practices at work. Meanwhile, employees’ pro environmental behaviour at home has an indirect impact on employee’s intention to adopt green practices in the workplace through their attitude for engaging in a green behaviour, subjective norms, and perceived behavioural control. The findings lead to a theoretical contribution by incorporating another theory into the theory of planned behaviour, which is the social bond theory through organisational commitment and spill-over effect through pro environmental behaviour at home. Subsequently, a practical recommendation from this research is attainable to policy makers and hotel providers in order for them to understand and increase employees’ willingness to adopt green practices at the workplace. / The full text will be available at the end of the embargo: 15th Dec 2026
