This study investigates the relationship between green transformational leadership (GTL), job satisfaction (JS), and the mediating role of 'intention' in Pakistan's pharmaceutical industry within the framework of the resource-based view (RBV) theory. The research uncovers that GTL, encompassing environmental consciousness, ethical conduct, and innovation, is a unique organizational resource that shapes employees' intentions toward embracing sustainable practices. A quantitative methodology was adopted to achieve the aims of the study. Data were collected through an online survey to manage the data (418 valid responses), and Smart-PLS structural equation modeling (PLS-SEM) was employed to hypothesize a model. The results demonstrate that GTL had little significant direct effect on JS. This study also found that intention has a full mediation effect between GTL and JS. Additionally, the study found that the correlation among GTL is affected by JS and intention. This study contributes to the literature and body of knowledge on green human resource management and organizational behavior through the lens of RBV theory.
