The relationships are theoretically grounded in the conservation of resources (COR) theory, which provides a framework for understanding how resources are allocated and depleted in organisational settings. SPSS was used for descriptive statistics and correlation analysis, and partial least squares structural equation modelling (PLS-SEM) was used for measurement and structural model testing. In the study, LN was found to be the antecedent of CS and ITA. In addition, CS was also found to be the antecedent of ITA. Furthermore, it was determined that CS mediates the relationship between LN and ITA. The research extends the literature on LN and CS. The theoretical, managerial, and practical contributions and limitations of the research are presented, along with recommendations for future research.
