Hybrid working arrangement received significant popularity during the post COVID -19 era as travel restrictions and social distancing moved remote working from an option to a necessity. Employees generally resist accepting changes as they are willing to stick with the status quo which is more comfortable. Thus, stimulating employees for adopting a hybrid working model becomes a challenging task and scholars' and practitioners' attention is received on the phenomenon of hybrid working model adoption behaviors of the organization and employees. However, the phenomenon is underexplored in the context of an emerging economy. This study aims at identifying the determinants of intention to adopt hybrid working model by the executive and above-level employees of the Sri Lankan apparel industry. The model was developed using the UTAUT model. Data was collected using a self-administered questionnaire from the sample of 101 executives and above-level employees from the three leading apparel companies in Sri Lanka. A stratified sampling technique was used while the list of employee details provided by the administrative officers of the three apparel firms was taken as the sample frame of the study. Multiple regression analysis was used to test the hypothesis and the findings revealed that performance expectancy; effort expectancy, and social influence explained the intention to adopt the hybrid working model. This study contributes to the theory by enhancing the understanding of HWM adoption behavior of employees in developing economies as the study identifies drivers of HWM adoption behavior of the executives and above-level employees in the apparel sector specifically in Sri Lanka. The study found that the UTAUT model explains only 38 percent of the variance of the intention to adopt HWM. This indicates that some variables which have not been specified in the model have an impact on determining the HWM adoption behavior of the employees. Thus, future studies are opened up for further development of the research model.
