Abstract: This study investigates the effectiveness and productivity of working from home during the COVID-19 pandemic based on seven characteristics from the telecommunications sector in Bahrain, including social, job, teleworker, management, teleworking, crisis and demographic variables. Data from a sample of 104 employers working from home are collected using a questionnaire. A partial least squares regression that ensures the absence of multicollinearity and nonnormality is used as a unique technique to develop two models. The results of these models suggest that the telework effectiveness, teleworker, teleworking and crisis characteristics are statistically significant, whereas the social, job and management characteristics as well as the demographic variables are not statistically significant. These results support the importance of teleworker skills and professional quality variations, such as autonomy, self- discipline, self-motivation, management skills, likely to work during the most prolific period and facilitate working in case of sickness and crisis. Decision makers and managers benefit the most from this study and its results.
