In this study, the researcher examined the sociability of the organization using 4 factors including "receiving training, understanding, employees’ support, and future vision of the organization". Rough set theory was used to analyze the data. Accordingly, after the formation of the standardized tables, incompatible and compatible cases were determined and reduction tables were formed. Finally, the overall results showed that when the level of training in the organization is high, sociability would be also at higher level. Additionally, the results showed that when the factors of understanding and employees’ support are at the moderate level, sociability of employees increases. In addition, based on the results achieved, organization vision greatly increases the sociability of employees
