Ten hypotheses are tested in this piece of research. They include the idea that there is a significant relation between job satisfaction in the organization, management style, motivation for achieving success, welfare services, environmental sanitation and work safety, political and religious attitudes of people, reward, career progress path, practice evaluation, and employees' discipline.  Our sample included 336 subjects from 5 provinces.
