This paper examines and analyses the differences in job satisfaction among the conventionally employed and teleworkers. Differences were examined for three control variables: gender, age and education of the respondents. The research was conducted in West Balkan countries (Bosnia and Herzegovina, Croatia, Montenegro, North Macedonia and Serbia), and included 313 respondents (conventionally employed and teleworkers). Teleworkers are more satisfied than conventionally employed. This is most evident through satisfaction with all forms of compensation, procedures and associates. Job satisfaction is higher in men, both those who work conventionally and who telework. Men are significantly more appreciative of opportunities for advancement, as well as achieving additional benefits and rewards. Younger respondents have greater job satisfaction than older respondents, but this only applies to the conventionally employed. There are no differences in job satisfaction among teleworkers in terms of dependence on age. Job satisfaction does not depend on the respondents' level of education of, and this applies to both conventionally employed and teleworkers. Companies that apply telework evaluate the results of their employees' work and the contribution they provide to the company more objectively, and accordingly, they reward and promote employees adequately. Thus, all age groups and educational categories of employees see their chance in teleworking conditions.
