Abstract
This research paper investigates the implementation of sustainable development practices in Algerian family businesses. Furthermore, it examines whether the application of these practices varies based on factors such as job title, educational attainment, and professional experience. A quantitative research methodology was employed, utilizing a questionnaire survey administered to 100 middle and upper-level management employees in these companies. Data analysis was conducted using SPSS V.25. The findings revealed that Algerian family businesses engage in practices aligned with all three TBL of SD (economic, social, and environmental). Moreover, no statistically significant differences in the application of these practices were observed across job titles, educational levels, or professional experience.
