This study investigates the impact of personal variables on job satisfaction among employees of the Civil Protection Directorate in Djelfa Province. Using a descriptive analytical approach, the research surveyed a stratified random sample of 261 employees, with 248 valid responses analyzed. The study examined the influence of several personal variables—age, experience, educational level, obtained qualification, marital status, number of dependent children, military rank, workplace location, job role, and work schedule—on job satisfaction. Statistical analyses, including one-way ANOVA and independent samples t-tests, revealed that educational level, marital status, and workplace location significantly affect job satisfaction, while other variables showed no statistically significant impact. Notably, employees with lower educational levels and those who are single reported higher satisfaction levels. The findings underscore the importance of aligning job roles and organizational environments with employees’ personal characteristics to enhance satisfaction and performance within semi-military institutions
