<![CDATA[This study examines the associations of work motivation, career development, and work environment with employee loyalty among civil servants at the District Education Office of Asahan Regency, North Sumatra. A cross-sectional census obtained questionnaire responses from 64 non-executive civil servants. Ordinary least squares regression indicated that the three predictors were jointly associated with loyalty, F(3, 60) = 7.69, p < .001, R² = .278, adjusted R² = .242. Work environment showed the largest conditional association (B = 0.599, 95% CI [0.292, 0.906], f² = .253), followed by career development (B = 0.421, 95% CI [0.168, 0.674], f² = .185) and work motivation (B = 0.403, 95% CI [0.004, 0.802], f² = .068). Predictor-specific f² values were calculated from each predictor’s incremental R² relative to the full-model residual variance; for a one-degree-of-freedom coefficient test, this is algebraically equivalent to t²/df. The results describe conditional associations rather than causal effects. Moreover, respondent-level data were unavailable for independent reanalysis, and item-total correlations and Cronbach’s alpha do not establish construct or discriminant validity. The unexplained variance cannot be attributed to job embeddedness, pension position, or limited mobility because these factors were not measured. Job embeddedness is therefore retained only as a theoretically plausible explanation for future testing.]]>
