<![CDATA[This study primarily aims to examine the extent to which organizational culture, working environment conditions, and motivation drive the loyalty commitment of educators at SMA Negeri 1 Samalanga. Employing an empirical quantitative approach, the study analyzes responses from 61 subjects, which were then quantified using multiple linear regression modeling via SPSS. Individual hypothesis testing reveals that organizational culture significantly and positively influences teacher loyalty (t-calculated = 6.345 > t-table = 1.672; p = 0.000 < 0.05). A conducive working environment also demonstrates a substantial positive impact on teacher commitment (t-calculated = 3.093 > t-table = 1.672; p = 0.003 < 0.05), followed by the motivation variable, which is proven to significantly accelerate loyalty (t-calculated = 5.221 > t-table = 1.672; p = 0.000 < 0.05). Comprehensively and simultaneously, the combined effect of these three predictors is verified to significantly determine teacher loyalty, as evidenced by an F-calculated value of 28.841 (exceeding the F-table value of 2.77) at a probability level of 0.000 < 0.05. The strength of the association between these constructs is classified as very high, as reflected by the correlation coefficient (R = 0.776). Furthermore, the calculation of the coefficient of determination (R² = 0.603) confirms that 60.3% of the variation in teacher loyalty is driven by the synergy of organizational culture, the work environment, and motivation, while the remaining 39.7% stems from external variables not included in this analytical framework.]]>
