This research aims to examine the influence of promotion and organizational culture on employee work motivation at the Bureau of Organization and Human Resources (OSDM) of the Ministry of Industry of the Republic of Indonesia. A quantitative approach was employed using multiple linear regression analysis. The study involved 40 employee respondents. The regression results indicated that promotion had a significant partial effect on work motivation, with a regression coefficient of 0.626 and a significance level of 0.003 (t-value = 3.160 > t-table = 2.026). Similarly, organizational culture also had a significant partial effect, with a regression coefficient of 0.400 and a significance level of 0.040 (t-value = 2.129 > t-table = 2.026). Simultaneously, both independent variables exerted a significant influence on work motivation, as shown by an F-value of 11.656 and a significance level of 0.000. The coefficient of determination (R Square) of 0.387 indicates that 38.7% of the variance in work motivation is explained by promotion and organizational culture, while the remaining 61.3% is attributed to other factors outside the model.
