AbstractThis study examines the effects of transformational leadership (TL) and job complexity (JC) on organizational innovation (OI), with a focus on the moderating role of job autonomy (JA). The study implemented a quantitative, cross-sectional method with valid and reliable instruments to collect data from 368 staff members of the Sharjah Roads and Transport Authority (SRTA) in the UAE using a systematic probability sampling method. The researcher used descriptive data, factor analysis, and covariance-based Structural Equation Modelling (CB-SEM) to analyse the data. The findings reveal a significant positive effect of TL on OI (_=0.511, t = 8.241, p < 0.001), and a positive impact of JA on OI (_ = 0.156, t = 3.346, p < 0.001). However, the study also found that JA moderates the relationship between TL and OI (_ =- 0.178, t = -4.567, p < 0.001). Conversely, JC negatively affects OI (_ = -0.34, t = - 6.744, p < 0.001), even as JA moderates the JC-OI relationship (_ = 0.039, t= 2.193, p < 0.05.....
