Artificial Intelligence (AI) is increasingly embedded in organizational processes, reshaping how employees perform tasks, make decisions, and relate to their organizations. Despite growing interest in AI-driven transformation, empirical evidence explaining its behavioural implications remains limited, particularly from an organizational behavior perspective. This study examines the impact of AI adoption on key organizational behavior outcomes employee performance, job satisfaction, decision-making effectiveness, and organizational commitment while investigating the mediating role of trust in AI as a psychological mechanism. Using a quantitative, cross-sectional survey design, data were collected from 250 employees and managers across IT, manufacturing, healthcare, and service sectors (banking, education, and hospitality). Descriptive statistics, reliability analysis, correlation analysis, and multiple regression analysis were conducted using SPSS. The findings indicate that AI adoption significantly enhances employee performance, decision-making effectiveness, and organizational commitment, while job satisfaction shows a moderate but significant relationship. Trust in AI partially mediates the relationship between AI adoption and organizational behavior outcomes. The study contributes to organizational behavior and information systems literature by empirically positioning AI as a socio-technical resource and highlighting trust as a critical psychological mechanism for effective AI integration.
