Abstract
Job satisfaction is a key component of organizational well-being and performance. This study explores the relationship between job characteristics (demands and resources), organizational and group identification, and affective job satisfaction, drawing on the Job Demands-Resources model and social identity theory. METHODS: A cross-sectional design was used with a sample of 420 employed individuals (49% men and 51% women), with a mean age of 41.58 years (SD = 9.95). Participants completed an online questionnaire assessing job demands (quantity and complexity), job resources (competency development, use of competencies, and decision latitude), and identification (organizational and group). Most participants held a university degree (48.1%) and had a permanent contract (79.8%). A MIMIC model was applied to test the hypothesized relationships. RESULTS: Job demands defined by quantity were inversely associated with job satisfaction, while competency development and use were positively associated. Organizational and group identification also showed significant positive relationships with job satisfaction. However, task complexity and decision latitude were not significant predictors. DISCUSSION: These findings underscore the importance of integrating both job design and social identity factors to enhance job satisfaction and inform organizational strategies aimed at promoting employee well-being.
