Sintesi	The Organizational Justice Scale (OJS) measures employees' perceptions of fairness in organizational settings across four dimensions: distributive justice (fairness of outcomes), procedural justice (fairness of decision-making processes), interpersonal justice (respectful and dignified treatment), and informational justice (honest and adequate communication). Developed by Colquitt (2001) and building on earlier work by Moorman (1991), the OJS assesses how fairly employees perceive they and their work are treated, predicting organizational commitment, citizenship behavior, and turnover.	The Psychological Safety Scale (PSS), developed by Amy Edmondson in 1999, measures team members' shared perception that they can take interpersonal risks—speaking up, asking questions, admitting mistakes, proposing new ideas—without fear of embarrassment, punishment, or rejection. The 7-item scale captures a team-level construct fundamental to learning, innovation, and psychological well-being. High psychological safety predicts team performance, learning from errors, information sharing, and adaptive responses to change.
