This study draws on psychological contract theory, according to which organizational members reciprocate detrimental treatment they perceive with negative work-related attitudes and behaviors. Organizational attitudes were predicted by both breach and violation. This study demonstrates the importance of psychological contract breach and violation to nurses. Nursing administrators and leaders are advised to monitor and balance the expectations of nurses. They should recognize the importance of the interpretive process leading to feelings of betrayal and anger, thus providing the opportunity to manage perceptions of breach.
