This study aims to assess the relationship between workplace ostracism and the procrastination behavior of nurses, as well as examine the effect of organizational silence on this relationship. Controlling workplace ostracism and eradicating time wasters, especially procrastination behavior among nurses, are key strategies that add value to organizational effectiveness. In addition, remaining silent about significant issues facing nurses is a devastating approach to the success of both healthcare organizations and the nursing profession. A cross-sectional descriptive correlational exploratory research design was used to conduct the study. Data were collected from 352 nurses recruited from three large university hospitals in Alexandria, Egypt. Four instruments, namely, the Workplace Ostracism Questionnaire, the Organizational Silence Scale, the Active Procrastination Scale, and the Unintentional Procrastination Scale, were used. Structural equation modeling was used to test the hypothesized relationships among the variables. The findings demonstrated a significant positive and moderate association between workplace ostracism and both active and passive procrastination behaviors among nurses. Moreover, there was a strong positive and significant correlation between organizational silence and workplace ostracism. The results of mediation revealed that the indirect effect of workplace ostracism on both active and passive procrastination behavior through organizational silence was statistically significant, suggesting that organizational silence partially mediated this relationship. The study highlighted the ongoing challenges posed by toxic workplace issues, such as organizational ostracism and silence, as significant factors contributing to nurses' procrastination behaviors. Not only do these factors directly impact nurses' productivity, but they also interact to exacerbate negative outcomes in nursing care. Addressing these toxic dynamics is critical to improving nurse performance and ensuring quality care in healthcare settings. This study offers new insights for navigating toxicity and upgrading nursing productivity in healthcare organizations through fostering a more inclusive and communicative work environment. Promoting team cohesion and ensuring that all staff members feel valued and included can reduce feelings of isolation that may lead to procrastination. Also, creating safe spaces for nurses to voice concerns without fear of reprisal could significantly diminish passive procrastination, which ultimately enhances overall patient care quality and organizational efficiency.
