Workplace bullying and turnover intentions of nurses : the multi-theoretic perspective of underlying mechanisms in higher-order moderated-serial-mediation model

Purpose: This study examines the relationship between workplace bullying (WPB) and the turnover intentions (TIs) of nurses, both directly and indirectly, i.e. through serial mediation of psychological contract violation (PCV) and poor employee wellbeing (EWB). And that with the moderating effect of servant leadership (SL) on its final path to TIs of nurses. Design/methodology/approach: A total of 285 nurses voluntarily participated in the survey through convenient sampling from 13 different district hospitals. The authors performed partial least squares structural equation modeling (PLS-SEM) to test the study's measurement and structural models. Findings: Overall, results indicated 62% prevalence rate of WPB and TIs of nurses had 67% variance explained by the exogenous factors. Workplace bullying was found to have direct as well as indirect relationship with TIs of nurses. For the latter, PCV and poor EWB were found to have partially mediated, both singly and serially. The moderating effect of SL on the serial mediation pathway was negative and significant. Originality/value: Drawing on a tripartite theoretical perspective, this study illuminates the mechanism underlying WPB-TIs relationship with an advanced multivariate statistical technique in the nursing work setting in a developing country.
