Investigating the impact of temporary nurses on permanent nurses' commitment via perceptions of illegitimate tasks:...

To explore illegitimate tasks as a potential mechanism that links permanent nurses' perceived exposure to temporary nurses to lower levels of affective organizational commitment.

A time-lagged cross-sectional survey study.

Survey data from N = 239 permanent nurses in the German-speaking part of Switzerland were analysed via Structural Equation Models.

The study revealed a negative relationship between permanent nurses' perceived exposure to temporary nurses and their level of organizational commitment that was mediated by perceptions of unreasonable and unnecessary tasks.

Healthcare institutions increasingly depend on temporary nurses to fill staffing vacancies. Our data suggest that the deployment of temporary nurses may have adverse effects on permanent nurses' affective organizational commitment via perceptions of illegitimate tasks.

Our quantitative survey study provides a novel, theory-driven understanding of how perceived exposure to temporary nurses may impact work-related attitudes of permanent nurses.

Our findings suggest that the clinical community should limit permanent nurses' exposure to temporary nursing staff to protect their commitment. If this is not possible, we encourage strategies to counteract associated feelings of illegitimacy, for example, by showing appreciation for permanent nurses' willingness to take over responsibility for temporary nurses.

The study adheres to the STROBE reporting guidelines for cross-sectional studies.
