The quality of the relationship between nurses and their supervisor may contribute to
eliminate intention to leave workplace by nurses. The study aimed to identify perceived nursing
supervisor support and its relation to turnover intention among staff nurses. Research design: A
comparative correlational design was utilized to meet the aim of this study. The study setting:
this study was conducted at critical and non-critical care units at Benha University Hospital. The
study sample: composed of all staff nurses (293) who are working in the above mentioned
setting; 149 of staff nurses working at non-critical care units and 144 staff nurses working at
critical care units. Tools: two tools were used for data collection; Perceived Nursing Supervisor
Support Questionnaire and Turnover Intention Questionnaire. Results: more than two fifth of
staff nurses had moderate perception level regarding nursing supervisor support at critical and
non-critical care units. Staff nurses working at critical care units had higher turnover intention
level than staff nurses working at non-critical care units. Conclusion: there was highly
statistically significant negative correlation between perceived nursing supervisor support and
staff nurses' turnover intention at critical and non-critical care departments. The study
recommended: that nursing supervisors should be trained to provide constructive feedback and
support to their staff nurses which may help to decrease turnover intention.
