This study explored differences in RNs' perceptions of their work environment by both years in the profession and current position. A statistically significant difference was found for RNs' perceptions of Supervisor Support based on number of years in current position. Those RNs with less than 2 years in their current position perceived the greatest Supervisor Support (X = 6.96; P = .03).
