Describing a structural model of the predictors of employees' expediency

The purpose of this research is to analyze the effect of SE on EE with emphasis on the moderating role of LMX and the mediating role of employees' unethical tolerance. The current research is applied in terms of purpose and in terms of nature and method, it is descriptive-survey of correlational type. The statistical population of this research (850 people) is the employees of Shohada Kargar Hospital in Yazd city, who were selected randomly through the Cochran 265 formula. Data collection tools were questionnaires: Supervisor Expediency of Greenbaum et al (2018), Employee Expediency of Greenbaum et al (2018), Employee Unethical Tolerance of Froelich & Kottke (1991) and finally LMX of Graen & Uhl-Bien (1995). Validity and reliability The questionnaires indicate that the measuring instruments have good validity and reliability. The results of hypothesis testing by SMART-PLS software and using t-test statistics and path coefficients (β) showed that LMX and employees' unethical tolerance can play a moderating and mediating role, respectively. to have Despite the designed model, it can be expected that the hospital managers can reduce the level of expediency of the supervisor over the expediency of the employees by reducing the leader-member exchange, but by increasing the unethical tolerance of the employees, the level of the supervisor's expediency and the LMX They increase the EE, and this may work in the short term, but in the long term, they will never be able to continue managing the hospital and will deal a fatal blow to its structure.
