Based on social learning theory, expectancy violation theory and resource conservation theory, this study explores how the boss phubbing (Bphubbing) affects employees' performance. Through the survey and data analysis of 215 employees, the results show that: (1) There is a negative correlation between Bphubbing and employee job performance. (2) Employees ‘ psychological capital plays a full mediation role in the relationship between Bphubbing and employee job performance.

This study expands the research on the mechanism of the negative impact of improper use of smart phones on the organization, which is conducive to the organization and managers to scientifically view the positive and negative sides of the use of smart phones for information management in the workplace, so as to put forward scientific suggestions for the correct use of smart phones.
