Suppressing the benevolent interpersonal emotions of employees for customers has a negative impact on customer satisfaction, as indicated for the first time in a new study conducted by Prof. Dana Yagil of the Department of Human Services at the University of Haifa. The study was published in the journal Motivation and Emotion. “Suppression of positive interpersonal emotions is contrary to natural behavior in social interactions,” said the researcher.
