When does exposure to daily negative acts frustrate employees' psychological needs? A within-person approach.

Based on self-determination theory, this two-sample study investigates the effects of negative acts on psychological need frustration in greater depth using a within-person perspective. More specifically, through two distinct diary studies, we aim to contribute to the dearth of research on the daily effects of bullying by investigating the daily relationship between exposure to negative acts and need frustration as well as the moderating role of perceived emotional support at work in this relationship. Overall, results from both studies show that employees experience greater need frustration (perceptions of rejection, oppression, and incompetence) on days they are confronted with negative acts and that daily emotional support buffers the impact of direct negative acts (humiliation, physical intimidation) on frustration of the needs for competence and relatedness at the daily level. As such, the results of the present two-sample study provide a better understanding of the boundary conditions under which exposure to negative acts may result in psychological costs by identifying emotional support as a key resource in the workplace that can offset the immediate harmful effects of certain negative behaviors.
