Role conflict, need frustration and supervisor support: a moderated-mediation model of employee voice and silence

Purpose Drawing on the conservation of resources theory, the purpose of this paper is to examine whether role conflict is associated with frustration of employees’ basic needs and whether need frustration is associated with withdrawal in the form of reduced voice and increased silence. This paper also investigates if supervisor support mitigates potential detrimental outcomes of need frustration. Design/methodology/approach In this survey-based study, 201 full-time employees participated. Self-reports regarding voice and silence behaviors at work were collected as were perceptions of role conflict, need frustration and supervisor support. Findings The results of this study support the proposed moderated mediation relationships for both employee voice and silence behaviors. Specifically, need frustration mediates the relationship between role conflict and the two outcome variables. Perceived supervisor support moderates the path between need frustration and both voice and silence behaviors. Practical implications Employees are an organization’s first line of defense against potential accidents, inefficiencies and other organizational crises. When they perceive their needs are not met and they are not supported by their supervisors, employees are likely to seek to protect themselves from further resource loss by withholding feedback even if such feedback may enhance organizational effectiveness and prevent organizational crises. Originality/value Given that voice and silence are not opposites of each other, it is important to study both in a single study, as this study does. This study proposes and tests a heretofore untested explanation for the relationship between role conflict and voice and silence. The authors identify a buffer with potential to mitigate the negative effects of need frustration.
