The current study examined job content plateaus, which occur when employees perceive a lack of future challenge or responsibility in their jobs. Although previous research has indicated that job content plateaus are related to poor job attitudes and outcomes, few studies have examined mediators of these relationships, a critical step in theory development. In this study, we tested a mediation model to examine the outcomes of job content plateaus among a sample of 118 hospital employees in Kenya. Job content plateaus were negatively related to job satisfaction and organizational citizenship behaviors directed at individuals (OCBIs). Job satisfaction was positively related to OCBIs and organizational citizenship behaviors aimed at organizations (OCBOs) and mediated the relationship between job content plateaus and OCBIs and OCBOs.
