Fear is a powerful emotion that seems incompatible with effective functioning and well-being in organizations. This assumption bears out in the relatively small amount of existing research on fear in the workplace and a general unwillingness to talk openly about fear at work. Despite any reluctance or attempts at avoiding discussions of fear at work, this basic human emotion has been adaptive in helping people escape, avoid, and face a wide range of threats. Additionally, given the persistent presence of fear in organizations due to the nature of some occupational work, affective events, and organizational climate, it is important to have a broader understanding of where it comes from, its effects, and its outcomes. This chapter explores dual perspectives on fear in the workplace, considering organizational research on functional and dysfunctional experiences and outcomes associated with this emotion. Fear has important implications for emotional well-being, social interactions, and performance, requiring employees and leaders to better understand fear by creating more dialogue about how to regulate and manage it.
