, the way followers understand their role is crucial. For example, some forms of (unethical) leadership only take effect when employees internalize the follower role (DeRue & Ashford, 2010) and embody this role in a way that contributes to (unethical) leadership (Carsten, & Uhl-Bien, 2013; Morrison, 1994). Employees use roles such as leader and follower as cues to structure their expectations about the adequate behavior of people who occupy specific positions (Carsten, Uhl-Bien, West, Patera, & McGregor, 2010; Ilgen & Hollenbeck, 1991). Social-cognitive approaches to leadership (Lord & Maher, 1991) showed that when constructing these roles, employees draw on their cognitive structures and schemas regarding traits and behaviors of leaders and followers, that is, implicit leadership and followership theories (ILTs and IFTs; Shondrick & Lord, 2010; Sy, 2010). More recently, conceptual papers (Epitropaki, Sy, Martin, Tram-Quon, & Topakas, 2013; van Gils, van Quaquebeke, & van Knippenberg, 2010) suggested that ILTs and IFTs also influence how people interpret their own roles. What followers (implicitly) associate with their role should thus influence the nature of their contribution to a broad range of organizational outcomes, including (un)ethical leadership (Carsten & Uhl-Bien, 2013; Parker, 2007). Considering followers' implicit theories seem to be particularly promising in order to understand when and why they contribute to unethical leadership in ambiguous 5296J LOXXX10.1177/1548051817705296Knoll et al.Knoll et al.
