“…Among the components of commitment, affective commitment has attracted the most research attention because it is associated with important organizational outcomes, such as turnover, job performance, and citizenship behavior (Cooper-Hakim & Viswesvaran, 2005; Meyer, Stanley, Herscovitch, & Topolnytsky, 2002). Among other entities to which commitment can be directed, the supervisor has emerged as an important one as affective commitment to the supervisor (ACS) has been found to contribute unique variance in work outcomes over and above affective commitment to the organization (ACO; e.g., Askew, Taing, & Johnson, 2013; Becker, Billings, Eveleth, & Gilbert, 1996; Becker & Kernan, 2003; Cheng, Jiang, & Riley, 2003; Stinglhamber & Vandenberghe, 2003; Vandenberghe, Bentein, & Stinglhamber, 2004). The reason for this is that, even if they are nested within, and partly act on behalf of the organization (Coyle-Shapiro & Shore, 2007; Mueller & Lawler, 1999), supervisors are more concrete, visible, and proximal (Becker, 2009) than the organization and, hence, act as powerful referents for employees.…”
