“…This finding is also in line with previous empirical findings at individual analysis, which proposed that social exchange perspectives (i.e., POS) (e.g., Saks, 2006), and supervisory support have a positive influence on employee work engagement (e.g., Menguc, Auh, Fisher, & Haddad, 2012), and job engagement (e.g., Sze & Angeline, 2011). At individual level analysis, the relationship between POS and job satisfaction has been empirical examined by previous studies on a variety of research contexts (e.g., Ambrose & Schminke, 2009;Baranik et al, 2010;Begley et al, 2006;Erdogan & Enders, 2007;Loi et al, 2009;Rhoades & Eisenberger, 2002;Riggle et al, 2009). However, at cross-level analysis, this relationship is confirmed by this study.…”
