“…In the selected papers, sharing took place at all managerial levels (top, middle and first-line), and all papers but two could be categorised according to the organisational level of the sharing managers 4 (see Figure 5). Studies of first-line managers were the most common (Thomson and Blackmore, 2006; Rosengren and Bondas, 2010; Eckman and Kelber, 2010; Döös et al, 2018a; Court, 2003; Court, 2004b), followed by studies of shared leadership at the top level, that is, CEOs and directors (Voss et al, 2006; Reynolds et al, 2017; Reid and Karambayya, 2009; Fischbach et al, 2007; Cater III and Justis, 2010). A few studies only focussed on sharing between middle managers (Clausen et al, 2017), a few on both middle and first-line (Thude et al, 2017), and a few on all three levels (Steinert et al, 2006; Saxena et al, 2018; Klinga et al, 2018).…”
