“…A positive work climate (e.g., autonomy and leader's support) can increase employees’ work effort while a negative work environment (e.g., co-worker's shirking) can obstruct those (Morris, 2009). Workplace ostracism, being a toxic social behaviour and an element of hostile work environment (Ferris, Brown, Berry, & Lian, 2008), can adversely affect important individual and organizational outcomes (Hitlan, Kelly, Schepman, Schneider, & Zárate, 2006b; Ferris et al, 2008; Lustenberger & Jagacinski, 2010; Leung, Wu, Chen, & Young, 2011; O'Reilly, Robinson, Berdahl, & Banki, 2014; Ferris, Lian, Brown, & Morrison, 2015; Fatima, 2016; Ferris, Yan, Lim, Chen, & Fatimah, 2016; Wu, Liu, Kwan, & Lee, 2016; Zheng, Yang, Ngo, Liu, & Jiao, 2016; Chung, 2018), including work effort (Türkmen, Doğan, & Karaeminoğulları, 2016).
