“…The current and extensive, body of research has tried to clarify the nomological network, antecedents and consequences of informal learning (Tannenbaum et al , 2010), yet the literature is inconclusive about learning climate and its dimensions as antecedents and OCB as the outcome of informal learning due to the largely anecdotal nature of the research (Cerasoli et al , 2018; Uhunoma et al , 2020, Messmann et al , 2018). The present literature shows that training climate, workplace support, autonomy, feedback and managerial support facilitate informal learning (Noe et al , 2017; Orvis and Leffler, 2011; Zia et al , 2020, 2021a). Some studies also investigated the linkage of informal learning to work outcomes such as engagement, job performance and commitment (Cerasoli et al , 2018; Susomrith and Coetzer, 2019; Yoon et al , 2018), but did not consider OCB when learning climate acted as an antecedent.…”
