“…For example, Udin and Yuniawan (2020) have found a positive relationship between the Big-5 personality traits (extraversion, agreeableness, openness, conscientiousness, and neuroticism) and OCB, similar to the earlier study of Organ et al (2006) who have also found the same relationships, particularly between conscientiousness and OCB. As for leadership styles, studies in literature were able to demonstrate that transformational (Khaola & Rambe, 2020), transactional (Zabihi et al, 2012& Daouk et al, 2021 as well as strategic leadership (Gusmão et al, 2018) have been shown to be determinants of OCB. Continuing with more recent studies, employee engagement (Geng et al, 2016), goal clarity (Caillier, 2016), employee motivation (Joo & Jo, 2017) -and specifically extrinsic motivation (Shaaban, 2018) -, employee empowerment (Li et al, 2017), emotional intelligence (Turnipseed, 2018), organizational learning (Gusmão et al, 2018) and ethical work climate (Teng et al, 2020) were all found to be predictors of OCB.…”
