RESUMO
The current study primarily aims to investigate the happiness at workplace (HAW)-innovative work behaviour (IWB) correlation through the mediating effect of organisation citizenship behaviour (OCB) and moderating effect of organisational innovative culture (OIC). Notably, 383 questionnaires were collected from lecturers employed in three local universities in Malaysia and subsequently evaluated using structural equation modelling (PLS-SEM). Based on the study outcomes, HAW positively and significantly affected employees' IWB through the mediating and moderating effects of OCB and OIC, respectively. University directors should establish effective HAW approaches that elevate workers' organisational satisfaction, involvement, and commitment and develop a creative culture that acknowledges and complements innovation. This study, which pioneered the examination of the moderating effect of OIC, (i) filled the literature gap on the HAW-IWB link in emerging nations and (ii) expanded the 'broaden and build' and 'social exchange' theories with concrete proof of the HAW impact on OCB.
