The purpose of this study is to examine the relationship between meaningful work and organizational citizenship behaviour. This study employed a quantitative approach using a cross-sectional survey strategy to obtain data from 395 teachers in Malaysia. Proportional stratified sampling was applied to ensure equal probability for respondent selection. Data analysis included descriptive statistical analysis and structural equation modelling analysis. The results indicate that the path coefficient from meaningful work to organizational citizenship behaviour was significant and in an expected positive direction. The use of a self-administered questionnaire and single-source data may lead to concerns about bias. The cross-sectional survey employed in this study may also contribute to data inaccuracy. The findings of this study imply that principals should assist teachers to engage with meaningful work in order to motivate them to exhibit organizational citizenship behaviour (OCB) which involves going above and beyond their formal job requirements. Thus, the results of this study offer insight on the importance of teachers' experiences with meaningful work and enhanced OCB. These findings also contribute to the limited literature exploring the relationship between meaningful work and OCB in educational organizations in the Malaysian education context.
