The Fourth Industrial Revolution (Industry 4.0) gives impetus to educational reform. Education experts have recently recognised the benefits of using technology in learning and teaching. They believe that innovations will shape Education 4.0 and that teachers will need to be prepared to build creative learning environments that support student creativity. Thus, the main purpose of this paper is to examine the relationships between teamwork, principal support, humor, and innovative work behaviour (IWB) among teachers. This study was conducted using a questionnaire, with a sample size of 354 school teachers in Malaysia. Multiple linear regression analysis has shown that teachers with high quality of teamwork and principal support were more likely to report innovative work behaviour. The findings indicated that teachers who frequently use humour can create more innovative behaviour. This paper can help managers and policymakers in the education sector, to develop a better understanding of these aspects, and their influence on teachers' innovative behaviour at work. In doing so, it would be helpful if teachers learnt effective procedures for innovative behaviour in class, via means of teamwork, humor, and principal support, to enhance their educational efforts. It is, therefore useful to establish university courses for pre-service teachers, focusing on new collaborative innovation strategies to encourage creativity and innovation in educational settings, and to apply collaborative creativity exercises in the classroom.   Keywords: Teamwork quality, Humor, Principal support, Teachers, Innovative work behavior, Malaysia

According to the Malaysian Ministry of Education's (MOE) national education model, the education system is meant to produce people who are knowledgeable, competent, and able to contribute to the nation's improvement. Educators must demonstrate unique actions to nurture their students seamlessly and systematically, according to the idea. The purpose of this paper is to present an empirical study that looks at the impact of humor and teamwork on teachers' innovative behaviors in Malaysian secondary schools. The goal of this study was to find out how engaged teachers are in innovative behavior (IB) in terms of idea generation (IGEN), idea promotion (IPROM), and idea implementation (IIMPL), as well as to look at the relationship between humor (HUM) and teamwork (TW) and IB (IB). This quantitative study was conducted using a survey of 354 selected respondents. The respondents were selected from 4,319 teachers in two different zones in the state of Selangor by using the stratified random sampling technique. The findings suggest that there is a good level of teachers’ engagement in idea generation, and a moderate level of idea promotion and idea implementation behavior. The findings also reveal that humor and teamwork are positively and significantly correlated to innovative behavior. Overall, this study provides a better insight into how humor and teamwork contribute to teachers’ innovative behavior.
