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.
