Innovative behaviour (IB) refers to the process of developing, generating, applying or promoting new ideas by employees to increase job performance. Today, the rapid social and technological changes in our environment highlight the significance of IB of employees and especially for teachers. Thus, this paper aimed to develop a conceptual framework of factors influencing innovative behaviour of teachers in secondary schools. The research was explored through critical related literature analysis. Findings were presented in form of descriptive analysis, which shows that workplace happiness (WP), organisational climate (OC), affective commitment (AF) and transformational leadership (TFL) play a direct role in affecting innovative behaviour. The paper concludes that WP, OC, AF and TL have a positive impact in creating the essential conditions to encourage teachers to show IB in schools.
