Thehospitality industry is extremely competitive, and employee innovative behaviour plays an essential role in determining whether hotels survive, grow, or achieve a competitive advantage. This research implements structural equations modelling via SMART-PLS3 to analyse the 504 valid questionnaires to assess the theoretical framework and identify the factors that influence employee innovative behaviour. This paper focuses on five-star hotels in Egypt which use an innovative approach to evaluate the influence of Perceived supervisor support (PSS) through supervisor trust (ST) and Leader-Member Exchange (LMX) on employee innovative behaviour (EIB). The investigation depicts the relations among the different variables of the study and has enhanced our understanding of EIB. Results indicated the PSS predicted LMX significantly, which in turn influenced the ST. PSS has also been found to have an indirect impact on the EIB through LMX and ST. The variation clarified by the proposed research model in the EIB is 32.3%.
