The study investigates effect of organisational reward system on employee performance in selected hotels in Lagos Metropolis, Nigeria. The objective was to establish effect of organisational reward system (Recognition, Employee Development, and Benefits) on employee performance (contextual performance, counterproductive behaviour, and adaptive behaviour) in selected hotels in Lagos Metropolis using a survey research design. Two hotels were sampled and used for the study. A total population of 315 employees were investigated with a sample size of 255. In this research, a simple random sampling technique was adopted, and only 204 copies (or 80 percent) of the questionnaire were properly completed and recovered. To determine the link between the variables, the data was examined using the bivariate regression analysis. The investigation revealed that recognition had significant effect on contextual performance in selected hotels in Lagos Metropolis, Nigeria (β = 0.592, t = 12.353, p < 0.05). The finding also revealed that eemployees’ development has a negative and significant effect on counterproductive behaviour in selected hotels in Lagos Metropolis, Nigeria (β = -0.244, t = 6.441, p < 0.05). Also, it was discovered that benefits had significant effect on adaptive performance in selected hotels in Lagos Metropolis, Nigeria (β = 0.399, t = 9.339, p < 0.05). As a result, it was concluded that organisational reward system affected employee performance in selected hotels in Lagos Metropolis, Nigeria. It was suggested, among other things, that hotel management should be intentionally observing employee performance and looking for opportunities to recognize outstanding work achievements and behaviour.
