Climate change is a global phenomenon which effects continue to generate attention. Workers are exposed to many types of climate change related hazards depending on the type of work, geographic region, season, and duration of work time. This study aim to evaluate the effects of climate change on workers with respect to their health, safety and productivity. In this study, data was collected from a total of 200 respondents who were workers across four occupational sectors: agriculture, fishing, construction and food production using well structured questionnaires. There was significant difference between the perceptions of climate impact among the workers in the four sectors from the model final χ2(15, N= 200) = 38.211, p= 0.001 Nagelkerke R2 = 0.186. There was no significant relationship between low productivity and climate change related hazards in workplace, from Omnibus χ2(5, N= 200) 8.642, p= 0.124. The climate change related hazard affected the health and safety which subsequently result in a low productivity by the workers. Increased ambient temperature has more significant effect on the workers in their workplace environment.
