The aim of the study was to determine the effects Web-Bulb Globe Temperature(WBGT) on the operators' performance at Malaysian automotive industry. One automotive assembly factory had been chosen as a subject for the study. The subjects were workers at the assembly section of the factory. The environment examined was the WBGT of the surrounding workstation area. One set of representative data, which is the WBGT (°C) and production rate were collected during the study. The production rate data were collected through experimental procedure by executing the motion and time study. Meanwhile the WBGT was measured using Quest Thermal Environment Monitor equiptment. The correlation and linear regression analysis were conducted in order to obtain the relationship between the effects of WBGT to the worker performance. The results from the correlation analysis revealed there is a weak negative relationship between the WBGT and productivity of the workers. The linear regression analysis further reveals that there is a linear equation model with negative slope to describe the relationship of WBGT and workers performance for the assembly section involved. The linear regression line obtained is Y = -13.3X + 425.
