The purpose of this paper is to determine if a firm?s environment factors, job-related factors, and employee-related factors affect employee performance. Using a descriptive and causal research design, AA employees were asked to complete an online survey using the questionnaire adopted from Diamantidis and Chatzoglou (2018). The mean was used to summarize the respondents' perceptions of the variables, while simple and multiple linear regression were used to test the hypotheses formulated. According to the findings, job-related and employee-related factors have a significant effect on employee performance, whereas firm environment factors have no significant effect on employee performance. Furthermore, firm environment and job-related factors significantly affect employee-related factors, whereas firm environment has a significant effect on job-related factors. The findings will serve as a starting point to reexamine AA Manufacturing's traditional work policies and expectations, allowing researchers to come up with a CAPSTONE Project that can be discussed with executives.
