This study aimed to determine the influence of work ethics on job performance of employees in local government units (LGUs) in selected municipalities of District IV, Province of Laguna. A total of 203 employees from different LGUs were surveyed using a self-administered questionnaire. The study utilized a descriptive-correlational research design and statistical tools such as mean, standard deviation, One Way ANOVA and Pearsons correlation coefficient were used to analyze the data gathered. Results showed that the level of work ethics among employees in LGUs was verbally interpreted as very influential in terms of responsiveness to the public, nationalism and patriotism, commitment to democracy, and simple living. On the other hand, the relationship between the employees profile and their work ethics was found to be insignificant. Furthermore, the study revealed a significant positive relationship between work ethics and job performance. The results imply that employees with high work ethics tend to have better job performance. Based on the findings, the study recommends that local government units should conduct regular trainings and workshops for employees to enhance their work ethics and to improve job performance. This study provides valuable insights for LGUs in improving the performance of their employees through the development of their work ethics.
