Abstract:
This study aimed to examine the level of work motivation among personnel at the Northern Petroleum Development Center, Department of Energy, Royal Thai Armed Forces, using Herzbergs Two Factor Theory as the conceptual framework. Data were collected through a questionnaire from a sample of 229 individuals selected using quota sampling. Descriptive statistics, including frequency, percentage, mean, and standard deviation, were used for analysis. Inferential statistics included the t-test for comparing differences between two groups, and One-way ANOVA for comparing differences among three or more groups. The results revealed that among the motivational factors, career advancement had the lowest average score. Personnel expressed a need for a transparent promotion process and opportunities for skills development. Development-related factors, such as training and further education, were rated at a moderate level. For hygiene factors, which help prevent dissatisfaction, the organization showed strengths in working conditions and team relationships, with particularly high scores in health benefits and lunch provisions. However, compensation was identified as an area needing improvement, receiving the lowest mean score due to perceptions of misalignment with performance and a lack of fairness. Additionally, organizational policies were seen as needing more employee participation in the decision-making process. The study also found significant differences in motivation based on age, work experience, and job position. Younger personnel (under 25 years old) and those with less than five years of work experience reported higher levels of motivation than those aged 4054 years and with 1115 years of experience. These differences were especially prominent in areas such as peer recognition, support from supervisors, and opportunities for self-development through training or further education. In terms of job positions, civil servants reported higher motivation levels than permanent employees and personnel of the Department of Energy, particularly in areas such as career advancement, recognition, job achievement, job security, clear welfare systems, and positive relationships with supervisors and coworkers.
