Factors Influencing Employee Loyalty in PTT Gas Stations in Mueang District, Ubon Ratchathani, Thailand

Abstract
This study investigates two primary objectives: (1) to assess the levels of work motivation, individual needs, and organizational loyalty, and (2) to examine the influence of work motivation and individual needs on organizational loyalty among employees at Petroleum Authority of Thailand (PTT) gas stations in Mueang District, UbonRatchathani, Thailand. The study employs a quantitative research approach, utilizing structured questionnaires with a validity score of 0.85 and a reliability score of 0.89. The sample comprises 210 employees from PTT gas stations. Descriptive statistics, including frequency, percentage, mean, and standard deviation, were used alongside multiple regression analysis to test the hypotheses. The findings indicate that most respondents were male (66.70%), aged between 21–29 years (80.50%), single (46.20%), held high school education (65.70%), and earned less than 9,000 baht per month (62.90%). The levels of work motivation, individual needs, and organizational loyalty were generally high. Among motivational factors, intrinsic factors scored higher than extrinsic factors. Individual needs were ranked from highest to lowest as follows: social and belonging needs, physiological needs, self-actualization, safety and security, and esteem needs. Organizational loyalty dimensions revealed that perception-related factors ranked highest, followed by emotional attachment and behavioral expression. The hypothesis testing identified five significant predictors of employee loyalty: esteem needs, physiological needs, motivational factors, self-actualization, and social and belonging needs. Maintenance factors and safety and security needs, however, were not significant at the 0.05 level. Keywords - Employee Loyalty, Work Motivation, Human Resource Management, Petroleum Retail Industry
