This research aims to study the perceived levels of supervisory support, perceived self-efficacy, and work performance of operational-level employees, as well as the effects of these factors on the work performance of employees at the Provincial Electricity Authority in Saraburi Province. The research is quantitative, using questionnaires to collect data from 231 operational-level employees selected using purposive sampling. Data were analyzed using descriptive statistics, including frequency, percentage, mean, and standard deviation, and inferential statistics using multiple regression analysis.
The results showed that perceived supervisory support and perceived self-efficacy were at the highest level overall, while work performance was at a high level. Supervisory support in terms of assistance and care, encouragement to achieve goals, and appreciation of work had a positive impact on work performance. Receiving fair treatment did not have a significant impact. Regarding self-efficacy, learning from the success stories of others and physical and emotional well-being had a positive impact on work performance, while past success stories and social influence did not affect work performance.
