This study investigated the influence of work engagement and self-efficacy on the job satisfaction of secretaries in public institutions, Lagos State, Nigeria. Three research questions were raised, and three null hypotheses were tested at the 0.05 level of significance. Three related theories were reviewed: Deci and Ryan’s job satisfaction theory, Kahn’s work engagement theory, and Bandura’s self-efficacy theory. This study adopted a survey design for a population of 546 secretaries. The sample size was 231 using the Taro Yamane formula [n = N/(1+N*(e)^2)], and the stratified sampling method was used to select participants in each of the institutions. Data were primarily sourced through a validated questionnaire. The data obtained were subjected to Cronbach’s alpha reliability test, which yielded coefficients of 0.699 for job satisfaction, 0.763 for work engagement, and 0.839 for self-efficacy. Out of 231 expected responses, the researcher successfully obtained 184 questionnaires. The obtained data were analyzed using both the descriptive statistics (frequency, percentage, mean, and standard deviation) and inferential statistics (linear and multiple regression at 0.05 level of significance). The combined result [R 2 = 0.666; F- value of 50.921; p-value of 0.000] revealed that both work engagement and self- efficacy significantly influenced the job satisfaction. The work engagement’s result [B = 0.651, p <0.001] contributed 65.1% to the job satisfaction of secretaries, while self-efficacy's result [B = 0.323, p <0.001] contributed 32.3%. These findings suggest that secretaries with a strong sense of fulfillment are more to experience job satisfaction. The study concluded that work engagement and self-efficacy positively influence job satisfaction of secretaries. It was recommended that management should develop comprehensive programs that would focus on creating an environment where secretaries feel engaged and capable in their roles.
