The Enthusiasm and Exhaustion of Socio-Economic Organization Workers: Based on the Perspective of Job Characteristics 206 insignificant influences on the dependent variables, but it has significant correlation between the dependent variables. In general, all of the five perceived characteristics of SEO jobs collectively affect workers’ career commitment, career satisfaction, or organizational impact on society. 3.2 Mediating Effect Analysis After including mediating variables (the experienced meaningfulness of work and perceived job stress) in our analysis, we further find that the experienced meaningfulness of work fully mediates the effects of skill specialization, task utility, and task conduciveness on worker career commitment, and the effects of task conduciveness on career satisfaction. We also find that the experienced meaningfulness of work partially mediates the effect of problem solving on career satisfaction. Moreover, task conduciveness positively impacts the experienced meaningfulness of work and job stress, in turn strongly influencing he perceived organizational impact on society. Conversely, the perceived five core job characteristics have no influence on perceived organizational profitability. The above conclusion is in line with the values of nonprofit SEOs. Furthermore, despite the imperfection of our theory framework, based on the viewpoint of meta-thinking, we find two implications of the study. First, the findings show that different job characterstics prime the enthusiasm and exhaustion of workers, which further affect different criteria. Specifically, task conduciveness prime the sense of exhaustion (the perceived job stress) and has an influence on perceived organizational impact on society. On the other hand, skill specialization, task utility, task conductiveness, and problem solving, among others, can prime workers’ enthusiasm (the experienced meaningfulness of work), and in turn influence individual perceptions (such as perceived career satisfaction and career commitment). Second, SEO workers’ psychological states involve both positive-enthusiasm and negative-exhaustion elements, rather than just a simple outlook. 4. Research Limitations Given the nature of their operations, most SEOs are small-sized organizations and often have insufficient workforces. Therefore, insufficient sample sizes may hamper the validity of our findings. Moreover, the study conducts an exploratory factor analysis (EFA). The test ascertains more than one factor. The explained variance of the first factor
