By working, people maintain their motivation to work and gain a sense of daily fulfillment and self-understanding. the aim of this study is to clarify how employees' interest and motivation, considering their personal temperament and work environment, lead to goal achievement, and develop a scale to measure sustainable work styles. The data from 1,693 subjects out of 1,946 were analyzed. Cronbach's coefficient was used for reliability verification. Content validity and construct validity were also used to verify the validity of the scale. Among the participants, 97.7% were women. As a result of the analysis, the reliability coefficient for the entire scale was 0.967. The structural equation models showed that the fit of the model is good with RMSEA of 0.067, GFI of 0.926, and CFI of 0.927. Regarding the indicator variables in the path diagram, the indicator for "Relationships with co-worker" had a moderate correlation with "Work environment". there was a weak causal relationship between "Personality", "Concept formation", "Interest", and "Motivation" in "Relationships with co-workers". Despite these weak causal relationships, the goodness of fit of the model in this study met the criterion value, indicating that it was conceptually valid. This research emphasizes evaluating how employee satisfaction is triggered and how it can lead to the achievement of work goals.
