The environment of workplaces, the performance of the employee, and the different effects of the withdrawal behaviors are a common interesting area for many researchers. The scientific journals have published several aspects of the employee's behavior in the work environment to present the most im-portant effects on it. This study organically combines the literature-defined concepts of behavioral patterns with a case-based analysis. We connect performance and employee behavior to the cognition of human behavior, human mindset, and the process of decision-making. The focal point is the concep-tual triad of employee turnover, commitment, and satisfaction. It has been investigated from the trust approach because this is the environment in which we can set up a pattern of employee mindset at work that can help the company in the strategic decision-making process. 73 dismissal cases of manual workers from manufacturing companies served as the basis of inves-tigation. Instead of the common Likert scale in surveys, this study modelled the human mindset based on logical correlations with help of an expert system that can provide a deeper insight into the human decision logic. The nov-elty of the research method creates an opportunity to represent information more nuanced than statistical methods. The paper discusses the potential implications of the model in terms of employee turnover and human decision-making priority.
