Abstract:

Human capital is a rare and inimitable strategic resource for businesses to gain sustainable competitive advantage. Thus, it is significant to ameliorate and develop the psychological capacities of employees in showing their performance towards the goals of the businesses. In this sense, the concepts of psychological capital and work engagement, which allow the measurement of the psychological capacities of employees, stand out. The relationship between these two variables has been mostly examined in the relevant literature; however, it has been drawn attention to determine the deficiency of the mediator variable that causes the relationship. Moreover, it has been observed in the literature that these two variables are predicted by positive voice behavior. From this point of view, 375 participants were reached using the snowball sampling technique and the statistical analysis of the obtained data was carried out. As a result of the analysis, it has been seen that psychological capital has a positive and significant effect on work engagement and positive voice behavior. Additionally, it has been determined that positive voice behavior has a positive and significant effect on work engagement. Finally, it has been concluded that positive voice behavior plays a partial mediating role in the effect of psychological capital on work engagement.
