The Unintended Effect of Perceived Transformational Leadership Style on Workaholism: The Mediating Role of Work Motivation.

Given the apparent magnitude of the problems related to workaholism, the current research was designed to provide evidence about the impact of both personal and organizational variables on determining health-damaging work habits of the employees. This paper presents a study aimed at clarifying the mediating role that work motivation plays in the relationship between the perceived transformational leadership style and workaholism. Based on the Self-Determination Theory and the Job Demands-Resources model, we hypothesized that transformational leadership should be directly related to the lower levels of workaholism, whereas the indirect effect of transformational leadership was expected to increase the levels of workaholism through work motivation of the employees. Two hundred and fifty Lithuanian employees participated in the empirical study. The results confirmed the expected relationship between transformational leadership and workaholism via work motivation showing that the negative role of transformational leadership in workaholism is explained by its positive influence on intrinsic motivation, as well as introjected, integrated, identified regulations, which, in turn, enhance the employees' workaholism.
