Slow economic growth and cost reduction have caused a global increase in employment insecurity. For university students in the process of preparing for employment, these conditions can be a source of enormous stress. The effort to improve the employability of university students who experience difficulties in seeking a job and developing a career, therefore, becomes consequently meritorious. In order to provide new findings of the key antecedents affecting employability, this study investigates the dynamics of work volition and career adaptability. Employability is predicted by integrating career adaptability, which originated in career construction theory, and work volition, which originated in the psychology of working framework. To test the research hypotheses, survey data were collected from 251 students registered at three universities in South Korea and analyzed using a structural equation model and Hayes' process macro. Results indicated that the direct effect of work volition on employability and its indirect effect through career adaptability were significant. Next, the mediation effect of career adaptability between work volition and employability was varied positively by work volition. These results provide practical implications for efforts aimed at increasing the employability of university students and, as such, present a foundation for contribution to ensuring sustainable employability.Sustainability 2019, 11, 7089 2 of 16 for individuals as well [7]. Such changes in the corporate environment demand a more flexible labor market, which in turn necessitates individuals transform their perception of what a career is.

In academic research (e.g., [9,11,12]), sustainable employability refers to one's capacity to maintain a lifelong stable state of employment preparedness. The concept of employability refers to the capability of an employee, not employer, and it can be understood as describing those characteristics or competences of an individual that makes employment feasible [13]. In other words, employability is the ability to exploit one's own potential to maintain sustainable employment security [14], and it refers to long-term career success [15].Although the employability of university students has become imperative, universities do not provide adequate programs enhance employability. To address this apparent oversight, this research aims to investigate work volition and career adaptability as antecedents for strengthening the employability of university students...
