We share the authors' belief that contingent workers play an increasing role among the workforce in general (Desiderio, Djibo, & Price, 2010). As the authors state, the increase of temporary work is primarily due to economic demands. Particularly when confronted with seasonal or economic fluctuations, contingent work may be a means to enhance efficiency and flexibility.For several reasons it is an important issue to address questions related to the specific work situation of temporary workers, who do not hold long-term employment contracts. First, we agree that there are good reasons to challenge the assumption that findings with permanent workers can be easily generalized for the group of contingent workers without further evidence. Second, the authors make an important point when they highlight that contingent work may cause specific risks for the organizations that may compensate potential benefits. The development toward increased use of temporary employment was not primarily initiated or desired by employees. This has raised concerns about the impact of temporary employment on the individual (De Cuyper, de Jong, De Witte, Isaksson, Rigotti, & Schalk, 2008).Actually, the bulk of research in the field of work-related attitudes such as job satisfaction or organizational commitment, and so forth, has been conducted with employees holding regular permanent working contracts. The same holds true for the research that examines the impact of different leadership behaviors on the aforementioned attitudes as well as performance indicators. One of the performance indicators that has gained growing interest is organizational citizenship behavior (OCB), which serves as an umbrella term for a variety of extrarole behaviors. These behaviors have been shown to be favorable for the organization' s performance and success. Moreover, leadership
