In recent years, there is increasing research interest in workaholism (Clark, Michel, Zhdanova, Pui, & Baltes, 2014). However, if one has read research articles on this topic (e.g., Aziz & Zickar, 2006; Fassel, 1990; Machlowitz, 1980; Mudrack & Naughton, 2001; Ng, Sorensen, Feldman, 2007; Oates, 1971; Porter, 1996; Robinson, 1998; Schaufeli, Taris, & van Rhenen, 2008; Scottl, Moore, & Miceli, 1997; Snir & Harpaz, 2012; Spence & Robbins, 1992; Sussman, 2012), it is not difficult to notice that there is lack of consensus in definition of workaholism (Clark et al., 2014). Because of the situation of multiple definitions for workaholism, conclusions can not be clearly drawn from different research, because there is no guarantee as to whether the differences among these research originate from differences between research per se, or just from different definitions that researchers adopted, where the latter means that basically researchers are measuring different things. For example, according to Ng et al. (2007), workaholics should have career satisfaction and success; however, this would not be the case according to Spence and Robbins (1992). If someone looks at the definitions of workaholism these researchers used in their research, it will be clear why they would not agree with each other. In the definition given by Ng et al. (2007), workaholics enjoy working, whereas, in the definition provided by Spence and Robbins (1992), they do not. This is, suffice it to say, troublesome.
