**1. Introduction**

The majority of the world's population works. Therefore, work plays an important role in their lives. For personal development and economic needs, it is the most important factor for people. However, working conditions and the way people approach their work life have a great impact on their quality of life and well-being. According to the literature review, workaholism is increasing rapidly compared to previous years, and thus, it seems that there is an increased interest in workaholism-related issues among researchers% [1–3]. In Norway, the recent study by Andreassen et al. [1] showed that the prevalence of workaholism was at 7.3%, but it may be that the rate of self-workaholism is much higher among the working

population than it was estimated [2, 3]. Therefore, the amount of research associated with workaholism has been increasing in recent years, and the terms "work addiction", "workaholism", "excessively overwork" have been prevalent throughout [4–7]. However, it seems that there is no common consensus about its meaning, which may very well be considered an important public issue in the future; this is because it gradually deteriorates people's health, causing mental and physical health problems, such as coronary heart disease, anxiety, and work-related stress. For a long time now, it has also had a negative influence on people's social lives, including family relationships and work performance—resulting in the decreasing of quality of life and well-being. Workaholics tend to spend most of their time working, leaving aside their social life, which leads to having more family conflicts and a lack of recreational activities [3, 4]. These results can be explained by the fact that they constantly feel stressed and pressured to succeed, physically harming themselves due to their work hours. Beyond that, it has been stated that workaholics are more likely to have obsessive–compulsive disorder, attention-deficit disorder, and hyperactivity disorder, showing that workaholism may be a sign of deeper psychological or emotional problems.

Although much is known about the consequences of workaholism, there is very little information about the source of workaholism [3–5].

Therefore, this review was aimed to examine definitions of "workaholism", the factors affecting the occurrence of workaholism, and the consequences of workaholism.
