“Enthusiastic [work] addicts work the longest hours and report less private time out of all the groups identified. This group is significantly male and often within high hierarchical positions. Intrinsically motivated by loyalty, self-development and responsibility, they are satisfied with their salary and do not intend to leave their company. However, this group reports many work/family conflicts.” (Buelens, 2002, p. 64)
