This suggests that loving your work can mitigate some of the risk associated with obsessing over it. We also found that engaged workaholics reported having more resources at home and at work compared to non-engaged workaholics. Engaged workaholics reported receiving more social support (e.g., advice, information, appreciation), from their supervisor, co-workers, and their spouse, than their non-engaged counterparts. They also scored higher on communication skills, time management skills, and general work skills, and they reported much higher intrinsic motivation for work than non-engaged workaholics.
