When work becomes an obsession, compulsive behaviours develop that can be harmful and even death-producing. As in hoarding money, gambling, sex or any other process addiction, the act itself (working) loses its intrinsic meaning. Although the line between simple overwork and an unhealthy addiction to work is tenuous, it is fairly easy to tell when one has crossed it. The workaholic uses work to avoid dealing with inner and interpersonal life.
Work has historically been viewed as a tedious necessity. But our obsession with work shows how a neoliberal philosophy has crept into every facet of our lives.
No one ever changed the world on 40 hours a week. (Elon Musk)
