Three types of investment in work
The study distinguishes three types of heavy investment in work: toxic over-investment (or workaholism), work engagement and affective organizational commitment.
Workaholism is defined as addiction to work, characterized by “constant internal pressure and obsessive thoughts focused on work-related tasks,” whereas work engagement is a positive state of mind associated with vigour, enthusiasm and concentration. Lastly, affective organizational commitment refers to an emotional attachment to the organization itself.
The study found a connection between these types of investment in work and workers' self-concept. “In our research, a tendency to define oneself in terms of a collective self—in other words, in terms of membership in a social group—was a predictor of all three forms of heavy investment in work,” Afota said.
By contrast, an individualistic self-concept correlated only with workaholism.
“Workaholism is mainly motivated by darker, less positive goals, such as the need to prove one’s worth, both to oneself and to others,” Afota said. “The problem is, it never ends, and ultimately becomes destructive.”
The results of the study show that the different types of heavy investment in work have contrasting effects.
“Workaholism has only negative effects,” said Afota. “The data show that it leads to an increase in the number of hours worked, work overload and a risk of depression and emotional burnout.”
On the other hand, work engagement is not associated with work overload and protects against depression and burnout.
“This finding challenges the conventional wisdom that organizations benefit from employing people who work long hours,” Afota noted. “In fact, it’s not necessarily a good sign.”
There was no statistically significant correlation between affective organizational commitment and the mental-health indicators used in the study.
