Research has clearly shown the relationship between subjective well-being and work performance, even though there is debate over the causality of that relationship (i.e., does subjective well-being cause higher work performance or does greater work performance lead to subjective well-being?). Regardless, researchers and practitioners would agree that having employees who are productive and have high subjective well-being is valuable. The purpose of this article is to review research in this area and to discuss strategies for promoting well-being at the workplace.
