New research has found that only one day of work per week is required for “optimal well-being.” It is understood that unemployment negatively impacts an individual’s sense of well-being and purpose. A study conducted by sociologists, who surveyed over 70,000 people in the UK, suggests that in order to achieve the benefits associated with working, one only needs to engage in work for one day each week. Additional work has not been found to be associated with greater benefits.
