Are we working too much?

According to a recent study, when women work more than 34 hours per week and men work more than 47 hours a week, they were more likely to show signs of mental illness and symptoms of nervousness and depression. The reason for the gender gap seems to stem from the fact that women are also far more likely to spend time doing domestic chores and caretaking at home.
A case study of nurses that worked only 6 hours per day instead of the North American standard of 8 hours per day concluded that those employees working only 6 hours per day reported feeling happier and was less prone to taking time off for illness.
While it may seem counter-intuitive, working less may actually increase productivity and employee engagement.
