The question that needs to be asked is whether we are more productive and successful with fewer days, or whether work is getting in the way of our success. Statistically, taking more vacation results in greater success at work as well as lower stress and more happiness at work and home. So why aren’t we using more vacation time? At first glance, one might think that a scarcity of jobs or lack of job security might be leading people to believe they always need to be at work. But the data does not support that. During 1982 and 2010, the two years since 1981 with the highest unemployment, people still used an average of 20.9 days of vacation. In 2015 the unemployment rate was 5.3% (it was 9.7% in 1982), and yet 2015 had one of the lowest averages of time off taken in the past 30 years: 16.2 days. There may be lots of reasons for this, but clearly unemployment rate does not directly correlate with time taken off. Get the full story at Harvard Business Review
