Using data from Swiss banking group UBS, the site compiled information on the biggest, most important cities globally, taking into account how many hours per week and per year people work as well as how many days holiday they take, before creating the ranking.
All 13 cities are in Europe, although 12 different countries are represented. France is the only nation where two cities feature, and no British cities make the cut.
Workers in each city work fewer than 33.5 hours per week, with people in the top ranking city clocking just 30.8 a week.
