The 12 hardest-working cities in the world

Online business-to-business marketplace Expert Market has put together a ranking of the global cities where people clock in the most hours worked each year and have the worst so-called work-life balance.

The site compiled information on the biggest, most important cities globally, then ranked them by the average total hours worked each year, using data from Swiss banking group UBS.

We've divided the figure by 52 to give you an idea of how much you'd have to work all year to compete. (This calculation discounts holidays taken in the year.)

Workers in each city on the list work more than 40 hours a week on average, with people in the top-ranking city racking up more than 50 hours.

If that doesn't sound like a lot, remember that our list discounts holiday. It also includes both full-time and part-time jobs, which brings down the average. By comparison, workers in London clock 33.5 hours a week, and those in New York average 35.5.
