If you don't count Baghdad, Pyongyang (North Korea) or Harare (Zimbabwe) -- cities affected by war or economic sanctions -- which cities are the most challenging places to work in?
Business Week asked a New York-based human resources consultancy, ORC Worldwide, to provide a list of the toughest cities in the world, outside the U.S., Canada and Western Europe. ORC listed 55 cities "... based on a set of criteria that includes levels of pollution, disease, political violence, and availability of goods and services."
What city takes the prize?
The Nigeria commercial capital, Lagos.
The rest of the top five are: Jakarta (Indonesia), Riyadh (Saudi-Arabia), Almaty (Kazakhstan) and Mumbai (India).
