Today's manual laborers are no longer celebrated with hymns of praise. They must be content with encouraging one another that backbreaking work is better than no work at all. In the Ukraine, a group of men spend long days crawling through cramped shafts of illegal coal mines. Sulfur gatherers in Indonesia brave the smoky heat of an active volcano and the treacherous trip back down. Blood, fire and stench are routine for workers at a crowded open-air slaughterhouse in Nigeria. Pakistani men use little more than their bare hands to dismantle an abandoned oil tanker for scrap metal. Steelworkers in China fear they could be a dying breed. Five portraits of heavy manual labor, increasingly less visible in our technological 21st Century.
