"WORKINGMAN’S DEATH is an unflinching portrait of the state of manual labor in the 21st century. 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. Today’s manual laborers are no longer celebrated with hymns of praise."
