Tough jobs put focus on workers in S. Korea

GEOJE, South Korea - Park Cholhee was working the holiday shift at Samsung Heavy Industries' Geoje shipyard on Labor Day, 2017, when a giant crane collided with another and crashed to the ground, killing six people, including Park's younger brother.

"It was as if a bomb was dropped," Park said. "Bodies were too mutilated to describe."

Park and his brother Sung-woo were among nearly 1,500 subcontracted employees - 90 percent of the shipyard workforce that day - building an oil and gas platform for French energy giant Total.
