Samsung Electronics has said it failed to create a safe working environment at its computer chip and display factories. The South Korean technology further apologized for the sickness and deaths of some of its workers.
Earlier, the company and a group representing ailing Samsung workers had agreed to accept compensation terms suggested by a mediator and to end a highly-publicized standoff that went on for more than a decade.
The company failed to "sufficiently manage health threats" at its semiconductor and liquid crystal display manufacturing lines, Samsung's device solutions chief Kinam Kim said.
The civic movement against Samsung began in 2007 when taxi driver Hwang Sang-gi refused to accept as settlement after his 23-year-old daughter died of leukemia after working at a Samsung factory.
