Irregular schedules raise risk of injury for miners working long hours

Researchers from the University of Illinois at Chicago found that injured miners who worked shifts longer than 9 hours tended to have irregular schedules or less than two years on the job. Long work shifts were associated with a 32% increased risk of injury resulting in death and a 73% increased risk of multiple worker injuries.
