John Beverly, 42, a Viet Nam veteran, suffers from posttraumatic stress disorder, which includes sudden flashbacks of battlefield terror. Last week two administrative-law judges in Wisconsin awarded Beverly $85,700 in worker's compensation after finding that co-workers at the Miller brewery in Milwaukee preyed on him from 1981 to 1983 by taunting him with loud noises. Beverly claimed that employees popped milk cartons, broke beer bottles and even set off fireworks to see his reaction. Helpless in the grip of the disorder, he would throw himself to the floor. Eventually he became so anxious, the judges found, that he could no longer hold a job. The Miller company, which would pay the penalty, plans to appeal the ruling.
