127 days ago the Teamsters Local 120 called a strike at the Marathon oil refinery in St. Paul Park alleging unsafe working conditions and unfair labor practices. Some 200 workers haven’t returned since.

Marathon says it has rigorous health and safety standards and an exemplary record. Workers say a disaster is all but certain. This week, a 22-year veteran of the refinery explains why he’s so worried and what will get him back to work.
