The Crane & Dock Supervisor Jacket is the distinguishing garment of anyone running a shift at GLMZ's lakefront cargo terminals — a role that involves managing automated crane systems, human crews, radiation-flagged cargo protocols, and the constant weather off Lake Michigan. The jacket is a heavyweight canvas-shell design with a Dyneema-reinforced outer layer and a removable thermal lining for the winter corridor season. High-visibility panels — retroreflective gold-orange — run along the shoulders and forearms, and a GPS-linked beacon chip is embedded in the right collar point, standard for anyone working in active crane swing zones. The HarborGrid Collective patch on the left arm indicates union seniority tier; supervisors have earned the gold-bordered version. Pockets include a sealed document pocket rated for spray exposure and a dedicated slot for the supervisor's radiation dosimeter clip.
