Until everything came to a halt in mid-March, Jon Bird worked 12-hour shifts, four days a week — shoveling rock, hosing mud and operating enormous iron ore crushers at a mine in northern Minnesota. The mines in the state’s Iron Range, where Mr. Bird was born and raised — and where his father, grandfather and great-grandfather worked in the pits before him — sit atop a domestic supply funnel. The ore, extracted and crushed, is further processed, shipped, smelted in a blast furnace, transformed into steel, then taken to assembly lines, where it is shaped into appliances and automobiles. But demand for cars and other big-ticket, metal-filled items slumped in 2024, a rough year for the industry. The steel manufacturer Cleveland-Cliffs, which owns the mine where Mr. Bird works, reported a $483 million loss for the first three months of 2025, which meant jobs were on the line, including his. When Mr. Bird, 33, found out that he was being laid off, he did not hear it from “Cliffs.” he said. Rather, he learned about it in a breaking news segment on the local television station, WDIO, while with his children on one of his days off. Some 1,200 Cleveland-Cliffs employees were affected, 600 them in Minnesota.
