STEVEN GREENHOUSE covered labor at the New York Times for 19 years. When we last spoke in the early days of the Biden administration, workers’ share of income had slid to its lowest level since the 1940s and the percentage of workers in unions was the lowest in over a century. But unions are winning these days – winning contracts, winning strikes when necessary, and perhaps most critically in the big picture - winning popular support, especially among young people.
