 Support for organized labor, polls indicate, is at a high not seen since the 1960s. Strongest among Generation Z, people in their teens and 20s. Unions have been out of favor for decades. 20% of workers belonged to one in 1983. But by 2020, that number had fallen by half. Even as membership drops, union support is rising. 71% of Americans approve of them. Unions had a difficult time making inroads in the South.
