64% support labor unions

CNN -According to a recent Gallup poll, 64% of Americans approve of labor unions. That's a five-year high, and the third-highest approval number since 1970.However, actual union membership rates are relatively low. Data from the Bureau of Labor Statistics reveals the general union membership rate for 2018 was 10.5%, which is about even with the numbers from 2017. However, that percentage represents a precipitous overall decline in union membership since comparable data was first released in 1983. That year, more than 20% of workers belongs to a union. Over time, that number has dropped steadily by almost half.
