Naked Capitalism:
There is a common myth that unions hurt productivity, supposedly because they impose work rules that make their employers less efficient. The evidence from industrial relations studies does not support this myth. A broad study of the economics literature found “a positive association [of unions on productivity] is established for the United States in general and for U.S. manufacturing” in particular (Doucouliagos and Laroche 2003, 1).1 And as the second chart below reveals, international comparisons suggest that high productivity and very high union density are entirely compatible.
