Do labor unions offer the best protection for the worker? Published by the Acton Institute, Liberating Labor questions the assumption that Christian social teaching unequivocally endorses all forms of trade unionism.

This monograph offers the first rigorous-yet accessible-economic analysis of labor unions and the labor market that takes into account the Christian understanding of labor.
