union workers make $200 a week more
than non-union

In 2011, among full-time wage and salary workers, union members had median usual weekly earnings of $938, while those who were not union members had median weekly earnings of $729. In addition to coverage by a collective bargaining agreement, earnings differences reflect a variety of influences, including variations in the distributions of union members and nonunion employees by occupation, industry, firm size, or geographic region.
