Today the Bureau of Labor Statistics released new data on union membership for 2013. The data show women’s union membership held steady in 2013 after dropping sharply the year before – and that’s a relief for women seeking better wages and equal pay.

NWLC analysis reveals that the wage gap among union members is half the size of the wage gap among non-union workers and female union members earn over $200 per week more than women who are not represented by unions—an increase that represents a larger union premium than men receive.
The wage gap among union members is half the size the of the wage gap among non-union workers.

Among union members, women working full time are typically paid 90.6 percent of what their male counterparts are paid – a wage gap of 9.4 cents.
Among non-union workers, women working full time are typically paid 81.3 percent of what their male counterparts are paid – a wage gap of 18.7 cents.
The wage gap among union members shrunk by 2.6 cents between 2013 and 2012 (to 9.4 cents from 12.0 cents) – for non-union workers it was virtually unchanged (18.7 cents in 2013, down 0.5 cents from 19.2 cents in 2012).
