For what it's worth, the AFLCIO doesn't list themselves in their list. Their CEO, Richard Trumka, makes over $300K/year... More than 5x the average worker, and he got a $50K raise in the past 3 years while his memberships incomes lagged.

How much does the Economic Policy Institute pay him to be on the board of directors?

How much is his net worth?

How is it possible that the AFL/CIO represents their membership, when 100% of 2010 political contributions went to Democrats, and none to Republicans? It's not even statistically possible that it MIGHT be representative. (source : http://www.opensecrets.org/pacs/pacgot.php?cmte=C00003806... )
