Anne Martens—tweeting as @glossolaliac, who I recommend following—directs our attention to this article in Slate:

Crain's New York Business, New York Magazine, and The Village Voice are reporting that a "a loose coalition of labor and community groups" have pledged solidarity with the protests at Zuccotti Park in New York's financial district and are organizing a march for next Wednesday, October 5.

The list of labor groups involved in Wednesday's planned march include: The United Federation of Teachers; 32BJ SEIU & 1199 SEIU; Workers United; and Transport Workers Union Local 100, which has 38,000 members.

Additionally, Working Families Party,, Make the Road New York, the Coalition for the Homeless, the Alliance for Quality Education, Community Voices Heard, United New York and Strong Economy For All are involved in the organization of the march.

Good for them.
