The USPP is the United States Pirate Party. I generally disapprove of political parties, but the Pirate Party supports social freedoms and anonymity without being overtly An-Cap. I joined it because I believe in these things, am a pirate, and because the party could use all the members it can get.
I know, of course, that syndicalists don't want trade unions, I was a syndicalist for a long time, and an IWW member. But the reality is, that the union, as it actually functions (regardless of its stated goal) is to represent workers in negotiation with the bosses, so they will always head down the path of recuperation.
In periods of high class consciousness we are going to see the self-organization of the working class into bodies that best represent their ideas and most effectively see to their needs. I don't pretend to know the future and what these will be, but for the most part I think the past dictates that they will be some sort of soviet/workers & residents council/strike & workplace comittee.
The union exists as tool to bargain with the bosses, even radical unions, this is what they do day-to-day. So the radical rhetoric is just that, unions have never made revolution, nor are they necessary to "teach" workers how to organize.
