With whom I work basically depends on who is supporting what cause. For instance, I've worked with AFL-CIO officials like Don Slaimon, who boasts of having worked to create "free & independent unions" in then socialist societies, especially during the strike of OSU workers in CWA Local 4501 in 2000 -- the kind of guys who are diametrically opposed to the Workers World Party on the question of the Chinese state, workers, & intellectuals. I endorse neither's position on China, but that shouldn't prevent me from working with both -- with union officials when a local strike has to be supported, with Workers World organizers when an anti-war rally needs to be held at the moment when the precious few are willing to do anything.

P.S. On things Chinese I've found my on-line pal Steve Philion's take to be agreeable.
