Thanks for the info BB. My mom was a phlebotomist in the SEIU for a long time (until changing workplaces, she's no longer in a union) and the way she described it was about the same as you (union did nothing, invisibility except on her paycheck, etc.). She hated (and still hates) the union with a passion.
I'm not convinced about the issue of industrial versus craft unions in this specific instance. Obviously if there were radical rank n file activity it would have to be industrially based rather than craft based (because it's impossible to organize on a class basis in craft unions), but it's not like the SEIU is organizing workers into class based, class conscious organizations either. They are all about partnership with management. Industrial unionism opens possibilities that are not open to craft unions but it doesn't mean that there is an automatic radicalism adhering to industrial unions. This might have appeared to have been the case a 100 years ago but I don't see how we can still believe this today.
(That said, I have no real opinion on this conflict between the unions since I haven't worked in that workplace and don't know the contracts.)

Yeah. I took a look at some of the UHW AMR contracts a couple of years ago. Pretty crap. I had an AMR shop in another state as well. Also crap. There was some sort of plan to do a national emergency services union but they mostly sucked too. Problem with ambulance companies is that they're more industrially related to firefighters than they are to the healthcare business but the IAF are against organizing them. It would make a lot more sense than SEIU. The way the contracts for services are handed down just aren't done the same way that other healthcare jobs are.
The CNA isn't a break away union. It was part of a national association of nurse craft unions that have been around for a long time. Currently there's something of a war within that association and the CNA is breaking away from the other nurse only unions. They raided another nurse only union in Illinois a couple of years ago as I recall.
