I've been at or supervised a fair number of union meetings, and if you don't think they're pretty rambunctious, if you don't think unionized employees are heavily involved in criticizing, challenging their union, that's not my experience.
They're not wee, timorous beasties. Union elections are contested. Expenditures are contested. There are passive union members who don't participate, but there are very active ones. I don't think the appellation “unaccountability” is true.
The difference is this. There's a lot of accountability to the members of the bargaining unit. The real issue, as one of the construction reps earlier said, is the access to the information to the outside world to use for political purposes, to use for economic purposes, for sniping—all that goes on. This is just part of the battle.
