i think one needs to consider the hx of unions from the turn of the century to present day
unions are what made a prosperous middle class in America, mostly after WW2
the people that initiated them had nads, even in light of oppositional entities like the pinkertons
the unions have even smartened up to current times, being we are now in the days of outsourcing jobs faster than creating them.
seems they are a big (if not biggest) advocate of NHC, realizing that it is any empolyers biggest liability
as such, to be in the health care community, and be union, would be to advocate NHC
