@doctormo Agree with the impulse to separate from company HR, and, in fact, many unions do operate (well or poorly) as semi-independent HR bodies, but that's still what we used to call class-collaborationist, or later, business unionism. W.Z.Foster, in the TUEL days, spoke about this. More recently, Laurent Cantet's film Ressources Humaines explores this with subtlety and ferocity.
