Arguably, a union has to hold the position of requiring membership, and against those who don’t want to join. Collective bargaining only works when your position represents the group to the point where it can’t be dismissed.
But yeah, It’s challenging for a union to remain exclusively dedicated to serving its membership. I think it’s increasingly complicated with national unions which exist for the sake of unions as a concept, but not necessarily any union members.
Unions doesn't work that way in Europe, it is not something unions must do.
Collective bargaining works as long as you are a collective that bargains together, you don't need to have every single person be a art of that collective.

It’s weird.
