Fun fact about the union bosses' "free rider" argument

You know who is the about only group opposed to exempting non-union workers from union-negotiated benefits?  Union bosses. 

You see, being "forced" to share benefits with non-union workers, even if they fought to keep it that way, gives them a talking point to whip up opposition to it.

If you're a union member who opposes non-union members getting union-negotiated benefits, your union leaders are your enemy.
