Unions Have Monopoly Power, Not "Bargaining Rights"

See Collective Bargaining "Rights" by David Henderson at EconLog. Here is an excerpt:

"Almost everyone on both sides of the debate uses the term "collective bargaining rights" to mean the right of a union to bargain with an employer who must, by law, bargain in good faith. It also includes the right of a union to negotiate even for employees who don't want to be members of the union and don't want to pay dues to the union. So "collective bargaining rights" really mean the power to force others--to pay the dues and/or to join the union and/or to give up their power to negotiate with an employer. So the alleged right is really the "right" to monopolize the supply of labor to an employer. That's a phony right, not a real right. It's really a power."

He goes on to say that even economists who support unions agree with this.
