I'd love to see better information on alternative collective bargaining to unions, which is a loaded word in the U.S. I've never worked as a union member, but my impression from working with them is that they undermine their own success long term by over protecting incumbent members and reducing organizational agility, but do a good job of improving the live of their averages member in the short to midterm. I've often mused on how to make collective bargaining work better without much success. I wonder if employee owned corporations that function like contractors would be better (the employees start working for the union once the collective bargaining goes into effect.)
