One thing that has killed the UAW is their 100% alliance with the Baraqqi Coalition. Effective adverts showing the UAW supporting abortion and gun control helped their defeat at VW.
Back in the “old” days some unions like the Teamsters, etc actually supported things like the 2nd amendment, strong defense, etc.
Unions exist for the purpose of collective bargaining with the owners of the company. ANY OTHER activity is STEALING from the union members. Labor law, as regards unions and the relationships among unions, their members, and their members' employers is hopelessly corrupt ... it should all be repealed and replaced.
