Ahem, look around. Unionism IS dead. Where unions still exist, they are marginalized to the extent that they are nothing but contract bargaining representatives, with 'bargaining' de-emphasized.
So called 'Right to Work' laws have killed unions and crippled wages and benefits for middle class jobs, turning them into lower-middle class or part-time positions.
Our 'union' right to self help (strike) has been taken away by PEB's.
Companies dictate to the unions and use bankruptcy laws to slash and burn legal contracts.
Our country is poorer for this turn of events. The pension is a thing of the past, paid health care is all but eradicated, and vacation time goes unused nationwide. Wages are stagnant or worse, and the next generation of workers is eager to take your job and do it for less.
Do we belong to a union, or a professional association? Do most of our ex-military/conservative pilots vote republican or democrat?
In order to have unionism, the membership must be onboard and supportive. I have not seen that characteristic demonstrated in any union I've been associated with, whether it was ALPA, USAPA, or APA.
