Traditional professional values professed by physicians make us think twice about collective bargaining. Somehow it seems unprofessional. There's no reason for collective bargaining if you enjoy losing. One does not sacrifice an iota of professionalism by joining a union.
Unions make sure that people get treated fairly.
The real revolution is that gigantic corporations treat professional employees like chattel and that the nature of professional deportment precludes fighting back in a forceful and organized fashion. The emerging counterrevolution is that professional people are forming their own unions. The UAPD is part of this counterrevolution. Not so long ago physicians were worried about the threat from the left in the form of government controlled medicine. The big worry then was socialized medicine.
