What I love are unions that set abnormally high union initiation fees, only offer payment plans on people who sign dues check off forms, then include language in that dues check off form that keeps you from cancelling it unless you do so during a 15 day window every year.
As long as unions can forced on empolyees, unions can not be a market-based economy, it can not ever act against the interest of the empolyees it serves.
Why is it harder for a workplace to leave a union that is no longer serving its interests (to none or another union) then it is for the union to form in the first place?
