GfS, there are different unions. The teacher's union is one of the last hopes we have for a decent educational system in the US. There is not corruption but integrity there.

They're not all Jimmy Hoffa or gangster-controlled. Many have the genuine interest of working people such as the UMWA. The anti-union propaganda that has permeated the
likes of mainstream media is based on those who stand to benefit from the destruction of
unions, those who control broadcast and print media in the US.

Unions have always served important functions for working people and the proof is the rise of the middle class during the Administration of FDR. Reagan gutted that and the US is paying the cost by rising unemployment and CEO wages proportionately. Here is corruption at its worst.
