What do unions do for worker?

They will tell you that they are going to get you better pay and benefits and, in some cases they will...at first. Sooner or later though your company will not be able to keep up with union demands and your job will be sent outside the US where unions can't go and survive. That is the reason that General Motors who used to be the largest employer in the U.S. is now the largest employer in Mexico. So now the unions are trying to get a one world order so they can go anywhere there are jobs.

Workers used to need protection from bully employers. Now they also need protection from bully unions.
