Think about this for a minute:
Unions started for a great reason, to ensure that workers were not taken advantage of in the workplace. Safety was one of the main reasons and quality was another. Now, things have changed. Tell a union worker he/she has to wear safety glasses in an area or a plant where they have not been previously required and it takes an act of God. Or, tell a union worker that he/she must get a certification to keep the job...forget it, they all want grandfathered, not me they say, I can do the job wihtout the schooling, wihtout the new training, without proving that I know what I am doing, and the union will fight for them. Nuts. Absolutely. Freaking. Nuts.
Oh, and try to change something for the betterment of the workers...forget about it, no constructive help from the union, just crappy attacks and useless ad hominem.
Screw 'em all.
