There is a disconnect here.
In the free market, I ought to be able to join a company with a union contract and be able to negotiate my own wages/benefits etc. When the government is preventing me from doing so, that is an overstepping of the bounds of government. "workers rights" laws that interfere with a company's ability to handle employment as they see fit are also ridiculous for that reason. The government does not need to hold our hands and help us keep our jobs. We should be able to keep our jobs fairly in competition with others in the market, or we won't have them. That is how you have productive, healthy businesses.
My real issue with the current job enviornment is the ability of an employer to terminate a person without any just cause. If a person is a deadbeat, poor attendence, unsafe, or whatever then that is justified and I have no issue with that. However, when a employer can just walk out to a shop floor and tell everyone they are taking a 20% cut just because they want to do it then that is what breeds unions. Also, it is not right for an employer to be able to fire a person because they have a safety issue with a job. It has happened and does happen still to this day and before you cry OSHA you might want to think about what the small odds are they will ever see you or the unsafe work conditions
The first argument from most people will be that you should just quit and find another job if you don't like the situation your current one is putting you in. On that same note you can quit your current union job if you don't like paying union dues or better yet go to a direct non-union competitor with your skills and out perform the union factory. It should work just fine according to most here with their free market fantasy but it doesn't work that way in real life and it is not the unions fault.
If you think back 20-30 years ago you did not see schools being shut down and teachers getting layed off because there was a huge tax base paying into the system. This tax base was from good paying industry jobs rather then the low paying garbage industry jobs we have making up a large portion of the formerly middle class. When this country went with NAFTA and even more manufacturing in China before and after NAFTA is when it all really went downhill.
