I also don't think nonunion workers should be forced to pay union dues, but let me play devil's advocate for a second.
Conservatives usually say that minimum wage laws should be repealed because the government has no right to tell businesses what to pay their employees. If the worker doesn't like what he's getting paid, they argue, he should just get another job. So don't you think that if a worker doesn't want to pay union dues, he should just look for another job?
There is a hellofa difference between "forced unionism" and the minimum wage laws. [BTW, I am opposed to minimum wage laws as well.] Forcing someone who otherwise might like their job to pay union dues under threat of losing their job is tryanny of the worse sort.
People have a right to voluntarily join together in labor unions, but they certainly do not have the right to force anyone else to support them.
The crime is called extortion. It is a protection racket which benefits only the union bosses and should never have been allowed into law. America is a poorer nation and all Americanx have all suffered grievous harm because of this flawed notion.
