The right to freely interact with other consenting adults, which is variously described as the right to free association, and the right to contract, is a foundational principle of a free society, and we see various reflections of that in the legal rights found in many charters and bills of rights and constitutions.

>>An employer is a collection of people, so is a union.

I am not opposed to people forming a union. I'm opposed to regulatory restrictions preventing employers from refusing to negotiate with unions or employ their members.

Do you only oppose this type of employment discrimination or do you oppose employment discrimination in general?

What do you mean by employment discrimination?

There is probably a better source, but general examples of what I mean can be found here. [0] More details regarding discrimination based on union sympathies can be found here. [1]

I support the right of private employers to discriminate against employees for anything, including despicable premises like sex and race. If you are the government, you should only be allowed to discriminate based on actions that could adversely affect government efficiency, and being party to a union falls under that.
