Here's a link to OK right to work for less law: http://www.nrtw.org/c/okrtwlaw.htm
Quote: "B. No person shall be required, as a condition of employment or continuation of employment, to:
...3. Pay any dues, fees, assessments, or other charges of any kind or amount to a labor organization..."
Now, unless you have some update on OK's law -a link, which allows a "service fee" that a union can charge when a non-union member benefits, I suggest you concede the point.
The issue should be resolved at the SCOTUS level; allowing even one state to corrupt contract law should never be allowed. RTW states should have simplified matters by going with a bare-bones "Open Shop" law, instead.
"Think logically". That's a good sig; you should try it this time.
